Connecting Physical Device to IoT Central
Hi,
I am trying to connect Raspberry Pi 3 to IoT Central using C language, however I am not able to see the telemetry data coming from device to IoT Central.
I then tested the same C code with a newly created IoT Hub and connected the raspberry pi. The IoT Hub is receiving the telemetry information successfully. So it means that the C code is working fine on device. It's just that my device is not able to send messages to IoT Central. Please note that I am using the correct Connection String in the C code to connect with the IoT Central.
Has anyone encountered this and any direction to fix it.
Regards

Ahmad-KAISPE Beyond the app itself you are developing, there are several things I recommend you look into. Networking issues like MQTT or AMQP ports being closed, System time not setup properly (which will prevent TLS connection establishment)...
