the eventual goal would be to make my own boards with this chip as it seems to be available, or another if i need.

Are the AT commands specific to the program, or are they generic?

Hello, everyone! Can anyone contribute to making a port for Jieli microchips? I believe it's possible since I've already written minimal code to boot the chip. The MicroPython firmware only takes up 60KB, plus 40KB for the SDK files. However, I don't yet have the knowledge to port it without the SDK, as the SDK conflicts with MicroPython, making it unoptimized.

Hi, Ive done alot of reading here, great work. I purchase modules from amazon that work well for my application, I would like to add and change a few things to them.
The chip is an AC6955F4. Id like to change the ssid name, have an input to mute, and an output that a device is connected or better that a song is playing. Im pretty sure
mute is possible, but havent found the latter.
Hello, as a rule, not all SDKs implement external amplifier control. But it is quite simple to implement.
All SDKs have the DAC_MUTE function, it refers to the built-in DAC, and it can be modified by linking the GPIO to it.

Hello, thanks for the support. I was able to finally get the keys and get into the chip, I am trying to compile my own with the sdk, however I am stucked. I read the instructions and I am trying to find a way to resize it to make it compatible for the AC6969a chip. any help?

Hi!
Do you mean AC6969a2?
If so, you have 256KB flash.
1 - Need to disable all other audio decoders/encoders. Only SBC and MP3 (and wtg if using prompt sounds)
2 - Disable all other features like BLE/BT/RCSP_app background and more in the SDK.
3 - Need to check and configure prompt voices. What type and weight used.
The chip has 256KB flash. But in fact it is about 220k (because + bootloader and cfg)
All this information you can find in orig sdk. And in sdk there is this DOC - AC696N_2M_flash配置说明, here about lib for 2M (256k) flash.

thanks for the answer, i translated the doc and inserted the library, is this the file where I can disable all the above settings? apps\soundbox\board\br25\board_ac696x_demo\board_ac696x_demo_cfg.h.
Thanks in advance

Right. And Choise that config in "board_config.h"
I make simple step by step instruction for 695/696 here Усилитель 2.1 на TPA3116 и bluetooth на AC6955F.

The problem I'm having with the AC696X SDK is that the volume is too low. In the original firmware, the sound is loud even at the lowest volume on my phone

I followed your advise I was able to resize it but it ask for a license at the end any help on that?

Thanks, finally was able to upload the compiled firmware, i followed the 696 optimization instructions but the chip is showing in the blutooth list but does not connect.

in code blocks, when rebuilding i get alot of warnings and 2 errors. mostly "not defined, evaluates to zero". Not having any luck finding a solution. Any ideas?
