[SOLVED] problem with bluetooth - pair but doesn't connect

[TheOldPresbyope]

android 10 xiaomi phone and a tablet galaxy note 10.1 2014. my pc is windows 10. tv samsung tizen os

i am not sure that the problem is the connecting devices because it a lot and totally different.


on the other side I am the first that I have this problem with moode.

So??

The point is that moOde's existing code results in a BT connection with the devices available to the testing team. Here, for example, is what bluetoothctl says of my iPad connection

Code:

[Pixel 3a]# info D0:D2:B0:DB:13:78

and similarly for my iPhone and Google Pixel 3A phone.

If the moOde code doesn't result in a connection with other devices we need to know what those devices are if we are to have a chance of understanding what's different.

The only one of your list that I have a possibility of borrowing is a Bluetooth-equipped Win10 laptop and I don't know when I'll get to it.

I have one, just tried it, works OK.

@georgew21 given the large number of devices that won't connect to your RPi, I'd recommend borrowing a replacement RPi if you can and seeing if that can connect with Bluetooth when running moOde. I know you say that picoreplayer works, but there is still scope for a hardware issue that is not exposed by picoreplayer, and is exposed by moOde.

[georgew21]

it's difficult to find another RPi.

Searching google I found out that the problem with connecting some devices to bluez is known and it has already suggested the solution to "trust" before the connection of a device.

Why with picoreplayer I hadn't problem and with moode I had it's uknown for me. I don't know if moode use latest version of bluez. in picoreplayer I had updated bluez
