Migrating Issues from 1.7.0 to 2.7.0 SDK

[Kirolos Sedra]

Hello, I am having issue to migrate a working project based on Azure IoT Hub Application code from 1.7.0 to 2.7.0, I have resolved all errors associated with changing the SDK, but after building it does not give the original functionality. 

I am using Nrf 9160 to program a fanstel(BLE+LTE) Gateway, and there is a sort of integration between BLE and LTE application codes. The LTE Application is the one developed and flashed using VS Code in SDK 2.7.0

Hi,

I am having issue to migrate a working project based on Azure IoT Hub Application code from 1.7.0 to 2.7.0, I have resolved all errors associated with changing the SDK, but after building it does not give the original functionality. 

Can you describe in detail how the sample lost its original functionality? What is expected and what do you currently see? Do you get any errors?

Best regards,
Dejan

Hi, the functionality is Red: Gateway On
Green light: connection to cell tower established
Blue light: connection to cloud is established.  We are using Azure IoT hub example from 1.7.0 SDK, and we modified it and what we use to authenticate azure is a device ID and SaaS token.

The expected was: When I solve the issues of migration(errors) and flash the new build, I was expecting to see the same functionality, but it keeps at green stage, trying to establish connection. The used SIM is hologram. 

Is there a way to debug step by step to know the reason it actually fails? 

we are using an Nrf board to program a fanstel BLG840F gateway.
