Working with Sim 808 #23

Closed himanshu-hearthacker closed 4 years ago

himanshu-hearthacker commented 7 years ago

Hello I am using this library with sim808 (GSM+GPS), I am able to send data when i send any constant string but when i want to send GPS data, library doesn't publish GPS data. It probably disconnects TCP connection on running (CGNSINF=0) command. I tried to make TCP connection again but it doesn't work. Sometimes i am unable to get the GPS data when TCP connection enables. Is there any way i am able to send GPS data when TCP connection alive, I don't want to disconnect TCP connection to get GPS info and then again re-establishes TCP connection again. to send GPS data.

I am also working with SIM808 to get an MQTT connection. Could you share your code? I have tried many different libraries but with no success. I was able to get to work the Adafruit MQTT (io.adafruit.com) but I want to use a different MQTT broker. Thanks!

Hi guys. Any update on this issue? I have made a working prototype but there is a problem, it works fine in the start( for some time) and even publishes the location to mqtt broker but then disconnects and rarely connects back. I am getting socket disconnect error. -using pubsubclient and TinyGSM libraries.

The library is working in Transparent mode. So disconnecting and reconnecting GPRS frequently is not advisable.
