+++AT loop, SIM800L, Arduino UNO #38

Closed piter1235301 closed 3 years ago

piter1235301 commented 4 years ago

Hello, I have a problem connecting because I get +++ AT all the time. I saw a similar problem on this page: _https://github.com/elementzonline/SIM800_MQTT/issues/15_ but it doesn't really help.

  1. I tried this program: _https://github.com/chandankumar1/temperature_logger/blob/master/thingspeak.ino_ ,and all commend give me feedback OK - so i thing SIM800L and Arduino UNO it's ok.

  2. I tried connect SIM800L to SERIAL PIN (0, 1) and SOFTWARE PIN (10, 11) - with no result.

If you are using SoftwareSerial interface with the GSM MODULE replace all mySerial with Serial and vice versa GSM_MQTT.cpp except for the extern SoftwareSerial mySerial; at line no 13

I tried this also, but same result... but maybe i made some mistake in code? I would be grateful if you could send the correct code...

Anyway i tried this with another module SIM800L and with Arduino nano... Same situation...

What i can do next?

Best regards.

easy. use software serial

tcampos123 commented 3 years ago

I have the same problem, how can I solve it?

MuhammedImdaad commented 3 years ago

either use software serial. or don't interrupt the serial line mainly the TX line.
