nRF9160 and network handover

How do we enable network handover when crossing a national border? Now it seems we have to manually reboot the device when crossing the border.

Hi,

 

How do we enable network handover when crossing a national border? Now it seems we have to manually reboot the device when crossing the border. 

 Is this related to roaming when crossing the boarder, or when crossing the boarder and going back again?

 

Kind regards,

Håkon

Any border crossing. The unit on test wnt silent going from Norway to Sweden. Telia has opened for LTE-M roaming, so rebooting the unit manually works on the Telia network.

Do you have any logs or debug info that might give an indication on what has occurred? Crossing boarders should be handled by the modem. Is there a specific routine that is running if the link is lost? Do you fall back on NB1 if M1 coverage is gone?

Kind regards,

Håkon

Sorry, no logs yet. If the Cat-M1 connection is lost, it tries to reconnect by toggling between Cat-M1 and NB-IoT

How often do you switch between M1 and NB1 when there's no coverage?
