If you are using the 6.1.18 kernel firmware, you can start it on usb, indicating that it also supports writing to emmc

Bluetooth installation, in armbian-config

To turn on the led, execute armbian-openvfd 14 to see the displayed results
https://github.com/ophub/amlogic-s9xxx-armbian/blob/main/build-armbian/documents/led_screen_display_control.md

Post the results of the following three commands, and I record them in the list

cat /boot/uEnv.txt
cat /etc/ophub-release
ls -l /boot/u-boot*

Right now I'm using microsd to boot, it can booted from USB also. So, it is able to write to emmc?

About bluetooth, I was able to install and when I checked using 'bluetoothctl' to gather some info about the BT using "list" it shows blank.

About LED, it shows the display correctly. Thanks.

And this is the last information you asked.

I didn't find any bluetooth instructions for WP6330 in the kernel source code.

Take a picture of the front and bottom of the box. You can see the specific name or model of the device.

Do you have Android system for this device? Share a download address.

Last week I was discussing the wifi on facebook group, and he give me this link of the chip. https://wikidevi.wi-cat.ru/AMPAK_AP6330, wifi BCM4330, BT BCM40183.

This this the detail model displayed on android.

I am unable to take picts the bottom of the device because it got ripped off when I played around with it, but I will ask someone who has the same device.

I dont have the android firmware file. But the android firmware is still intact in the emmc.

There is no firmware for this Bluetooth at present, if you find it, you can add it. The Android driver cannot be used.

I added this device to the options list, share 503/504 with h96

I think the chip is detected and initialized, but it just can't show the chip and use it via 'hcitool dev' or previously with 'bluetoothctl' command.

This is not the driver of your chip

Well, that's so unfortunate then. Oh yeah, 1 more question. A while back ago I was doing a backup of the emmc using openwrt-ddbr command while I was using OpenWRT. The backup went successfully. I was wondering if somehow I softbrick the device when I play around to install armbian/openwrt and then using that android backup to restore it, will it fully restore the android firmware?

Hey, I got the android firmware from my group. I have not tested it but my folks say that my device has the share the same with H96 Max X3. Well if I reference it with your model database IT IS h96 max x3. I want you to archive this firmware to preserve the file.

Okay, thanks for sharing. I will transfer this firmware here:

I think the chip is detected and initialized, but it just can't show the chip and use it via 'hcitool dev' or previously with 'bluetoothctl' command.

I have the same problem on my TX3-H ((QZ)4/64) same ap6330 i tell you if you can find 5.9 kernel version will run everything from the start, but the moment i do apt update it will not work anymore. I tested it like 40 Times i even broker 2 old de sdcards trying different distros, but I'm starting at Linux so i accept that my knowledge is rather limited but i also want to make the bluetooth work, can anyone help?
