GPS data send server, stops after 1 day

[cityba]

@KaranRajPradhan I run the gps-tracker code, rewriting it a bit, and 24 hours after turning it on, the data transfer stops, the sim card goes, it rings. What could be wrong? why does it stop after exactly 1 day? is there any hidden function that causes this? release code also stops at 24 hours.Can anyone help?

@KaranRajPradhan - didn't we see and debug this too? Did we push our reconnect changes?

[cityba]

@tejpochiraju Can anyone help?

[KaranRajPradhan]

@cityba - which code do you mean by "gps-tracker code"?

@cityba We have noticed some issues with GPRS/GSM network disconnecting while running over longer period of time. The approach we took was to catch these network detachment/disconnect event and try to reconnect.

You can look at an example of that here

Hope this helps!

[cityba]

@KaranRajPradhan Then what should i modify on the me code?

[KaranRajPradhan]

@cityba Just add the code that captures the events as done here

• API_EVENT_ID_NETWORK_REGISTER_DENIED
• API_EVENT_ID_NETWORK_DETACHED
• API_EVENT_ID_NETWORK_ATTACH_FAILED
• API_EVENT_ID_NETWORK_DEACTIVED
• API_EVENT_ID_NETWORK_ACTIVATE_FAILED

And then call the appropriate reattach/reactivate function: https://github.com/IoTReady/a9_gsm_gps_library/blob/main/a9_mqtt_lib/src/mqtt_example.c#L40
