+# Qualification procedure

+# flash a qualifiaction dongle
+- To use a normal nRF5240 Nordic dongle
+- See https://bluekitchen-gmbh.com/bluetooth-pts-with-nordic-nrf52840-usb-dongle/ for Nordic nRF52 dev dongle
+- Install PTS Firmware Upgrade Software
+- Plug-in nRF52840 USB Dongle
+- Start PTS Firmware Update Software
+- If you click on 'OK', updating the bootloader will fail (the Nordic bootloader on the nRF52840 USB cannot be updated via DFU)
+- Close the software
+- Open an Explorer window and navigate to C:\Program Files (x86)\Bluetooth SIG\PTS Firmware Upgrade Software\tools and copy the file nrfutil.exe
+- Navigate to AppData\Local\PTSFirmwareUpgradeSoftware within your user folder and paste the nrfutil.exe into this folder
+- Note the file with the UUID128-like file name as you'll need it soon
+- Open a PowerShell via File->Open Windows PowerShell as a regular user
+- Reset the nRF52840 USB Dongle by pressing the smaller button (labeled 'RESET') to enter DFU mode
+- A red LED should start flashing
+- Run the nrfutil.exe with the .bin file (it's actually a ZIP archive) with the UUID128-like name
+- Or just press the TAB key: .\nrfutil dfu usb-serial -pkg be4d3ab8-9c98-408a-8be4-18acf4b32d28.zip -p COM4
+- Et voila, the nRF52840 USB Dongle can be used with PTS
+
+# PTS ixit prerequisites
+In BAP set 
+- Broadcast_ID=12
+- Broadcast_ID_2=13
+
+In CAP set 
+- TSPX_BST_CODEC_CONFIG=16_2_1
