Not sending SMS while moving about sim800l

I feel like this could have been a power issue. I'll close this now.

hello buddy. Maybe the problem is the bearerProfile, try to activate when is moving, or try to deactivate it using the functions : activateBearerProfile(); or deactivateBearerProfile();
i don't think that the problem is the reset pin.

@cristiansteib doesnt activateBearerProfile and deactivateBearerProfile only get called in updateRtc? Because i'm not calling that.

@DarkN3ss61 yes, is used for establish communication with the tower.. so, try to activate and use with this configuration activated, just to see if behavior change

I got it working. I think it was the delay 100ms that was in the send SMS. I changed that to _buffer=_readSerial(); then it seemed to work no problem. Also I added a few other things into it like deleting a single SMS etc

Perfect, i will going to see more deep the behavior of sms.. thanks !

Opps, scratch that. It made it better but still happens when I'm going 100kmh. Works fine around 50kmh now though

The problem is solved for you?

Kind of. But I have been messing with the sim 800 models for a few years now (even made a site out of the https://temp-sms.org) and I know that power is a big issue with these. They need to have the exact voltage and enough amps to handle them or you will have a bad time. Before I was just powering it with 5v over usb. And that would have been the issue. I cannot confirm and the project I was working on with this issue no longer exists, so can't test there. But I am sure it's a power issue.
