The fact is that these 2 modules communicate with my microcontroller (Mega2560 PRO (embed) CH-340G / ATmega2560-16AU from RobotDyn) on serial ports.
Ultimate gps : 10-9 RX TX
LoRa: 13-14 RX TX
What happens is that the last of the 2 modules I initialized in my Setup will work in the rest of the code, but not the first module.
I did several tests to identify the problem and i'm sure it comes from that.
For example if I initiate the GPS before the Lora, the Lora will work but the gps and vice versa.
I think I should use the.listen() function, but being a young arduino amateur I don't yet know how to use this function correctly.
Help wouldn't be a refusal.
Here is my code: (Gps init first before LoRa, gps not working. If i do the opposite init, Gps work)
