Time synchronization for nodes in a wireless personal area network (wpan)

A method comprising:

• receiving a first message, via an advertising channel, from an advertising node of a wireless personal area network (WPAN), the first message comprising an advertising message and a message identifier;
• receiving a second message from a timekeeper node of the WPAN, the second message comprising the message identifier of the first message and timestamp information identifying a time the second message was received by the timekeeper node;
• calculating a time offset value for a clock circuitry with respect to the advertising node, the time offset value comprising a difference between a time the first message was received by the receiver circuitry and the timestamp information of the second message;
• and
• adjusting the clock circuitry based, at least in part, on the time offset value.

An apparatus of a wireless device, the apparatus comprising:

• receiver circuitry configured to receive a first message, via an advertising channel, from an advertising node of a wireless personal area network (WPAN), the first message comprising an advertising message and comprising a message identifier;
• message generation circuitry configured to generate a second message comprising the message identifier of the first message and timestamp information identifying a time the first message was received;
• and
• transmission circuitry configured to transmit the second message to a scanner node of the WPAN.

A non-transitory computer-readable storage medium that stores instructions for execution by one or more processors to perform operations to:

• receive a first message, via an advertising channel, from an advertising node of a wireless personal area network (WPAN), the first message comprising an advertising message and comprising a message identifier;
• generate a second message comprising the message identifier of the first message and timestamp information identifying a time the first message was received;
• and
• transmit the second message to a scanner node of the WPAN.
