Establishing module-to-module communication in Azure IoT Edge

So there are mainly 2 ways:

1. using internal routes
2. using direct methods

Regarding the blog which I have provided, is there any Azure documentation where I can see how to use these SQL commands(specially to put data into a database and how to query them)?

Hello @Pritam Chanda ,

Azure IoT Edge also supports a C2D communication mechanism named Direct Methods. Here we see just SQL queries over the SQL connection.

An alternative SQL call is seen here. This is easily rewritten in other languages like C#.

Notice you need to open the port (using the container create options) to make the Sql Edge database accessible, especially when connecting from outside Azure IoT Edge (like from another machine).

Actually my main end goal is to confirm that the modules are able to communicate with each other. So for that purpose, I need to confirm that the data sent from Simulated temperature sensor is present inside the SQL Edge by creating a Database and then ingesting the data into the SQL Database.
