Using Azure IoT Module clients

[dsilva-vd]

Hi,

This is a question on best practices using the NX Azure IoT API. My application is a cellular BLE gateway and my azure client uses module clients to represent each BLE sensor device. What is the recommended call pattern to connect each module client?

Do I make multiple calls to nx_azure_iot_hub_client_initialize() and nx_azure_iot_hub_client_connect for the device client and each module client?

I am using the sample_azure_iot_embedded_sdk_with_retry example. Does the thread stack size have to be increased per extra client that is connected?

Thanks!

Hi @dsilva-vd You are right, if you making multiple connections (device connection and module connections), you may need to make multiple calls to initialize() and connect() as below. For the stack size, I do not think you need to increase it, but you are able to run your sample for verification, if it works, no need to increase the size.

nx_azure_iot_hub_client_initialize(iothub_client1);
nx_azure_iot_hub_client_connect(iothub_client1);

nx_azure_iot_hub_client_initialize(iothub_client2);
nx_azure_iot_hub_client_connect(iothub_client2);

Thank you @bo-ms. I followed you advice and that worked. I am running into a separate error which I'll create a new ticket for.
