Hello ,
I have designed a sim800c module . It has sufficient current and connects to network every time . Also the call and sms work fine. but my problem is that it might not be getting the response every time so it just hangs.
I have used a while loop so that the next command is not send before the earlier response is received. I think it is getting stuck there.
I call multiple numbers and send sms to the same (this works fine). It exactly hangs when all the sms and calls are done after which I return to my homescreen to show signal strength .
Please suggest some solution. I don’t have any problem with the call and sms feature its just the response.
Thanks in advance
We can retry only if the call or sms was not received . My problem is that the call gets connected but the while loops doesnt end. I am attaching my code please let me know if I am doing something wrong. Thank You
