Greetings,
One query on the very useful eDRx notifications in NB-IoT mode (nRF9160 SDK running 1.3.1 FW, used with MoSh app) :
I have just noticed that sometimes when I change the eDRx settings (below example change : from PTW=2.56s to 10.24s) the Modem Sleep enter/exit notifications are no longer displayed by the SDK. Is this a known issue ? Or did we miss something ?
I have tried to unsubscribe then subscribe after the PTW value change, but UE still does not display seelp notifications anylonger.
Are those Modem Sleep Notifications only available for a subset of the eDRxcycle&PTW timer values?
