The Bluetooth config options are: Enabled, Pairing Mode and Fixed PIN Value. Bluetooth config uses an admin message sending a Config.Bluetooth protobuf.

informacja

ESP32 Devices: Bluetooth will be disabled if WiFi is enabled. The WiFi setting takes precedence.

Bluetooth Config Values​

Enabled​

Enables Bluetooth.

Pairing Mode​

Specify pairing mode.

RANDOM_PIN generates a random PIN during runtime. FIXED_PIN uses the fixed PIN that should then be additionally specified. Finally, NO_PIN disables PIN authentication.

Default Pairing Mode​

The default pairing mode will be determined based on whether the device has or does not have a screen attached to it during the first boot (or with a stale device state) unless manually configured via the Bluetooth config options.

  • Screen Attached: If your device boots up for the first time (or with a stale device state), and a screen is detected, the default pairing mode will be set to RANDOM_PIN. Should the attached screen be removed after the device has already been booted, the default pairing mode of RANDOM_PIN will remain unless manually changed to FIXED_PIN or NO_PIN. It is recommended the pairing mode be updated prior to removing the attached screen.
  • No Screen Attached: If your device boots up for the first time (or with a stale device state), and no screen is detected, the default paring mode will be set to FIXED_PIN with the default value listed below unless manually configured to a custom value.

Fixed PIN​

If your pairing mode is set to FIXED_PIN, the default value is 123456. For all other pairing modes, this number is ignored. A custom integer (6 digits) can be set via the Bluetooth config options.

Warning

It is strongly recommended that you change the default FIXED_PIN code on your device. Leaving the default code in place can pose a significant security risk.
