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
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
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.
When receiving a packet, the device check this after the preamble ID. If you are using Original
equipment manufacturer (OEM) network IDs,
0xFFFF uses the factory value.
Parameter range
0 - 0xFFFF
Default
0x7FFF
MT (Broadcast Multi-Transmits)
Set or read the number of additional MAC-level broadcast transmissions. All broadcast packets are
transmitted
MT +1 times to ensure they are received.
Parameter range
0 - 0xF
Default
3
