Resource Busy Error during connection attempt with BLED112

[eteters]

On Mac, in terminal -

I am seeing an error when trying to establish a connection with a Muse 2016.

muselsl list results in

Traceback (most recent call last): File "/Users/evanteters/anaconda3/lib/python3.6/site-packages/serial/serialposix.py", line 265, in open self.fd = os.open(self.portstr, os.O_RDWR | os.O_NOCTTY | os.O_NONBLOCK) OSError: [Errno 16] Resource busy: '/dev/cu.usbmodem1'

I tried addressing the issue through using muselsl list --interface /dev/cu.usbmodem1
but this still gave an error. This time:

File "/Users/evanteters/anaconda3/lib/python3.6/site-packages/serial/serialposix.py", line 265, in open self.fd = os.open(self.portstr, os.O_RDWR | os.O_NOCTTY | os.O_NONBLOCK) OSError: [Errno 6] Device not configured: '/dev/cu.usbmodem1'

I'm running High Sierra 10.13.6, and using BLED112-V1 manufactured by Silicon Labs

I tried to find other processes accessing the same port but it seemed nothing was using it.

Thanks for the help!

This is an old issue with pygatt version 3, see: peplin/pygatt#159
There are two solution, either:
a. Upgrade pygatt > 4 pip install -U pygatt
b. Use the time.sleep(2) hack, as explain here: peplin/pygatt#159 (comment)
