I bought two STM32 Nucleo-L073RZ pack boards with expansion LoRa boards. I downloaded from STM32 site the example projects for board and I tried to run project for LoRa called PingPong. This project should start the communication between two boards. I unsuccessfully tried the PingPong project under IAR and also under Keil. It did not work, maybe problem in synchronization. At the beginning it works, but it fails after a some time.
I would like to ask anybody of simple source code STM32 with LoRa to run communication between two boards, simply receiver and transceiver.
