Currently trying to get bluetooth working (amebad only).
I can at least get it to show in hcitool, but cannot get it up.
This is done via a variant of uart-tcp bridge.
It seems that some opcodes are not implemented.
Bluetooth: hci0: Opcode 0x0c52 failed: -56
And realtek library is built to support only LE mode, not BR/EDR(legacy).
Unsure if i'll manage to get it to work, but at least i'll report what i've done and if someone might figure out what to do in the future.
I should also note that this is done via hci_driver from Tuya rtl8721cs source.
Added after 2 [hours] 32 [minutes]:
I wasn't able to fix it in sdk code, so i had to adapt linux bluetooth driver.
I was able to get it running, but no tests were done.
But while i can somewhat control it via hcitool, bluetoothctl doesn't see it.
I can at least get it to show in hcitool, but cannot get it up.
This is done via a variant of uart-tcp bridge.
