4.

ATCN

It is used to quit configuration mode.

5.

ATDS

It is used to read or set 16-bit of targeted module. This command is only available in

transparent mode. When the targeted address is 0xFFFF in transparent mode, the module will

broadcast the data. If users hope that DZM5168M module still can send the data to the same

targeted address after next power-on, users can use command ATWR to save the parameter.

6.

ATCH

ATCH command is used to read the present wireless channel number. There are 16 channels

available. The modules in the same network must work in the same channel. The channel

number is compliant to protocol 802.15.4. The center frequency=2045+(CH-11D)*5 MHz.

Among which d refers to decimal.

7.

ATFR

It is used to reset the module. When DZM568 receives this command, it will be reset at once

without response.

8.

ATHV

The command is for reading hardware version of module

9.

ATID

ATID is used to read or set PAN (Personal Area Network) ID. The modules only can

communicate when their IDs are the same. Users need to execute ATRN command (ATRN 1)

and ATWR command if new PAN ID is set. When DZM5168M is powered on next time, the

network will be reset and the new PAN ID then comes into effect.

The PAN ID can be set to any value among 0x0000~0xFFFE. If the PAN ID is set to 0xFFFF,

different type of modules will have different reaction.

●

For Coordinator, it will choose one value among 0x0000~0xFFFE randomly as its

PAN ID when it is powered on.

●

For Router or EndDevice, they will search the PAN ID of ZigBee network and

change their PAN ID to the same and try to join this network after the modules being

powered on. If there are more than one ZigBee network, it will choose to join the one

with best RSSI.

When the PAN ID of modules are set to 0xFFFF, the actual PAN ID of DZM5168M after

joining a network can be read out by ATPI command. If the PAN ID is specified to any one

among 0x0000 ~ 0xFFFF, the values read out by commands ATPI and ATID are the same.

10.

ATMP

ATMP is used to read the 16-bit address of father node.
