XML Data Exchange: Secure Mode, No PIN
1. As step 1 start-up is described already in Section 3.5.1.2, "XML Data Exchange", only the
subsequent steps are demonstrated here.
2. As the device is configured to Secure Mode without PIN, the provisioning service sends a
request to switch to Secure Mode (bootstrapping) including certificates and secure-port
number.
