Out Of Band (OOB) messages

Deprecation of Service Status callbacks

The Sigfox callback service is composed of several types and subtypes, please browse to the callback documentation for the full description.

This change only affects the Service Status callback subtype and will not impact core device data callbacks.

Please be advised of the upcoming changes to our Service Status callback service. We will be transitioning away from this service on the following timeline:

  • September 2026: creation of new Service Status callbacks will be disabled.
  • April 2027: the Service Status callback service will be fully discontinued.

OOB messages are transmitted periodically by devices. These transmissions are inherent to the Sigfox protocol stack.

They contain the following information about the device:

  • Device temperature
  • Battery voltage: VDD Idle and VDD Tx
  • RSSI

Repeater devices also periodically send OOB messages to the backend which contain battery level and statistics of repeated messages.

All these messages are automatically decoded by the Backend upon reception.

OOB messages are not taken into account in the daily uplink messages count.
