STM32 MCUs Wireless

Do anyone have sample code of using UART or USB CDC by modifying Ping Pong (STM32CubeExpansion_LRWAN_V2.1.0)application in B-L072Z.

I'd like to use a STM32WL55 or B-L072Z-LRWAN1 as a 'beacon sniffer' and 'packet sniffer'.

I'm busy debugging the RF conditions around my LoRaWAN installation.I get a lot of variance in both RSSI and SNR (+-10dB/+-6dB) and am trying to find it's source.In the absence of an SDR and other equipment, is it possible to read and report RSSI an...

I want to configure B-L072Z-LRWAN1 Board-1 to transmit data through USB device(CDC) and another board-2 to receive data through LoRa, if board-2 after receiving data, if it send some data then board-1(which is connected to PC) have to receive it.

Between Board 1 and Board 2 data exchange should be done through LoRa and data exchange between Board 1 and PC should be through USB. It would be very helpful if someone help with this.

How to enable AT commands on P-NUCLEO-LRWAN3 sensor board

I am using P-NUCLEO-LRWAN3 and I have re programmed the sensor board (NUCLEO-L073RZ + LRWAN_NS1) using the STM32CubeExpansion_LRWAN_V2.1.0.I am getting TxTimeout and JOIN FAILED and I can’t execute any AT commands?

Resolved! Where can I get the new firmware that I must update the board with?

I bought the P-NUCLEO-LRWAN3 STM32 Nucleo starter pack for LoRa and it says that if the NUCLEO-LO73RZ board's serial number is within a certain range, which it is, the board must be updated with a new firmware before use. However, the link provided o...
