new breadboard adapters

while I was playing with new BT modules I create few breadboard friendly adapters for them, I also sell these at tindie store, not for profit but to make programing and playing with these module easy so other can contribute to OSS comunity (libraries, HW designes, etc..)

• F-6188 based on BK8000L
• F-6888 based on BK3254
• BM20 module based on IS2020 from Microchip
• BM23 module based on IS2030 from microchip
• updated version for F-3188 module based on CSR8645
• update version for blk-md-spk-b based on OVC3860 chip

Updated adapter for blk-md-spk-b - OVC3860

update: buttons, mic jack

Module as is shipped from china, is not capable of calling (at least not on my S9, after picking up phone, phone will disconnect from module), but there is solution: - upload this PSkey data dump with this software, here is how-to connect it and how to change name also.

Libraries for BT modules based on OVC3860,BK3254 and BK8000L chips

while ago I created this libraries, for bluetooth modules based on chips:

• OVC3860 (blk-md-spk-b,S3860M-S,SX3868 modules) [1]
• BK3254(F-6888 module) [2]
• BK8000L (F-6188 module) [3]

Library for OVC3860 based modules

For more info about library for OVC3860 based modules check wiki where I wrote about PSkey configuration mode and how you can change name, pin using example provided with library.  Library also support fallback to PSKey mode when module is not supporting standard AT command for change name nad pin, but be aware this will restart module.
Library require getNextEventFromBT() function to be call periodicly from main loop.
 
List of functions is in README.md in repo.

All documents and SW which I use as source of knowledge (AT commands, PSKey config mode) are in this repository.

Library for BK3254 based modules

This library is less complicated, supporting only AT commands, some of them did not work for me, so ...

List of functions is in README.md in repo.

analysis of volume fix adapter from ebay by tomsad

so friend has problem with volume on his audi concert, I know what is problem, and also that there are at least 2 adapters on ebay which should fix this [1], [2] (second one is also here: [3])

second one is smaller and cheaper so I go for this one.

.... adapter arrived at postbox, so I was curious how it's works. So i take closer look at traces on PCB and realize that mcu is STM32, and is only grabbing SPI from display and send I2C to audio controller (TDA7342), so they recreate complete audio control stack, nice, lets check it how well it works ;).

 I made simple arduino sketch to get i2c data on this radio [4], and here are my observations:

input selector is not working,

changing bass/treble/fade/balance can by set different from what is showed on display, check my github for output from arduino i2c sniffer links to files [5],[6],[7] are from "modul from ebay/programatory.com" and file in link [8] is output of reprogrammed Motorola MCU which I buy like 3-4years back.

so, what to do? return it and try first one(from ebay) or implemented volume rewrite in my code??

so after while I write few lines of code to fix this, code is on my github [9]
schematics will be there in few days

BK8000L change name

- unsolder flash chip on module(in my case it was FT25H04 by Fremont Micro Devices, datasheet: [1])
- connect it to programmer supported by flashrom [2]
- download flashrom source code [3]*
- extract, compile
- download flash content, or download dump from my github repository [4]

./flashrom --programmer serprog:dev=/dev/ttyUSB0 --read BK8000L.flash

edit with favorite hex editor:

search for asci string BK8000L, change it, save and flash:

./flashrom --programmer serprog:dev=/dev/ttyUSB0 --read BK8000L.flash

 solder flashchip back on module, power it and enjoy ;)

UPDATE 2019

No need to desolder chip, using this CH341A adapter [this one], I succesfully read/write chip, only requiremet is reset of module to be puled to ground (Credit goes here).
