ATRE

This command is used to restore the factory settings of the module. The execution of this

command will result in the loss of network and might affect other information such as PAN

ID, 16-bit address, etc.

20.

ATRN

ATRN is used to read or set if the module resets the network connection at next power-on. If

the parameter is 1, DZM5168M will research the network and apply for joining it when it is

powered on next time. It means the information including PAN ID, channel, 16-bit source

address might be changed after restart.

21.

ATRR

It is to set or read the repeat times of air transmission when it fails. Users can use ATWR to

store this parameter into the memory.

22.

ATSC

ATSC is used to set or read the channel which will be used for searching. The parameter is a

16-bit value. Each bit is corresponding to one channel. If the bit value is 1, it means this

corresponding channel will be searched. If it is 0, this channel will be omitted.

Table 17: Bit vs Corresponding Channel Number

For example, if the parameter is 0x0008, the corresponding binary is 0000000000001000b so

the bit3 is set to 1 and corresponding channel 0x0E will be chosen. If there are more than one

bit are set to , the Coordinator will choose one as working channel but for Router or

EndDevice, they will search the multiple channels till they join in one of them.

Users need to execute command ATRN to make the new parameter of command ATSC come

into effect at next power-on of modules and use command ATWR to save the parameter into

the memory.

23.

ATSH

ATSH is used to read or set the high 32-bit address of IEEE 64-bit address. The 64-bit

address of each module is assigned by the RFIC supplier NXP Semiconductor and it is

unique on the earth in order to avoid the disorder of Zigbee network. Therefore it is not

recommended for users to change it. To set the 64-bit address with 0xFFFFFFFF can restore

the address to the factory default setting. The new address comes into effect at the next

power-on after executing ATRN and ATWR.
