Hi Charlie,

I have solved this issue by using nrf_modem_lib_shutdown() once the Modem firmware update successful!. Because LwM2M carrier also initializing the modem lib in NORMAL MODE which I have cross checked in lwm2m_os.c which was creating issues for our application to run after modem firmware update and hence 2 times reset were happening.

Thanks for your support.

Regards,

Chetan

Hi Chetan,

[quote user="Chetan Kale"]1. Can we perform modem FOTA update from AWS while LwM2M carrier Lib is present in the application ?[/quote]

I am not sure what you mean 'present' here. The Carrier library sends an event when it is about to begin to do FOTA. It is safe action as long as the application is not trying to FOTA after having received the Carrier library event indicating it is about to start FOTA by itself.

[quote user="Chetan Kale"]2. Do we need to use either of them in the application to perform modem FOTA ?[/quote]

Yes, use one of them at one time to avoid conflict action to MFW.

Best regards,

Charlie

Hi Charlie,

I know in asset tracker we have the modem FOTA support implemented using Lwm2m Carrier or AWS server. Here my questions are

1. Can we perform modem FOTA update from AWS while LwM2M carrier Lib is present in the application ?

2. Do we need to use either of them in the application to perform modem FOTA ?

Note: If I do not integrate LwM2M carrier lib in my application then I can perform modem FOTA using AWS without any issues and the logs are already shared while creating the ticket.

Thank you !

Regards,

Chetan

Hi Chetan,

The nRF9160: Asset Tracker — nRF Connect SDK 1.6.0 documentation (nordicsemi.com) supports FOTA from either Lwm2m Carrier or AWS server. You can refer to this sample for your application.

Best regards,
