0x07 is value for NRF24 status register, 1M data rate, highest gain (0db)
0504030201 is pipe address

Installation

This device does not need any driver on Windows 7/8, it uses driver usbser.sys that is already included with Windows. Only file that is needed is the INF file (a text file) that describes device's VID/PID and driver to use. Manufacturer package came with lot of noise, so we cleaned it, also it seems to be removed from internet, we keep the copy - you can find both INF file and original package below.

Unzip RFCOM_64.zip, open Device Manager, find WWW.AI-THINKER.COM device, right-click and select "Update Driver", then "Browse My Computer", then navigate to folder with unzipped RFCOM_64.INF file, then Next. It will complain about unsigned driver, select "Install Anyway" on Win7 or use this tutorial to install unsigned driver on Win 8.1

In the end you should get COM port for each XD-81. To test, we installed two XD-81, used TeraTerm and opened two TeraTerms, one for each COM port. When typing in one window, characters should show in the other. If channel is changed (you can use Paste function), communication breaks until you change channel in second window.
