I am trying to send GPS data using B-L072Z-LRWAN1. I use PingPong project and changed the PingPong_Process as follows.
static void PingPong_Process(void) {
Radio.Sleep();
memcpy(BufferTx, tempBuffer, sizeof(tempBuffer) - 1);
Radio.Send(BufferTx, PAYLOAD_LEN);
}
"tempBuffer" contains a portion of the GPS data. When I receive data on another B-L072Z-LRWAN1 and view it in TeraTerm, it appears to be capturing GPS data. However, data reception stops after a few minutes. Sometimes it stops after one minute, while other times it continues for about 20 minutes. I can send text data using same B-L072Z-LRWAN1 without problem. However, errors occur when sending and receiving GPS data.
