Thanks a lot for that clarification.
I would like to add my experience about three options:
Effect strength - this is a percent of increasing bass
Mixing balance - this setting defined proportion between bass and hight\midle sound.
The crossover frequency - defines what exactly is a bass and what is a hight\midle. This is need for Mixing balance percent. In other words, if you set crossover frequency 150Hz and Mixing Balance 40%, the frequencies before 150Hz will play only on 40 percent, and frequencies after 150Hz will play on 60%.
Just in case, I'm not an expert on this, this is only my experience of configuring bass enhancing.
Thanks.
Any advice on using QCC_Tool? It's in Chinese and I'm struggling to make sense of it even with translators
Hi, I have only the dump in .xuv extension.
This is the link on it - Dump_QCC3031_Original.xuv — Яндекс.Диск
But I'm not sure that dump can help you.
My advice will depend on your goals of using this app. It works for me.
I hope this picture will help you.

I got one of these QCC3031 boards. Does anyone know which are the USB pins?
There's smaller solder holes on the left side labelled N, B, P, V, G. Just a random guess but could it be this?
N - USB_DN
P - USB_DP
V - VCHG
G - GND
I'm wondering if anyone has programmed this specific design before. I really don't want try a random guess and blow up my board.

About labeled holes on the board, in my case this is not working for me, I connected directly to the pin on the chip, the pictures on the first page can help you with that.
GND -> GND
Data+ ->USB_DP
Data- ->USB_DN
+5V ->VCHG
If you have a multimeter you can check contacts on the chip and on the lebeled hols.
From the picture you sent 1.27mm pitch pins are top to bottom
1 - NC
2 - D-
3 - NC
4 - VBAT
5 - D+
6 - VCC
7 - GND
I have the same board and I don't remember where I found it but I found a datasheet for the BTM331 and was able to trace out the pinout to confirm them. To be clear your connections between the two will be
USB QCC30XX
VCC 1 --> 6
D- 2 --> 2
D+ 3 --> 5
GND 4 --> 7
1 - NC
2 - D-
3 - NC
4 - VBAT
5 - D+
6 - VCC
7 - GND

Thank you. It works.
Unfortunately my board broke a few days ago. In the middle of listen to audio, it randomly died. When power is connected, one LED turns on for a second then goes out.
I wired up a USB cable and it is detected by the computer. I installed the drive and applied the unlock steps. It showed up in the NVS app. I was able to dump the firmware. The verify command and it was very flakey, failing to verify more often than not.
I tried to erase and reflash. But after erasing it is no longer detected by the NVS app. The USB devices still show up in Device Manager but nothing else works. So I guess it's really borked now. I noticed the firmware dump from my board is 28MB vs 57MB that German1212 posted earlier.
See reply 70 and 177 in the CSR675 thread.

Thanks. I was able to get Bluesuite from the dropbox folder.
I'm following the steps in the PDF and have created a file with 32 A 0 but TransportUnlock.exe is complaining:
Code:
==============================================================================
ERROR: Key of invalid length at line 1 of key file 'unlockcode.txt'
==============================================================================
FailedAny thoughts?

Hi i am new to this stuff. i am trying to build a diy headset wit the QCC5125 SOC from Aliexpress.
I have connected a PCM5102A to the I2S bus just to be sure i didn`t break it on the first try. It plays sound so i got a wireless headphone now. So my question is do i need to enable something in the adk configuration tool to set it to enable the dual microphone function? I stil need to get the components for the dual microphone circuit ( nothing connected at the moment ).

It seems unclear which boards are actually programmable at all. And which tools work with those that are programmable.
From what I can gather from other comments around the web, some variants have limited programmability. There's one post on 52bluetooth where the OP could not use any of the tools with their qcc3031. At least that's what it seems like from the translation.
The board I posted earlier burned out before I tried the USB connection so I don't know if it's not programmable because part of the chip blew up. These boards are too expensive to try random boards to find out which one can be programmed. Especially since they appear to break so easily.
