CH (Operating Channel)
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)
Set or read the user network identifier.
Devices must have the same network identifier to communicate with each other.
Devices can only communicate with other devices that have the same network identifier and channel
configured.
Setting the ID parameter to 0xFFFF indicates a global transmission for all PANs. It does not indicate a
global receive.
Parameter range
0 - 0xFFFF
Default
0x3332 (13106 decimal)
DH (Destination Address High)
Set or read the upper 32 bits of the 64-bit destination address. When you combine DH with DL, it
defines the destination address that the device uses for transmissions in Transparent mode.
The destination address is also used for I/O sampling in both Transparent and API modes.
To transmit using a 16-bit address, set DH to 0 and DL less than 0xFFFF.
0x000000000000FFFF is the broadcast address. It is also used as the polling address when the device
functions as end device.
Parameter range
0 - 0xFFFFFFFF
