I tried a bunch of versions
But on these BT module does not see
CoreELEC-Amlogic.arm-9.2-nightly_20200220.tar
CoreELEC-Amlogic.arm-9.2-nightly_20200316.tar
CoreELEC-Amlogic.arm-9.2-nightly_20200413.tar
CoreELEC-Amlogic.arm-9.2-nightly_20200415.tar
CoreELEC-Amlogic.arm-9.2-nightly_20200423.tar
CoreELEC-Amlogic.arm-9.2.0-Generic.img.gz
Here on these sees the module, but does not connect
CoreELEC-Amlogic.arm-9.2-nightly_20200523.tar
CoreELEC-Amlogic.arm-9.2-nightly_20200525.tar
And here it works and connects CoreELEC-Amlogic-ng.arm-9.2-funhouse_2011.6-Generic.img.gz
I can use the box with a dongle (the audio is perfect) but if I blacklist the bt-uart module somehow rfkill blocks bluetooth on boot and I must log in and unblock it manually (despite bt-usb is loaded). The block runs in the very end of the booting process after autroun.sh can execute ‘rfkill unblock bluetooth’.
According to the dmesg, and also this thread, what you got is not a bluetooth adapter.
It’s also possible that linux doesn’t see it as an actual bt adapter. In any case it seems that it’s not supported.
@anon88919003 Hi, still no news regarding the BT for MT7668 ?
I found that there is a Linux version (Yocto Linux) supporting a board called # Pumpkin Evaluation Kit Smart Audio Edition that has the same MT7668 chip.
I tried to check, but my Linux source knowledge is limited so I didn’t know where to look so far.
That kit you mention uses a BT 5 version and as you may already know , there are a variety of modules that start with MT7668, most of which do seem to be of the BT 4.1/2 variety in boxes.
adamg did spend a lot of time on my box trying to get it to work but it seems that there is something missing that prevents it from working within CE.
As you may also have read elsewhere in the past couple of days, adamg is no longer around, so won’t be carrying things forward.
My advise right now is to get a cheap generic BT 4 USB dongle and just keep an eye out in case somebody discovers a workaround in the future.
I know that a BT dongle works, I’m using one.
The advantage of using the internal one is that I free a USB port, since I just have two and don’t want to use an USB HUB.
Makes the controversial point of having a small powerful box and them you have to have a bunch of external things to use it since everything inside doesn’t work, for that I buy a normal big PC or some other big machine.
@Compent Anyway, do you still have the driver or compiled code that adamg tested with you?
I like to take a look to see if I find anything extra.
I can’t cross compile properly the sources I have and found here since I don’t have the proper base PC and OS version or worst I’m doing something totally wrong and compile fails always with some error.
