XALO — LEDs Silent Mode

Enables or disables silent mode for all Antares LEDs. When silent mode is ON, all device LEDs (red, green, and yellow) remain permanently OFF regardless of modem connection status, GNSS quality, or any other operational state. When silent mode is OFF, LEDs follow the normal behavior.

The silent mode state is persisted across reboots.

Notes​

  • Silent mode is stored in the device database and survives power cycles and firmware restarts.
  • While silent mode is ON, the LEDs will not indicate modem connectivity, GNSS fix quality, or any other system status.
  • The default value on a fresh installation is 0 (silent mode OFF).

Defaults and Limits​

  • Default: 0 (silent mode OFF).
  • Valid values for A: 0 or 1 only. Any other value returns error code 7 (incorrect parameter).
