Dear All,
We have implemented the communication procedure between a STM32F7691-discovery based device and the server according to the sample code of STM32CubeExpansion_Cloud_AZURE_V1.1.0.
Once the device make a connection to the server, it seems that the connection keep alive even after the data transfer is complete.
Because our device only needs to connect to the serer every 15 minutes, continuous connection is not necessary.
Actually, after the date transfer is complete, the connection seems to be is closed by the server (may be something like timeout).
We are not sure whether we need to close the connection after each data transfer by the device.
If we need to close the connection after each data transfer, we would likt to know how to close the connection.
Thanks in advance for your advice.
