I am running the MicroMod Asset Tracker with the STM32F405 RGT6 and I am unable to get the AssetTracker Examples to connect to SARA.
For example AssetTracker_Example7_GNSSAntennaPower
This test fails to connect, while it is not required for the above test it is for future tests.
init: Begin module init.
sendCommandWithResponse: Command: E0
init: Module failed echo test.

Replacing the STM32 with the shipped update tool board and sending direct AT commands works.
I have seen similar posts but those were dealing with the AWS version.
The firmware version is 3.15.
