Description
Node discovery operates like other XBee devices and not like the
Legacy 802.15.4 module. This means the following:
1
Node
Discovery

0
1. A directed ND request terminates after the single
response arrives. This allows the device to process other
commands without waiting for the NT to time out.
2. The device outputs an error response to the directed ND
request if no response occurs within the time out.
The module operates like the Legacy 802.15.4 module, which has
the following effect:
1
1. When the expected response arrives, the command
remains active until NT times out. (NT defaults to 2.5
seconds.) This prevents the device from processing any
other AT command, even if the desired response occurs
immediately.
2. When the timeout occurs, the command silently
terminates and indicates success, whether or not a
response occurred within the NT timeout.
Default
0
CH (Operating Channel)
This command applies to the XBee/XBee-PRO S2C 802.15.4 RF Module.
Set or read the operating channel devices used to transmit and receive data. The channel is one of
three addressing configurations available to the device. The other configurations are the PAN ID (ID
command) and destination addresses (DL and DH commands).
In order for devices to communicate with each other, they must share the same channel number. A
network can use different channels to prevent devices in one network from listening to the
transmissions of another. Adjacent channel rejection is 23 dB.
The command uses 802.15.4 channel numbers. Center frequency = 2405 MHz + (CH - 11 decimal) * 5
MHz.
Parameter range
0xB - 0x1A (XBee)
0x0C - 0x17 (XBee-PRO)
Default
0xC (12 decimal)
ID (Network ID)
This command applies to the XBee/XBee-PRO S2C 802.15.4 RF Module.
Set or read the user network identifier.
Devices must have the same network identifier to communicate with each other.
