+Mesh Profile Bluetooth® Specification
+
+3.7.6.1.3 Periodic publishing
+A model may be configured to send status messages periodically regardless of whether the state has changed or not. This is done by using a Publish Period (see Section 4.2.2.2). When the Publish Period is set to a non-zero value, unless specified otherwise by a higher layer specification, a status message shall be published at least once every Publish Period. When the Publish Period is set to 0, the status messages shall only be published on a state change when enabled.
+
+3.7.6.1.4 Publish retransmissions
+When a new message is being published by a model instance, all pending retransmissions of the previous message published by the model instance shall be canceled, and the model instance shall retransmit the new message as specified by the Publish Retransmit Count and Publish Retransmit Interval Steps states.
