RC-RICK-868
Lora Radio Modem AT Command (LoRa Transparent Transmission Protocol)
RC-RICK-868 is a radio modem with UART interface usable with AT commands for long distance communication with LoRa
modulation (LoRa Transparent Transmission Protocol).
Working into European bandwidth : 868MHz
The hardware is based on the module RC-WLE5-868 designed by RadioControlli (STM32WLE5Jx based).
For more information and details, please refer to :
- RC-WLE5-868 datasheet (www.radiocontrolli.com)
- STM32WLE5JC datasheet (www.st.com)
CORE : STM32WLE5Jx
Operative Frequency bands : 868MHz.
Ready for use SMD mounting (13 x 14.5mm) - Metal shield.

QUICK GUIDE point-to-point LoRa connection
What is necessary ?
1) An Evualuatio kit RC-RICK-868-EV composed by N.2 Dongle USB
2) Download the application developed by RadioControlli using the following
WEB page.
Dongle USB
Receiving LoRa module
1) Connect the USB Dongle (Receiver) to a PC
2) Launch the application
4) Enter the serial port number
5) Open the serial port (baud rate 9600)
6) Prepare the module as RX
7) By pressing keys 1-6, send the following AT commands:
- AT+Freq=868000000 set frequency to 868MHz
- AT+BW=0 set Lora bandwidth to 125MHz
- AT+SF=9 set Lora spreading factor to 9
- AT+CR=4 set Lora coding rate to 4
- AT+PreambleLen=8 set PreambleLen to 8
- AT+RX
When the last AT+RX instruction is executed, the module will always be in receive mode.
Transmitting LoRa module
1) Connect the USB Dongle (Transmitter ) to a PC
2) Launch the application
4) Enter the serial port number
5) Open the serial port (baud rate 9600)
6) Prepare the module as TX
7) By pressing the 1-5 keys, send the following AT commands:
- AT+Freq=868000000 set frequency to 868MHz
- AT+BW=0 set Lora bandwidth to 125MHz
- AT+SF=9 set Lora spreading factor to 9
- AT+CR=4 set Lora coding rate to 4
- AT+PreambleLen=8 set PreambleLen to 8
By pressing the 6 key the "Hello World" transmission was carried out.
Reception OK.
