Hi chinnaobi,

Yes, AIrvantage data push stop is relate to data connection stopped.

```
Jul 17 09:01:30 swi-mdm9x28 user.warn Legato: -WRN- | avcDaemon[6782]/avcDaemon T=main | avcClient.c ConnectionStateHandler() 317 | Disconnected from data connection service, current state 1
Jul 17 09:01:30 swi-mdm9x28 user.info Legato: INFO | avcDaemon[6782]/avcDaemon T=main | avcClient.c BearerEventCb() 251 | Connected 0
Jul 17 09:01:30 swi-mdm9x28 user.info Legato: INFO | avcDaemon[6782]/avcDaemon T=main | avcServer.c ProcessUpdateStatus() 1364 | Update state: Session stopped

```

Do you have any idea why it get disconnected?  
Does restart the app RedSensorToCloud recover this?

To check further, maybe good to check below, before and after the stop:

> cm radio  
> cm data

And Legato API to get the disconnect reason:

> le\_mdc\_GetDisconnectionReason()  
> le\_mdc\_GetPlatformSpecificDisconnectionCode()  
> le\_mdc\_GetPlatformSpecificFailureConnectionReason()  
> [https://docs.legato.io/latest/c\_mdc.html#le\_mdc\_session\_networkItf](https://docs.legato.io/latest/c_mdc.html#le_mdc_session_networkItf)

Hope it helps.  
Thx
