Question
STM32WL LoRa Code
Hi,
I am new to STM32.
I am trying to implement LoRa Receiver and Transmitter code in STM32WL. I have tried to modify the Rx and Tx code using the Ping-Pong application code (subghz_phy_app.c) .
I have added my Transmitter code below, can you please review the code and suggest changes.
Also, how can I change the time duration of messages sent by the transmitter end node?
Rgds,
Frank
