R1 Pro - AttributeError: 'NoneType' object has no attribute 'lower'

[vaylvn]

Hey there,

I know this project is more for the WalkingPad A1 however as you mention it seems the R1 Pro works under a similar setup.

Unfortunately I'm hitting this barrier upon trying to run

ph4-walkingpad-ctl --stats 750 --json-file ~/walking.json

AttributeError: 'NoneType' object has no attribute 'lower'

I'd assume this means it's unable to find the device however I'm not too sure what my options are. I've ensured it's not already connected to the phone so that shouldn't be the issue.

There is a bug in the code. In file ph4-walkingpad/pad.py modify line 83:

from:
if dev_name and dev_name in dev[i].name.lower():

to:
if dev_name and dev[i].name and dev_name in dev[i].name.lower():

Apparently some found bluetooth devices don't have name attribute, that's why the original code fails.

I have R1 pro too. same issue with bluetooth devices that have no name. the bluetooth device that works for me is named "RE". But it wont work very long.

Thanks @jure123 for pointing this out. I will fix it in the code and release a new version

[dolomitt]

FYI I cannot get the main walkingpad source code to work on Windows. asyncio wont let me do add_reader anymore.

ProactorEventLoop has the following limitations:
The loop.add_reader() and loop.add_writer() methods are not supported.

I can get the source code from belt_control jupyter file to work though with my R1 Pro.

pls try now v1.0.2
