My third Serial port was using AltSoftSerial.h and was set at 9600 baud. The second Serial port was virtual using SoftSerial.h and was set a 57600 baud.
The first Serial port was hardware and was used for software debugging and AT command responses. Yes like this nasty ugly annoying character: �Īll things aside, I’m not going to get into depth regarding why this occurs on a lower theoretical level which for those of us who do know it involves system timers, interrupt handling, processor utilization, etc.Īt an attempt to mitigate loss of property I decided to make a GPS tracker with an Arduino Nano and an A7 module. Get rid of the gibberish from receiving/transmitting via your virtual soft serial ports on your Arduino Nano.
