CSR8645 Bluetooth 4.0 AAC APT-X Module / Baseboard

[tempos]

I haven't tried the battery reporting service. The trouble is these modules have ROM's, so cannot be flashed with different firmware. Certain features can be enabled/disabled by the PSKeys, but only if these features are actually part of the ROM mask - thats why for most 8645 modules you cannot just 'enable the I2S port' because the ROM mask doesn't use it.

With that said, if you can use AT commands, then it seems you have a different ROM from the rest of us (UART is disabled on every module I have).

The CSR 8600-series config tool, seems to be specific to headset profiles, so many not include options for battery service. Have you tried searching in PSTool for keys involving 'battery' ?

thanks for your reply. I'm not sure about i2c because I have only SPI on my pcb. I can't send AT Commands. it was question 'coz the easiest way to enable battery service is via uart. unfortunately there is no uart on my pcb, so I looking for a way to enable it via SPI

Regarding i2c: i found some pskeys in PSTool but can't check if it works
btw: have you seen this doc? http://www.52bluetooth.com/csr/adk2.5.1/adkdocs/CS-101505-UGP6PSToolUserGuide.pdf
point 2.1.2.1

Battery report works out of the box here (tested only with IOS). Parameters can be changed within the CSR8600 config tool (ADC-levels, ADC-input, etc.)

@Buriedcode,

if it's the same module as this:

CSRA64215 4.2 Stereo Bluetooth Audio Module support AVRCP A2DP APT-X CSR8645 | eBay

DAC outputs are routed and should be available. You may check if the DAC output is enabled.

A document called "CS-212778-AN-1 Headset ADK 1 Configuration PS Key Bit" might help.

for me it's disabled. I have bluetooth headphones based on csr8645
here is my battery section

would you be so kind to provide yours? so I could enable this feature for my module

Better use the attachments options in the advanced answer menu

I think GAIA support must be enabled. Could you provide a complete key-dump via PSTools?

found this article: How to send handsfee battery level indication to i... - Silicon Labs Community

but seems to be it's impossible to send at commands by SPI using PSTool or Configuration Tool

 

[doctormord]

Do you have HFP profile enabled?

All CSR modules i use provide battery level, even this from Sanwu (Combined with amp).

You may wanna look into the BTM625 modules:

https://de.aliexpress.com/item/BTM6...ule-BLE-4-0-4-2-I2S-TWS-APTX/32755318704.html

The CSRA64215 seems to be a CSR8645 on stereoids with working I2S.

I searched further and I think I want to use this module:

I'm sorry, but I don't speak chinese.

Changing a whole usr-key without knowing what's changed exactly isn't something I'd recommend at all.
