Topic: Arduino UNO | ICOMSAT v1.1 SIM900 GSM Module (Read 2690 times) previous topic - next topic



I am trying to use UNO with ICOMSAT v1.1 SIM900 GSM Module .  I am currently trying with this https://github.com/jgarland79/GSM_Shield library . I have set the rx,tx pin as 2,3 and have also connected uno to external supply but i am not getting any response from the GSM module . I send a simple AT command but get no response.I think UNO is not able to communicate with the GSM . What change should i do ? Another Library?



did you try to set the tx rx pin of 7 and 8


did you turn it on? can you upload the sketch? remove the shield before uploading


Make sure you have at least 7V / 2A on the Arduino + Shield. The module is power hungry. There's another library, by openelectronics (or something like that) which works well with this shield. Just google it.
