Network detach occurs during nrf9151 OTA

[john.liu]

Hi:

Use nrf9151, ncs v2.8.0.
What should be done when PDN_NETWORK_DETACH occurs during OTA using fota_rownload_start?

Hello, 

Can you please provide full application log and modem trace from the device when issue occurs?

Thank you!

Kind regards,
Øyvind

Hi:

It's very difficult to appear, I'm not sure if I can capture it.

Then I'm afraid it will be more difficult for us to help debug this issue. Please provide more details and information. 

Edit: In practice: when your pdn_event_handler_t callback receives PDN_EVENT_NETWORK_DETACH, all active PDN contexts are effectively lost because the device is detached from the network, and your application should handle re-attachment / PDN re-establishment accordingly.

Kind regards,
Øyvind
