Quectel EP-06 with O2 LTE Connection Issue

Hello everyone,

I have installed the LTE kit with the Quectel EP-06 modem in my Omnia RTROM01. I am in Germany and my internet provider is O2.
So far everything works and the connection is always stable for about 24 hours.
Then there is probably a disconnection and reconnection of the provider and I no longer have a connection.
As soon as I manually restart the LTE interface, everything works again.

Does anyone have any idea what the problem is here?


There seems to be a problem with the “QMI Cellular” protocol.
I switched to the “UMTS/GPRS/EV-DO” protocol as a test and observed the time of reconnection. Everything works as it should.
The downside is that this protocol seems to only allow a speed of 25Mbit/s.
With QMI Cellular I had 50Mbit/s and more.
