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.
How often do you switch between M1 and NB1 when there's no coverage?
Every time no coverage is present. I have this problem at "Treriksrøysa" as well, where Norway, Sweden and Finland meets.

How often is this? every 5 minutes, 10 minutes, 60 minutes? If you switch between functional mode (CFUN=1) and flight mode (CFUN=4) more than 30 times over 1 hour, it is seen as a denial of service, and the modem will lock you out. Unfortunately, there is however a recently discovered issue with modem v1.0.1, where this counter is not reset after 1 hour, where a manual reboot will then clear this in the modem, and you should then get to attach to the network again. This issue will be addressed in the next version of the modem.
Kind regards,
Håkon
THank you, useful information!
The device is scheduled to send every hour. So what your're saying, is that for these devices, 30 reconnects is killing the device, and in order to get it working again, a manual reboot is required?

It is a 3gpp feature to avoid hammering a network (which is seen as a denial of service vector), where we unfortunately have a bug in modemfw v1.0.1 that does not clear this after 60 minutes if performing several cycles of CFUN=4 and CFUN=1. A reset (soft-reset or hardware reset) will solve this, or issuing a CFUN=0 before turning the modem back on again.
