LEAT EchoStar Terminal BSP

This reposistory contains the Arduino Core for LEAT EchoStar Terminals.

This example demonstrates how to use use the GNSS and Echostar network for tracking application
This code can also be used to test Echostar AT commands, GNSS UART and I2C sensors (BME280 and KX025)
The terminal try to get a GNSS fix and send to Echo network its position + sensing information

From the USB Serial Port, command supported are :

$BME : Read BME280 and provide Temperature, Humidity and Pressure
$KX : Read KX023 and provide accelaration along X,Y and Z
$RESET : Reset to initial state, can be use to exit from GNSS mode
$GNSS : Start GNSS mode, print every 5s the log from GNSS module
$NMEA : Start GNSS mode and print NMEA log
$LORA : Start LORA mode and bridge to EM2050 module. AT command can be used with EM2050 (AT+JOIN for example)
$setEU868 : Set EM2050 for Terrestrial LoRaWAN in Europe
$setMSS : Set EM2050 for Satellite LoRaWAN MSS supporting Echostar Mobile network
$dl : Provide EM2050 downlink parameters
$pwr : Provide EM2050 Tx power, it is usefull with Adaptative DataRate in Activated
$SENDLORA : Send a LoRaWan packet with board sensor value
$PERIODIC : Toggle the periodic mode (send LoRaWan message every 3mn)

If no usb is connected to the terminal, the code will periodically transmit a LoRaWan packet to the network. No sleep mode is implemented, limiting the terminal's lifetime with a battery.
