Firmware, Application, and Settings Files
There are multiple levels of software and settings files contained on the device:

1. Modem software is flashed onto the cellular modem at the factory. This firmware controls communications between the modem and the cellular carrier. In the very rare event that this firmware needs to be upgraded, it will be performed by Positioning Universal.
2. Device operating system firmware manages the control of modules on the device and provides the operating environment for Applications. In the very rare event that this operating system firmware needs to be upgraded, it will be performed by Positioning Universal.
3. Applications are written in JavaScript and can be loaded to the device via the serial UART or OTA. Applications can be updated to add functionality or improve performance when opportunities for improvement are found.
4. Settings files are loaded to the device via the serial UART or OTA. Settings files contain the parameters used by the application to control tracking and other behaviors.

DMAN Server
A Device Manager Server on the Positioning Universal infrastructure automatically updates Applications and Settings files for groups of devices. When an update of the application or new settings are released, they are loaded into the DMAN server and assigned to the Groups of devices that are to receive the update. The DMAN server automatically updates devices to the latest assigned versions. In normal operation, devices “check in” to the DMAN server regularly to report their health, and to check whether they are due to get updates.
Device will take the updates either immediately if commanded via the “update” command, or during the next quiescent period, before entering Sleeping state.

UART Programming, Trace, and Commands

• In the factory and on a test bench, the serial UART connection is used to flash an image containing the root firmware, application, and default settings files using special factory software. Specific queries, commands, and debug tracing messages are also available over the UART. In normal operation, the UART is only used for debug, command, and tracing purposes. Custom applications may use this UART to communicate with accessories.
• The serial UART consists of RX, TX, and Ground signals on the 4 pin UART connector. Communications uses a TTL level of 3.3V. A supply of 3.3V is available on this connector to power a low power accessory (like a logger). NOTE: supplying 3.3V to the FJ2100 via this interface from a USB-TTL serial adapter will power the processor, but will not provide enough power for the cellular modem to work.
• To communicate between a computer and the device using the UART, it is necessary to have a serial terminal program installed on the computer. Several examples are Hyperterm and Realterm on Windows, and CoolTerm on either Windows or Mac computers. Communications is at 115200 baud, 8N1.
• The most common way to physically connect a computer to the device is to attach a USB-TTL serial adaptor to the 4 pin serial harness. Note that the optional Vdd wire (red) is NOT usually connected for basic communications. Examples of suitable USB-TTL serial adapters include those that incorporate the MAX3232 integrated circuit, or the CH340 chipset. Note that you may need to download and install drivers for these devices on a computer in order to use them. There are many different versions of these adapters available. Typically, the device that incorporate a crystal perform better. One version is available on Amazon from this link: Serial Converter adapter
• Once connected, trace information will be sent as ASCII data over the UART interface. This allows the user to monitor operation of the device and see how it responds to various occurrences, as well as see a report of GPS status every 10 seconds. Queries and Commands shown in the next chapter can be sent to the device from the computer and responses seen in the terminal window.

SMS Queries and Commands
The queries and commands shown in the following chapter of this guide can be sent by SMS to the phone number of the device, and responses will be sent to the phone number of the device used to send the query or command.

UDP Queries and Commands
The queries and commands shown in the following chapter of this guide can be sent by UDP to the IP and port of the device. Due to cellular carrier security features, these queries and commands are usually queued on the sending server, and sent immediately after the server receives a message from the device. In order to indicate that the UDP
Positioning Universal, Inc. – Confidential & Proprietary message is a command, it is necessary to prepend the equals sign = to the front of the command. For example, to send the agps command to a device via UDP, it is necessary to send it as =agps so that the device sees the = first and recognizes the following data as a command.

Queries and Commands

Queries and commands can be sent to a device via the serial UART, an SMS message, or via a UDP message over cellular. All queries and most commands will generate a response if successful that begins with the word PASS. If a command is not recognized by the device, it will respond with a message beginning with the word FAIL.

Queries
Queries request status information from the device, and the device responds accordingly.

Version
The device responds with the version numbers of the application and settings file and other information. An example response to the version query is:
PASS::version;app=3023 sett=3023 firm=3124 cell=4.3.1.2 [29492] imei=354196070019771 imsi=311480142180885

Example:
PASS::where; http://maps.google.com/?49.26445910000 ,-

settings
The settings command will respond with all values of the settings file in json format.

Commands
Commands force the device to take specified actions. They can be sent via SMS, a serial UART, or via the cellular data connection.

report,
The report command forces the device to send a regular event message with the event code specified in the command.
Eg. report,9 would force a report with event code 9.

reboot
The reboot command forces a warm boot of the main processor and sub modules of the device. The reboot will occur in 5 seconds to give the device a chance to send a result in command ack based upon sms or udp delivery. If comm fails then no ack may be received even though the device does actually reboot. The device reports a
WARM_BOOT message when it powers back up.

sms, ,
Send an SMS message with specified payload to specified phone number.

update
Checks latest versions of application and settings for a device on DMAN and if different than existing application and/or setting then start update.

bootin
Sends a boot checkin message to DMAN, which updates status and statistics for the device.

AT Commands to Modem Module
AT commands can be sent directly to the cellular modem module on the device using the command sendAT,
For example, send AT,CEREG? will send the command “AT+CEREG?” to the cellular modem.

NOTE: Sending AT commands to the cellular modem can change critical settings on the cellular modem and may interfere with its operation and block communications. This command is only to be used by developers familiar with the use of AT commands on cellular modems.
