hey i was using sim800l library, it is working fine but recently i want to send command to the chip for which there was no function in the library
the problem is that i dont want to change the original library and want to send that command using my main code file but when i write
SIM.print(F("AT+CMGD=1,4\n\r"));
It gives error of
'SIM' was not declared in this scope
i also tried using
SIM800L::SIM.print(F("AT+CMGD=1,4\n\r"));
but it also gives error of
'SIM' is not a member of 'Sim800l'
how can i send command in my main code file
