Define device?

The bluedot python library will/should run on machines running Linux with a Bluetooth backend (e.g. bluez). e.g. it would run a laptop running Ubuntu.

@martinohanlon Can confirm.

we are using imx8m mini som with a yocto build. installed bluedot using pip3 install bluedot. installation worked successfully. but when we run the example code it shows the following error

File "/root/test.py", line 2, in bd = BlueDot() File "/usr/lib/python3.9/site-packages/bluedot/dot.py", line 844, in init self.start() File "/usr/lib/python3.9/site-packages/bluedot/dot.py", line 1175, in start self._server.start() File "/usr/lib/python3.9/site-packages/bluedot/btcomm.py", line 351, in start self._server_sock = socket.socket(socket.AF_BLUETOOTH, socket.SOCK_STREAM, socket.BTPROTO_RFCOMM) AttributeError: module 'socket' has no attribute 'AF_BLUETOOTH'

please help me know if any supporting libraries or packages are missing.

thanks for the reply

AttributeError: module 'socket' has no attribute 'AF_BLUETOOTH

I am pretty sure this is because the build of Python that is being used hasnt been compiled with the relevant bluetooth "extensions" - I am being vague here because this isnt an area of expertise for me.

@InfictionLabs,

I agree with Martin that this is likely to a lower level dependency that isn't there. Yocto tends to be very basic by default.

You might want to check that BlueZ is installed correctly and up and running:

service bluetooth status

You can also check that you can scan and connect to a device with the Bluetooth command line tool:

bluetoothctl

You can check that Bluetooth sockets is in Python with the following couple of lines.

import socket
s = socket.socket(socket.AF_BLUETOOTH, socket.SOCK_STREAM, socket.BTPROTO_RFCOMM)

Once those lower level things are in place there should be a good chance that BlueDot will work as expected.

any packages that we installed or build through yocto showed "module 'socket' has no attribute 'AF_BLUETOOTH" error.

Yes, I am pretty sure that is because Python has been built without bluetooth support.

[martinohanlon]

I was looking at something else and came across this issue on another project including some instructions for building Python with Bluetooth support - it might be helpful for you.

I am going to close this issue as the root cause is not a fault with bluedot. If I can provide any further advice I am happy to.
