How to make SX1272MBxAS and GPS Maestro A2035 work together ?

Hello

Here is a program for which the final aim is to take GPS coordinates from the maestro A2035, make some operation with them and then send it to another card with the SX1272MBxAS (this treatment is not makee right now).

My only problem is that when I execute a program which only take coordinates, it works, when I execute a program which only send variable by the SX1272MBxAS it works, but when I try to make this tasks work together (like in the picture at the top), I just read a message "Radio could not be detected".

So my program is stuck line 134 everytime I execute it, and I don't know how to resolve this problem.

Hi there, I do not have these components but from your description it looks like a collision between selected pins for GPS and pins used by the radio shield (SX1272MBxAS).

The radio shield uses the pin A0 for device reset but you use the same pin for a serial communication with your GPS.
