AT commands

MAC/PHY commands

The following AT commands are MAC/PHY commands.

CH (Operating Channel)

Set or read the operating channel devices used to transmit and receive data. The channel is one of
two addressing configurations available to the device. The other configuration is the Network ID (ID
command).
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 can only communicate with other devices that have the same network identifier and channel
configured.
If using Original equipment manufacturer (OEM) network IDs, 0xFFFF uses the factory value.
Parameter range
0 - 0xFFFF
Default
0x7FFF

RR (Unicast Mac Retries)

Set or read the maximum number of MAC level packet delivery attempts for unicasts. If RR is non-
zero, the sent unicast packets request an acknowledgment from the recipient. Unicast packets can
be retransmitted up to RR times if the transmitting device does not receive a successful
acknowledgment.
Parameter range
0 - 0xF
Default
0xA (10 retries)
