Getting started

Installing u-center 2 software
u-center 2, the u-blox interactive evaluation software tool is required for configuration, testing, visualization and data analysis of u-blox GNSS receivers as well as EVKs. The EVK user guide together with the u-center 2 evaluation tool provide useful assistance during all phases of a system integration project. To install the u-center 2 evaluation software tool, follow the steps available on www.u-blox.com/product/u-center. For more information on how to use the u-center 2 evaluation software tool, refer to the u-center 2 User guide [4].
The required Windows drivers for the FTDI FT2232D USB-to-UART converter that is used in the EVK are available from the Microsoft Windows Update service. To ensure that the latest FTDI drivers are installed automatically from Windows Update, check and uninstall the previously installed FTDI drivers. The Windows system driver search mechanism will download and install the FTDI drivers automatically from the Microsoft Windows Update service. If the automatic installation fails, contact u-blox support to get the FTDI drivers and install manually.

Device description

EVK-M10QSAM evaluation kit contains SAM-M10Q concurrent GNSS module embedded with a GNSS patch antenna, along with a built-in USB interface which provides both power supply and high-speed data transfer, and eliminates the need for an external power supply as shown in Figure 5.

Interface connection
The EVK-M10QSAM supports UART and I2C communication interfaces. To connect the EVK to a PC, use a standard SUBD-9 cable or the included USB cable depending on the interface in use. The EVK also includes an on-board USB-to- Serial converter for USB-to-UART communication with the receiver. For current measurements and to evaluate the available digital interfaces, additional measurement equipment and devices can be connected to the 14-pin connector on the front side of the EVK unit. The EVK design allows the front side pins to be used simultaneously with the other ports.
Do not drive any of the IO pins when the EVK is not connected to a power supply.

Figure 1: Connecting the EVK-M10QSAM unit for power supply and communication
Figure 2 shows the front and back side of the EVK-M10QSAM evaluation unit.

Figure 2: EVK-M10QSAM front and back side

Interface switch
Use the interface switch on the front side of the evaluation kit to choose between the RS-232 and USB communication ports.

CAUTION Changing the interface switch position while the EVK is powered on may damage the GNSS receiver chip. Power off the EVK before changing the interface switch setting.

• RS-232 – In this selection, the EVK operates with the RS-232 (DB9 – back side).
• USB – In this selection, the EVK operates only with the USB interface. RS-232 (DB9) is switched off.

14-pin connector
The EVK-M10QSAM front side has a 14-pin connector that provides programmable input/output signals, communication interfaces and supply options. All these pins are ESD protected. The 14-pin connector can be used for communicating with the receiver through the UART and I2C interfaces. In addition, the 14-pin connector provides flexibility for evaluating other advanced scenarios.

Figure 3: EVK-M10QSAM 5.0 V DC power supply example

• When using the 3.3 V digital interfaces with your application (e.g. I2C), a cable length less than 25 cm is recommended.

USB
The USB connector in the evaluation kit can be used for both power supply and communication. The easiest way to evaluate the EVK-M10QSAM operation is to connect the EVK to a PC with the USB cable and then to use the u-center 2 tool to configure and monitor the GNSS functions. The USB connector is internally connected to a USB-to-Serial converter that connects to the UART interface of the u-blox M10 receiver on the EVK. This allows the USB connector to be used for communication as well. Interface switch can be used for USB communication with the receiver.
When the EVK is connected to the PC, Windows creates a virtual COM port to the PC. This newly created virtual COM port needs to be selected in the u-center 2 evaluation tool for communicating with the receiver. EVK-M10QSAM supports USB- to-UART communication speeds up to 921600 baud.

UART
The EVK unit includes two options for the UART connection, via the RS-232 serial port or the 14-pin connector. By default, the UART communication speed is set to 9600 baud and EVK-M10QSAM supports speeds up to 921600 baud.

RS-232
The EVK can be connected to a PC using a maximum 3 m straight RS-232 serial cable with male and female connectors. The RS-232 port needs to be configured to connect to the PC. To do this, use the UBX-CFG-VALSET command and select the CFG-UART1 Configuration group in the u-center 2 evaluation tool. The maximum operating baud rate is 230400 baud. Note, if a USB-to-RS-232 adapter cable is used, it can be connected directly to the RS-232 port of the evaluation kit. The RS-232 port also provides a TIMEPULSE output signal.
The 9-pin RS-232 female connector is assigned as listed below:

Pin no.:  Assignment

• 1 & 6 Time pulse
• 2 TXD (GNSS Transmit Data)
• 3 RXD (GNSS Receive Data)
• 4 not connected
• 5 GND
• 7, 8 & 9 not connected

Table 5: EVK-M10QSAM RS-232 connector pin description

UART through 14-pin connector
The EVK also provides UART communication through the 14-pin connector on pins TxD and RxD. See section 14-pin connector for more information.

I2C
The 14-pin connector contains pins for evaluating I2C bus communication. By default, the I2C pull-up resistors are populated on the EVK board which help if fast communication speed with long cable length is needed.

GNSS input signal
The SAM-M10Q module is embedded with a GNSS patch antenna and the signal is further filtered and amplified by the internal SAW filter and internal Low Noise Amplifier (LNA). For more information, see the SAM-M10Q Hardware Integration Manual [2].
External antenna connectivity through SMA connector is not available in the EVK-M10QSAM.

Time pulse
u-blox receivers include a time pulse function that provides pulses with a configurable pulse period, pulse length and polarity (rising or falling edge). The u-center 2 evaluation tool can be used to configure the time pulse parameters. The time pulse signal is available at the 14-pin and RS-232 connectors. In addition, the time pulse signal is inverted and connected to the LED on the front side of the EVK.
The time pulse signal from the 14-pin connector has 50 ohms output and thus, no fast slope output signal is possible.

Reset button
The RST button on the front side resets the SAM-M10Q module.

4.5 Safe boot button
This button is used to set the receiver into safeboot mode. In this mode, the receiver executes only the minimal functionality.
The safeboot mode is not recommended in EVK-M10QSAM because the u-blox M10 receiver is using a ROM-based firmware and thus, it is not necessary to go into safe boot mode.

LED
On the front side of the EVK unit, a single blue LED shows the time pulse signal as well as the status that the device is powered on. The LED starts flashing one pulse per second during a GNSS fix. If there is no GNSS fix, the LED will only be lit, without flashing.

Backup Battery
There is a backup battery in the evaluation unit. This is necessary to store orbital information
between operations and to enable faster start-up. It is a RENATA 3.0 V Li / MnO² battery of the type CR2450. The battery has a rated capacity of 540 mA. The battery operating temperature range is -40° C to +85° C. In case the built-in backup battery runs low or empty after a long storage period, purchase the above described battery for replacement.

• CAUTION Risk of explosion if battery is replaced by an incorrect type. Make sure that battery is of the correct specification.
• CAUTION Risk of short circuit when touching the battery with conducting parts. Do not use conductive parts to remove or touch the battery.

External interrupt
On the EVK-M10QSAM, the external interrupt (EXTINT) signal is available on the 14-pin connector. The EXTINT signal can be used for time mark and time aiding features of the receiver, as well as for waking up the receiver from power save modes. See section 14-pin connector for more information.

Measuring current

Measuring GNSS current
At startup, the receiver starts in acquisition mode to search for available satellites and to download GNSS orbital data, i.e., ephemeris and almanac. Once the data has been downloaded, the receiver enters tracking mode. In continuous operation, the receiver typically remains in tracking mode once entering it. The current consumption reduces when the receiver enters the tracking mode. The time required to enter tracking mode can be reduced by downloading aiding data from the AssistNow™ Online service.
On EVK-M10QSAM, the main supply voltage for the u-blox M10 GNSS receiver is 3.3 V. To measure the total GNSS supply current with EVK-M10QSAM, follow these steps:

1. Power up EVK-M10QSAM.
2. Connect a true RMS voltmeter across P1A (pin 12) and P1B (pin 11) of the 14-pin connector.
3. Read the voltage (and average if necessary) on the voltmeter and convert to current (1 mV equals 1 mA).
4. Perform the test with good signals and clear sky view to ensure that the receiver can acquire the satellite signals.

For more details see the setup below.

Figure 4: Example – tracking current measurement

Measuring backup current
To measure the backup current (IBCKP) with EVK-M10QSAM, follow these steps:

1. Connect a true RMS voltmeter across P2A (pin 10) and P2B (pin 9) of the 14-pin connector.
2. Remove power supply (USB cable or other external power supply from the 14-pin connector).
3. Read the voltage (and average if necessary) on the voltmeter and convert to current (1 mV equals 10 µA).

Device configuration

This section shows how to configure and evaluate some important receiver features on EVK-M10QSAM related to power modes, GNSS constellations, navigation rate of the receiver. In addition, the receiver can be configured with the Advanced Configuration View of the u-center 2 evaluation tool as shown in Figure 9.

Figure 9: EVK-M10QSAM receiver configuration view
The receiver configuration can be saved to the receiver RAM, or to the battery- backed RAM (BBR). The RAM content is cleared after the power supply is disconnected or in software standby mode and the off state of On/Off power save mode (PSMOO). Therefore, it is recommended to save the receiver configuration to RAM and BBR. The BBR content is maintained as long as the backup battery supply is available.

Communication ports
The FTDI USB-to-UART converter generates two virtual communication (COM) ports as shown in Figure 10. The first COM port based on the COM port ID is the correct port to use. For example, if the generated COM ports are COM1 and COM2, then the port to use is COM1.
If the RS-232 port is also connected to the same PC, there will be an additional COM port for the RS-232 serial connection.

Figure 10: EVK-M10QSAM communication ports
The COM ports may appear differently in different Windows versions. For example, in Windows 10 it appears as shown in Figure 11.

Figure 11: EVK-M10QSAM communication ports identification on Windows

UART baud rate configuration
The baud rate for the UART communication to the receiver can be configured in the CFG-UART1-BAUDRATE configuration key. The default baud rate is set to 9600 as shown in Figure 12, and the maximum baud rate is 921600.

Figure 12: EVK-M10QSAM UART baud rate configuration

Setting a different baud rate will interrupt communication. If other configuration keys were set after, these will not be applied. Therefore, the new baud rate needs to be selected manually to resume communication and apply the remaining configuration items.

GNSS configuration
The default GNSS constellations that are enabled on the receiver are GPS, Galileo, GLONASS, BeiDou B1C, SBAS and QZSS. The receiver GNSS configuration can be updated by selecting the constellations in the GNSS Configuration View as shown in Figure 13.

Figure 13: EVK-M10QSAM receiver GNSS configuration

Navigation update rate
The CFG-RATE-MEAS configuration key that is shown in Figure 14 can be used to configure the navigation update rate. The navigation update rate value is defined in ms, where 100 ms corresponds to 10 Hz. The default update rate is 1000 ms which corresponds to 1 Hz. The default 1 Hz update rate is a good tradeoff between position accuracy and power consumption. Certain applications require faster update rates for high performance but this will increase the receiver power consumption.
Increase the communication baud rate and reduce the number of messages that are enabled when high navigation update rates are used. The maximum baud rate of 921600 or 460800 baud rate should be sufficient for most use cases.

Figure 14: EVK-M10QSAM receiver navigation update rate configuration

Power modes
EVK-M10QSAM supports the following power modes and can be configured with the CFG-PM-OPERATEMODE configuration key.

• Continuous mode (FULL): This is the full power mode and the default mode of the receiver. No power save mode is active in this mode.

• On/Off mode (PSMOO): This is a power save mode for reducing the power consumption of
  the receiver. In this mode, the receiver is configured to be periodically turned on or off for applications that require less frequent position updates. Typically used for update periods longer than 10 seconds.

• Cyclic tracking mode (PSMCT): This is also a power save mode for applications that require more frequent position updates. Typically used for short update periods in the range of 0.5 to 10 seconds. In this mode, the receiver does not shut down completely between position fixes, but uses low-power tracking instead.
  BeiDou B1C is not supported in power save mode (PSM). Some PSM states clear the RAM memory. Store receiver configuration in BBR to maintain the settings. In addition, it is recommended to disable SBAS because the receiver is unable to download or process any SBAS data in PSM.

Figure 15 shows the configuration window for selecting the receiver power mode and configuring the position update period. For the On/Off power mode, the position update period is defined with the CFG-PM-POSUPDATEPERIOD. To maintain the configuration during an inactive state, save it both in the RAM and BBR layer.
The CFG-PM-OPERATEMODE configuration is applied last after other required power mode configuration items are defined in the CFG-PM group.

Figure 15: EVK-M10QSAM receiver power mode configuration

Backup modes
SAM-M10Q supports two backup modes: hardware backup mode and software standby mode.

• Hardware backup mode: In this mode, other supplies except the backup supply (V_BCKP) are turned off. On the EVK-M10QSAM, this is achieved by turning off the main power supply of the EVK either by removing the USB cable or the 5.0 V supply from the 14-pin connector.
• Software standby mode: In this mode, the receiver executes little or no system activity. To wake the receiver up from the software standby mode, the wakeup source can be configured in UBX-RXM-PMREQ message. The available wakeup sources are EXTINT and UART RxD signals. The duration in the UBX-RXM-PMREQ message can be set to 0 for putting the receiver to software standby mode indefinitely until a signal is detected from the configured wakeup source. In addition, ensure that the force option is selected.
  The RAM memory is cleared in the software standby mode and in the off state of PSMOO. To maintain the configuration during the inactive state, save it both in the RAM and BBR layer.

Refer to u-blox M10 interface description for more information on advanced configuration of the receiver [5].

Troubleshooting

My application (e.g. u-center 2) does not receive all messages
When using UART, check that the baud rate is high enough or reduce the number of enabled messages. The maximum baud rate of 921600 or 460800 baud rate should be sufficient for most use cases. If the baud rate is insufficient, GNSS receivers based on u-blox M10 GNSS technology will skip excessive messages. Some serial port cards/adapters (e.g. USB to RS-232 converter) frequently generate errors. If a communication error occurs while u-center 2 receives a message, the message will be discarded.

My application (e.g. u-center 2) loses the connection to the GNSS receiver
u-blox M10 positioning technology and u-center 2 have an autobauding feature. If frequent communication errors occur (e.g. due to problems with the serial port), the connection may be lost. This happens because u-center 2 and the GNSS receiver both autonomously try to adjust the baud rate, if the GNSS receiver has the autobauding enabled. Select a suitable baud rate from the available list in u-center 2.

Some COM ports are not shown in the port list of my application (e.g. u-center 2)
Only the COM ports that are available on your computer will show up in the COM port drop down list. If a COM port is gray or u-center 2 is not able to connect to the selected COM port, check if there is another application running on the computer that is using the same port.

There is no data received from the EVK after connecting the EVK to my application.
Check the interface switch position and ensure that it is set to the communication interface that is in use.
Do not change the interface switch while the EVK is still powered. Turn off the EVK, change the switch position and turn on the receiver.

EVK-M10QSAM is not able to use the available FTDI drivers automatically in Linux environment.
EVK-M10QSAM does not officially support Linux and the following configuration is only provided to map the available FTDI drivers to the connected EVK, which should be useful in most cases.
Map the FTDI drivers that are available in the Linux system to the EVK device by saving the following configuration in a new rules file under the /etc/udev/rules.d/ folder.
For example: > nano /etc/udev/rules.d/10-evk.rules
ACTION==”add” \, ATTRS{idVendor}==”1546″ \, ATTRS{idProduct}==”0506″ \, SYMLINK+=”ttyEVK%n” \,
RUN+=”/sbin/modprobe ftdi_sio” \ RUN+=”/bin/sh -c ‘echo 1546 0506 > /sys/bus /usb-serial/drivers/ftdi_sio/new_id'”
RUN+=”/bin/stty -F /dev/ttyEVK%n -clocal raw ispeed 9600 ospeed 9600″
The configuration will generate two ports as shown in the example in Figure 16 and the first port can be used for UART communication with the receiver.

Figure 16: EVK-M10QSAM communication ports in Linux environment

EVK-M10QSAM does not work properly when connected to a GNSS simulator
When using EVK-M10QSAM together with a GNSS simulator, please pay attention to proper handling of the EVK. A GNSS receiver is designed for real-life use (i.e. time is always moving forward). When using a GNSS simulator scenarios, the scenario time can be in the past resulting in the receiver to jump backwards in time. This can have serious side effects on the performance of GNSS receivers.
The solution is to configure the GPS week rollover value to a week number preceding the date in GNSS simulator scenario. For example, setting the GPS week number to 1200 (corresponding to Jan 2003) allows running simulator scenarios taking place after this date. Please refer to Figure 17 for how to set the GPS week number with u-center 2 GNSS evaluation tool. In addition, always issue a cold start command before every simulator test to avoid receiver confusion due to the time jumps.

Figure 17: Setting GPS week number with u-center 2 GNSS evaluation tool

Common evaluation pitfalls

• Parameters may have the same name but a different definition. GNSS receivers may have a similar size, price and power consumption but can still have different functionalities (e.g. no support for passive antennas, different temperature range). Also, the definitions of Hot, Warm, and Cold Start times may differ between suppliers.

• Verify design-critical parameters. Try to use identical or at least similar settings when comparing the GNSS performance of different receivers. Data, which has not been recorded at the same time and the same place, should not be compared. The satellite constellation, the number of visible satellites and the sky view might have been different.

• Do not compare momentary measurements. GNSS is a non-deterministic system. The satellite constellation changes constantly. Atmospheric effects (i.e. dawn and dusk) have an impact
  on signal travel time. The position of the GNSS receiver is typically not the same between two tests. Comparative tests should therefore be conducted in parallel by using one antenna and a signal splitter; statistical tests shall be run for 24 hours.

• Monitor the carrier-to-noise-ratio (C/N0). The average C/N0 of the high elevation satellites should be between 40 dBHz and about 50 dBHz. A low C/N0 will result in a prolonged TTFF and more position drift.

• Try to feed the same signal to all receivers in parallel (i.e. through a splitter) with identical cable length; the receivers will otherwise not have the same sky view. Even small differences can have an impact on the speed, accuracy, and power consumption. One additional satellite can lead to a lower dilution of precision (DOP), less position drift, and lower power consumption.

• When doing reacquisition tests, cover the antenna in order to block the sky view.
