GPy - NB-IoT (Vodafone - Germany), didn't get it working

[BlackDuck]

Hello,

i try to get my GPy working with Vodafone NB-IoT working but i am stuck and i am unsure where is the problem.

With help of robert-hh i got some steps forward but i did get it attached, and the documention do not help

me.

First a bit over my equipment

1 x Vodafone NB-IoT datacard
1 x 1nce - 1nce.de NB-IoT which is a Reseller for German Telekom
1 x PyTrack 1.1
1 x Expansion Board 3.1
2 x GPy's one with limited Band support the other looks like this

lte.send_at_cmd('AT!="RRC:showcaps"')

== CAPS config =============================

  .TM8 TDD support        : false

I tried a lot but i didn't get it attached. If found this link https://forum.pycom.io/topic/4240/t-mobile-nb-iot-in-the-netherlands-solved/2 with a great diagnostic script.

OK

Maybe someone can see here the problem. This attempt above is with the Vodafone datacard.
