Function description
Fixed transmission
Broadcasting transmission
Broadcasting address
- For example: Set the address of module A as 0xFFFF or 0x0000, and the channel as 0x04;
- When module is the transmitter (transparent transmission), all modules under channel 0x04 will receive the data, the purpose of broadcast is realized.
Monitor address
- For example: Set the address of module A as 0xFFFF or 0x0000, and the channel as 0x04;
- When module A is the receiver, it can receive the data sent from all modules under channel 0x04, the purpose of monitor is realized.
Reset
- When the module is powered, AUX outputs low level immediately, conducts hardware self-check and sets the operating mode based on user’s parameters. During the process, the AUX remains low level. After the process completed, the AUX outputs high level and starts to work as per the operating mode combined by M1 and M0. Therefore, users need to wait the AUX rising edge as the start of module’s normal work.
AUX description
- AUX Pin can be used as indication for wireless send & receive buffer and self-check.
- It can indicate whether there are data that are not sent yet via wireless way, or whether all wireless data has been sent through UART, or whether the module is still in the process of self-check initialization.
Indication of UART output
- To wake up external MCU
Indication of wireless transmitting
- Buffer (empty): the internal 1024 bytes data in the buffer are written to the RFIC (Auto sub-packaging).
- When AUX=1, the user can input data less than 1024 bytes continuously without overflow. Buffer (not empty): when AUX=0, the internal 1024 bytes data in the buffer have not been written to the RFIC completely. If the user starts to transmit data at this circumstance, it may cause overtime when the module is waiting for the user data, or transmitting wireless sub package.
- When AUX = 1, it does not mean that all the UART data of the module have been transmitted already, perhaps the last packet of data is still in transmission.
Configuration procedure of module
- Only happened when power-on resetting or exiting sleep mode
Operating Mode
The table below shows the status of corresponding modes:
Mode (0-7)| M2| M1| M0| Mode introduction|
Remark
---|---|---|---|---|---
0 RSSI mode| 0| 0| 0| UART opens. Wireless closes and transmission is
unavailable.| Module outputs RSSI value each 100ms through UART
1 Continuous mode| 0| 0| 1| UART opens. Wireless closes and continuous
transparent transmission is available.| Air data rate can be adjusted
automatically according to baud rate. The baud rate must be same on both
receiver and transmitter. It is applicable for high speed continuous data
transmission.
2 Sub-package mode| 0| 1| 0| UART opens. Wireless closes and sub-package
transparent transmission is available.| Air data rate and baud rate can be
adjusted separately. It is applicable for data packet transmission.
3 Configuration mode| 0| 1| 1| UART opens. Wireless closes and parameter can
be configured.| Baud rate is fixed as 9600 8N1.
4 WOR mode| 1| 0| 0| UART opens. Wireless closes and sub-package transparent
transmission is available.| Receiving is not available under this mode.
Preamble code will be added proactively before transmission to wake up the
receiver under mode 6.
5 Configuration mode (Same as Mode 3)| 1| 0| 1| –| –
6 Power saving mode| 1| 1| 0| UART closes. Wireless works at WOR power saving
mode. Multiple time grades can be configured.| Transmission is not available
under this mode. It can be woken up by transmitter under mode 4 to achieve
low power consumption receiving.
7 Sleep mode| 1| 1| 1| UART closes, wireless transmitting is available and
sleep mode is on.| It can be woken up by any falling edge of M2, M1, M0.
Mode Switch
- The user can decide the operating mode by the combination of M0, M1 and M2. The two GPIOs of MCU can be used to switch mode. After modifying M0, M1 or M2, it will start to work in new mode 1ms later if the module is free. If there are any serial data that are yet to finish wireless transmitting, it will start to work in new mode after the UART transmitting finished. After the module receives the wireless data & transmits the data through serial port, it will start to work in new mode after the transmitting finished. Therefore, the mode-switch is only valid when AUX outputs 1, otherwise it will delay.
- For example, in mode 2 or mode 4, if the user inputs massive data consecutively and switches operating mode at the same time, the mode-switch operation is invalid. New mode checking can only be started after all the user’s data process completed. It is recommended to check AUX pin out status and wait 2ms after AUX outputs high level before switching the mode.
- If the module switches from other modes to stand-by mode, it will work in stand-by mode only after all the remained data process completed. The feature can be used to save power consumption. For example, when the transmitter works in mode 0, after the external MCU transmits data “12345”, it can switch to sleep mode immediately without waiting the rising edge of the AUX pin, also the user’s main MCU will go dormancy immediately. Then the module will transmit all the data through wireless transmission & go dormancy 1ms later automatically, which reduces MCU working time & save power.
- Likewise, this feature can be used in any mode-switch. The module will start to work in new mode within 1ms after completing present mode task, which enables the user to omit the procedure of AUX inquiry and switch mode swiftly. For example, when switching from transmitting mode to receiving mode, the user MCU can go dormancy before mode-switch, using external interrupt function to get AUX change so that the mode-switch can be realized.
- This operation is very flexible and efficient. It is totally designed on the basis of the user MCU’s convenience, at the same time the work load and power consumption of the whole system has been reduced and the efficiency of whole system is largely improved.
RSSI Mode (Mode 0)
Status | M0=1 M1=0 M2=0 |
---|---|
Transmitting | Wireless data transmission is not available |
Receiving | Wireless data receiving is not available |
Baud rate & air data rate | Current baud rate |
Advantage | RSSI value of one byte output every 100ms can indicate the noise |
value of current environment.
Disadvantage| Data transmission and receiving are not available
Applications| For monitoring environmental noise
Note| –
Continuous Mode (Mode 1)
Status | M0=1 M1=0 M2=0 |
---|---|
Transmitting | Wireless data transmission is available. |
Receiving | Wireless data receiving is available. |
Baud rate & air data rate | Module will calculate the minimum air data rate |
according to the configured baud rate. Since the modules with different air
data rate cannot communicate, the serial port parameters must be the same on
both receiver and transmitter.
Advantage| The data output on the receiver is continuous, it meets the
requirements for MODBUS continuous transmission and low latency.
Disadvantage| The baud rates on both receiver and transmitter must be same.
The module will raise its air data when the baud rate is raised, thus the
receiving sensitivity will be lowered and operation range will be shorter.
Applications| Applicable for those applications not requiring distance but
continuous data and response time.
Note|
- The “wireless air data rate” in the configuration commands is invalid (SPED.210 bits) and software will calculate automatically.
- 0000 and FFFF are the broadcast addresses, which can be used to monitor and broadcast.
- The addresses and baud rates must be same on both receiver and transmitter.
- In continuous mode, both transmitter and receiver must be same model. For example, E70 (868T14S) and E70 (868T30S) cannot communicate in continuous mode.
Sub-package Mode (Mode 2)
Status | M0=0 M1=1 M2=0 |
---|---|
Transmitting | Wireless data transmission is available. |
Receiving | Wireless data receiving is available. |
Baud rate & air data rate | Under this mode, the baud rate and air data rate |
are independent, both receiver and transmitter can have different baud rate
but same air data rate.
Advantage| Very low air data rate can be configured for longer distance, the
data continuousness between output data depends on the data packet length.
Disadvantage| Since the air data rate is low and the receiver needs to wait
for the data packet length or timeout byte numbers, it may cause some delay,
which depends on the actual value as set.
Applications| Applicable for those applications requiring distance and
continuous data while not requiring transmission speed.
Note|
- Air data rate and baud rate are not relative; the values are valid.
- 0000 and FFFF are the broadcast addresses, which can be used to monitor and broadcast.
- The addresses and air data rates must be same, but baud rates can be different on both receiver and transmitter.
- The size of individual data packet depends on the sub package size CHAN [7:5] (excluding address and channel for directional transmission)
Configuration Mode (Mode 3)
Status | M0=1 M1=1 M2=0 |
---|---|
Transmitting | Transmission not available, serial data received will be |
discarded.
Receiving| Receiving is not available.
Configuring| Parameter configuration can be made in configuration mode with
specific instruction format and UART 9600, 8N1.
Note| When entering other modes from configuration mode, the module will
reconfigure parameters, AUX keeps low
level during configuration;
After configuration completed, it outputs high level, so users are recommended
to check the AUX rising edge.
Wake-up Mode (Mode 4)
Status | M0=0 M1=0 M2=1 |
---|---|
Transmitting | Transmission is available. |
Receiving | Receiving is not available. |
Baud rate & air data rate | Under this mode, the baud rate and air data rate |
are independent, both receiver and transmitter can have different baud rate
but same air data rate.
Advantage| It can wake up the receiver under mode 6; wake up code will be
added automatically before transmitting, the code number depends on the wake
up time.
Disadvantage| The transmission time is long, only applicable to wake up the
receiver, not applicable for common data transmission.
Applications| For waking up the receiver under WOR mode.
Note| Under wake up mode, the single data packet length is 84 bytes (excluding
the address and channel for directional transmission).
Configuration Mode (Mode 5)
Status | M0=1 M1=0 M2=1 |
---|---|
Transmitting | Transmission is not available. Serial data received are |
considered as configuration command.
Receiving| Receiving is not available.
Configuration| Parameter configuration can be made in configuration mode with
specific instruction format and UART 9600, 8N1.
Note| When entering other modes from configuration mode, the module will
reconfigure parameters, AUX keeps low level during configuration;
After configuration completed, it outputs high level, so users are recommended
to check the AUX rising edge.
Power Saving Mode (Mode 6)
Status | M0=0 M1=1 M2=1 |
---|---|
Transmitting | Transmission is not available. |
Receiving | Receiving is available. |
Baud rate & air data rate | Under this mode, the baud rate and air data rate |
are independent, both receiver and transmitter can have different baud rate
but same air data rate.
Advantage| The module works under WOR status, it wakes up periodically and
monitors the wireless data packets, when data packet monitored, the module
enters receiving mode and receives complete data packets, and outputs the data
through serial port, and then enters WOR status again, which can save power
consumption significantly.
Disadvantage| Transmission is not available under this mode, the module must
be switched to other mode for data transmission.
Applications| Applicable for those devices which have requirement on power
consumption and need to receive data.
Note| It can only receive the data sent from the transmitter under mode 4.
Sleep Mode (Mode 7)
Status | M0=1 M1=1 M2=1 |
---|---|
Transmitting | Transmitting is not available. |
Receiving | Receiving is not available. |
Others | Other functions of the module are closed, only can quit sleep mode by |
switching the M0, M1 and M2 status.

Hardware design
- It is recommended to use a DC stabilized power supply. The power supply ripple factor is as small as possible, and the module needs to be reliably grounded.;
- Please pay attention to the correct connection of the positive and negative poles of the power supply. Reverse connection may cause permanent damage to the module;
- Please check the power supply to ensure it is within the recommended voltage otherwise when it exceeds the maximum value the module will be permanently damaged;
- Please check the stability of the power supply, the voltage can not be fluctuated frequently;
- When designing the power supply circuit for the module, it is often recommended to reserve more than 30% of the margin, so the whole machine is beneficial for long-term stable operation.;
- The module should be as far away as possible from the power supply, transformers, high-frequency wiring and other parts with large electromagnetic interference.;
- High-frequency digital routing, high-frequency analog routing, and power routing must be avoided under the module. If it is necessary to pass through the module, assume that the module is soldered to the Top Layer, and the copper is spread on the Top Layer of the module contact part(well grounded), it must be close to the digital part of the module and routed in the Bottom Layer;
- Assuming the module is soldered or placed over the Top Layer, it is wrong to randomly route over the Bottom Layer or other layers, which will affect the module’s spurs and receiving sensitivity to varying degrees;
- It is assumed that there are devices with large electromagnetic interference around the module that will greatly affect the performance. It is recommended to keep them away from the module according to the strength of the interference. If necessary, appropriate isolation and shielding can be done;
- Assume that there are traces with large electromagnetic interference (high-frequency digital, high-frequency analog, power traces) around the module that will greatly affect the performance of the module. It is recommended to stay away from the module according to the strength of the interference. If necessary, appropriate isolation and shielding can be done.
- If the communication line uses a 5V level, a 1k-5.1k resistor must be connected in series (not recommended, there is still a risk of damage);
- Try to stay away from some physical layers such as TTL protocol at 2.4GHz , for example: USB3.0;
- The mounting structure of antenna has a great influence on the performance of the module. It is necessary to ensure that the antenna is exposed, preferably vertically upward. When the module is mounted inside the case, use a good antenna extension cable to extend the antenna to the outside;
- The antenna must not be installed inside the metal case, which will cause the transmission distance to be greatly weakened.
FAQ
Communication range is too short
- The communication distance will be affected when obstacle exists.
- Data lose rate will be affected by temperature, humidity and co-channel interference.
- The ground will absorb and reflect wireless radio wave, so the performance will be poor when testing near ground.
- Sea water has great ability in absorbing wireless radio wave, so performance will be poor when testing near the sea.
- The signal will be affected when the antenna is near metal object or put in a metal case.
- Power register was set incorrectly, air data rate is set as too high (the higher the air data rate, the shorter the distance).
- The power supply low voltage under room temperature is lower than 2.5V, the lower the voltage, the lower the transmitting power.
- Due to antenna quality or poor matching between antenna and module.
Module is easy to damage
- Please check the power supply source, ensure it is 2.0V~3.6V, voltage higher than 3.6V will damage the module.
- Please check the stability of power source, the voltage cannot fluctuate too much.
- Please make sure antistatic measure are taken when installing and using, high frequency devices have electrostatic susceptibility.
- Please ensure the humidity is within limited range, some parts are sensitive to humidity.
- Please avoid using modules under too high or too low temperature.
BER(Bit Error Rate) is high
- There are co-channel signal interference nearby, please be away from interference sources or modify frequency and channel to avoid interference;
- Poor power supply may cause messy code. Make sure that the power supply is reliable.
- The extension line and feeder quality are poor or too long, so the bit error rate is high;
