FYI, your firmware wiki does not include the command “AT+POWR?” Query TX power. Also the wiki does not include “AT+SDUR?”. Both are obvious I guess, but probably better to include them since you include all the other AT+…? commands.

A couple of small English points in the same wiki:

“The AT command only effected when the BLE not connected by any cellphone.” should be:  
“AT commands can only be used when the BLE is not connected to any cellphone or other device.”

“Run AT+RESET to make the command affected” should be:  
“After using the AT+ROLE command to change the role, you must then execute AT+RESET to put that change into effect.”

Thank you very much for your mention. I’ve corrected these at [our wiki](http://wiki.aprbrother.com/wiki/Firmware/ZeroBeacon#Commands_for_ZeroBeacon_2.2.1).
