[ctpelok77]

When running the example on Mac 11.6.1 with python 3.8.2, the following exception occurs the moment Dash is switched on.

Getting possibly identical error with python3.8.8 & running OS 13.4, did you bold those two lines ('forwarding' & 'CFRUNLOOP...') yourself? Also I'm generating this error kind of every time I run 01_hello_world.py, whether the Dash is on, off, or if I have bluetooth turned on or off (on my mac, having just toggled it to test).

First time I ran the script it asked for permission for Terminal to use Bluetooth, no other permission clues.

This is getting into stuff I have no experience in, but seems like a WonderPy-talking-to-Mac-OS-Bluetooth stack issue? Would be interested if anybody knows of any other workarounds/alternate bindings!

Got past the above error message from following this discussion: https://github.com/playi/WonderPy/issues/2

BUT! Just hit more weird errors. Nothing insurmountable, but was over my head in the details.

Then found this, https://github.com/IlyaSukhanov/morseapi. Is working for me on ubuntu with a python2.7 venv , pretty much just following instructions in readme.

If you guys want to try my fork of a fork from morse ~

https://github.com/mewmix/bleak-dash

Still a work in progress getting everything converted to async, but atleast you can use python 3

[jakesimonds]

Will check it out!

Was able to connect my apple-chip and intel-chip macs! Great instructions, was super easy on both machines

[mewmix]

Great news. Thank you for testing. I am working on porting over the sensors now so we can hook into different states like "Dash is on his side" or "Dash picked up" , or the holy grail, "is something infront of dash?" :)
