Using latest SDK release LTS_03_2024_Ref02 and MQTT protocol
When setting the PROV_OPTION_TIMEOUT option, if the client time outs after a call to Prov_Device_Register_Device, it is not able to register when calling Prov_Device_Register_Device again with the same handle.
Is this the expected behaviour? I would expect a new call to Prov_Device_Register_Device would reset the current timeout and start trying again.
Those are the logs when calling Prov_Device_Register_Device while disconnected, then it time outs, and when trying to call Prov_Device_Register_Device it immediately returns the same PROV_OPTION_TIMEOUT error.
