Tried a lot of things to get my Sara R410M connected.
Using the serial passthrough sketch from http://support.sodaq.com/sodaq-one/sodaq-sara-r410m/ I can pass AT commands but after a short period (about 5 seconds) the device does not respond anymore.
I tried the example from Examples->Sodaq-nbIOT->test udp (and the other). Monitor: Initializing and connecting... ;FAILED TO CONNECT TO MODEM;Sending message through UDP
Does anyone have a short example script for connecting (to t-mobile)?
Or does this indicate a problem with the modem?
