Hi friends . I am trying to communicate with my sim800l gsm to pin 8,9 to arduino nano , i can't . On 2,3 works fine , but i need 2,3 for interrupts. or can i use other pin exept 2,3 , and how, thanks .
From what I read at this webpage --
such is possible, since it's using SoftwareSerial( )
Assuming, given your lack of details, that this --
is how you have things wired
SoftwareSerial mySerial(3, 2); //SIM800L Tx & Rx is connected to Arduino #3 & #2
SoftwareSerial mySerial(9, 8 ); //SIM800L Tx & Rx is connected to Arduino #9 & #8
move the wire connected to 3 over to 9 and then move the wire connected to 2 over to 8.
I'm trying to get a reading "\nstatus=READY"on my serial monitor when gsm is connectwith to singl . on pin 2,3 works fine , on 8,9 i get the reading "trying to force boud rate"9600 "\nstatus=IDLE" why;
try 10 and 11
