once, and the device has not joined a network, the Associate pin blinks a numeric error code to
indicate the cause of join failure. The number of blinks is equal to (AI value – 0x20). For example,
if AI=0x22, 2 blinks occur.
If the commissioning push button is pressed once, and the device has joined a network, the device
transmits a broadcast node identification packet. A device that receives this transmission will blink
its Associate pin rapidly for 1 second.
The following figures demonstrate these behaviors.

Associate
The associate pin can indicate the joined status of a device . Once the device has joined a
network, the associate pin toggles state at a regular interval (Δt). The time can be set by
using the LT command.
Associate
Device not joined
A single commissioning button press when the device has not joined a network that
causes the associate pin to blink to indicate the AI Code where : AI = # blinks + 0x20.
In this example , AI = 0x22.

(Remote Device)
A single button press on a remote device causes a broadcast node identification transmission
to be sent. All devices that receive this transmission blink their associate pin rapidly for one
second.
