TLS

OS3.1.0 and later

The first time the device connects to the cloud, it uses TLS communication.
The plan of the account at the time of connection establishment determines whether TLS communication is enabled or not, and if TLS communication is enabled or not. If it is not possible, then the communication will be in plain text afterwards.

The version of TLS used is as follows

  • TLS 1.2
