I have the following problem.
I am working with a LoRa Ra-02 Module, and I am using it as a transmitter receiver, the receiver has the task of moving 6 motres DC of 12V, for this I am using a 16-channel relay module, and with the relay modules, I am creating H bridges that allow me to control the rotation of the engine
Well, the relay module, to activate its coils, takes care of 12v, so the module has its own source of 12, likewise, the motors have their 12V power supply and the arduino is connected by the computer
What happens is the following, the relay module, without connecting the motors, works perfectly, it is controlled by the Arduino with the LoRa and without losing data, however, once the power source of the motors has been connected, and when trying To control the motors, the LoRa module loses connection and I don't explain myself because, if the module has a part of power that isolates the Arduino. It should be noted that these are linear motors.
Idk if it is problem of the code or the LoRa, maybe should be the relay module.
The code i am using is the next:
#include <Arduino.h>
#include <LoRa.h>
#include <SPI.h>
#include <Wire.h>
int rly1 = 14;
int rly2 = 15;

{
