On the ESP32S3 Sense, if I populate a program with a lot of Serial.print() commands, the program wont run if the USB cable is not plugged in and with the Serial monitor open.
I can work around this by disabling all Serial. commands thus;
#define DEBUG false //set to true for debug output, false for no debug output
#define DEBUG_SERIAL if(DEBUG)Serial
And then changing all the Serial.prints() to
The program is a working GPS tracker using an SX1278 LoRa module.
If I want to see the Serial.print() commands I just set DEBUG to true.
Is there away around this fix that would allow all the Serial.print() commands to stay in place as is ?
