Sleep
mode LED status Meaning
0 On, blinking The device has power and is operating properly
1, 4, 5 Off The device is in a low power mode
1, 4, 5 On, blinking The device has power, is awake and is operating properly
7 On, solid The network is asleep, or the device has not synchronized with the
network, or has lost synchronization with the network
7, 8 On, slow blinking
(500 ms blink time)
The device is acting as the network sleep coordinator and is
operating properly
7, 8 On, fast blinking
(250 ms blink time)
The device is properly synchronized with the network
8 Off The device is in a low power mode
8 On, solid The device has not synchronized or has lost synchronization with
the network
Diagnostics support
The Associate pin works with the Commissioning Pushbutton to provide additional diagnostic
behaviors to aid in deploying and testing a network. If you press the Commissioning Pushbutton once,
the device transmits a broadcast Node Identification Indicator (0x95) frame at the beginning of the
next wake cycle if the device is sleep compatible, or immediately if the device is not sleep compatible.
If you enable the Associate LED functionality using the D5 command, a device that receives this
transmission blinks its Associate pin rapidly for one second.
I/O line monitoring
I/O samples
The XBee SX 868 RF Module supports both analog input and digital I/O line modes on several
configurable pins.
Pin configurations
The following table provides typical parameters for the pin configuration commands (D0 - D9, P0 -
P2).
Pin configuration commands include the following parameters:
Pin command parameter Description
0 Unmonitored digital input
1 Reserved for pin-specific alternate functionality
2 Analog input (A/D pins) or PWM output (PWM pins)
