RYUW122 AT COMMAND GUIDE

THE NOTIFICATION OF USING AT COMMAND

The RYUW122 can set as role of “ANCHOR” or “TAG”. The distance value will be output through ANCHOR, and the data transmission can be bidirectional.
First you must use the AT+MODE command to set the module as ANCHOR or TAG.
Use “AT+NETWORKID” to set the UWB network group. Only those that set with the same NETWORK ID can communicate with each other.
Use “AT+ADDRESS”to set a unique Address.
Use “AT+CPIN”to set the UWB network encryption password. Only those that set with the same encryption password can be decoded correctly.
If you want to transmit data to ANCHOR from TAG, You must use AT+TAG_SEND command.
If you want to transmit data to TAG from ANCHOR and obtain the distance, You must use AT+ANCHOR_SEND command.
When TAG is set to the parameter of “AT+TAGD” for power-saving purpose, the “AT+TAG_SEND” and “AT+ANCHOR_SEND” command under the ANCHOR must match the RF duty cycle of TAG.

AT Command Set

It is required to key in “enter” or “\r\n” in the end of all AT Commands.
Add“ ? ”in the end of the commands to ask the current setting value.
It is required to wait until the module replies +OK so that you can execute the next AT command.

AT Test if the module can respond to Commands.
