Please forgive if this is a noob question.
So I picked up this blue tooth module. By team pie called the TDM157. It uses a AP8064 chip I will try and include the data sheet for this.
My issues. The chip seems to have many functions that have not been used by the guy who developed the PCB.
The other issue is that the response is not flat. I don't think this is a bad thing. But if I connect via blue tooth and send it a freq sweep. And I connect my scope to the output I see that the voltage change with freq.
How hard would it be for me to make a custom firmware. Where I can use all the special functions of the chip and maybe develop a custom eq.
Visited the site of the company who makes this chip. Did not see any SDK.
Lets assume this chip does not support a SDK for custom firmware what chip is there out there with the best SDK and support.

Use Analog Devices ADA1701. Look it up lots of such chips with multiple button support and encoder and I2s input with plethora of DSP options , could even make a dedicated bi amp with digital sources
Also the software for this is graphical so you pull blocks
Also there are from 10 to 14 I/0 which can be switched or pots or encoder depends on the chip and what you want. There are ready boards and you can design one.

You would be lucky to get the IDE and register set for the AP chip as it’s a Arm chip with dsp in built
The chip you Mentioned is MVSilicon chip used by Arylic and they have a PC Software which which they could do some custom curves on the customer side. So look up Arylic webpage if you can find the tool. May or may not work since the team pie module may not have used the USB interface and have a pre fixed.
You could have googled

Explore the forum, use translator might find some info.

They will not give a licence.
The manufacturer says he can do changes but I have to order 50 units. So back to the drawing board lol.
Thanks I will look into the chip set you mentioned.
Yes the teampie unit does support usb and you can update the chip code. With fresh firmware. Not sure if its locked in or not.
But their web site does show two firmware updates.
It would be nice if the added an option for flat response and one for bass boost. Not asking for much.
I like the unit cause it has a large display and built in FM. As well as you can record FM. Plus its really cheap compared to trying to build something from scratch.

You get what you pay right.
You may look in this forum - for AD1701 or google mini dsp and go that path so may be you will get the tone section , cross overs and interface via one chip.
As for the FM and Bluetooth you can always build it around the dsp and have a micro controller controlling all three.
