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

The LT command defines the blink time of the Associate pin. If set to 0, the device uses the
default blink time (500ms for coordinator, 250ms for routers and end devices).
Diagnostics Support
The Associate pin works with the commissioning pushbutton to provide additional diagnostics
behaviors to aid in deploying and testing a network. If the commissioning push button is pressed
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. If the Associate LED functionality is enabled (D5
command), a device that receive this transmission will blink its Associate pin rapidly for 1 second.
The following figures demonstrate these behaviors.
