//SENDER // It is a helmet that contains a sensor for gases, vital signs in the body, GPS , and a
temperature that transmits data via Lora connecting to arduino nano.
//RECEIVER// arduino nano contains Lora to receive data from sender.
I'm having trouble locating. The location does not appear correctly
also the ID it does not appear correctly it should be W001 but it shown sometimes W262, W81
This is the code below for sender and receiver.
