unpack requires a bytes object of length 10 #8

Closed tactmaster closed 5 years ago

tactmaster commented 5 years ago

Hello

I get the error unpack requires a bytes object of length 10

import sys, time, datetime
from pycalima.Calima import Calima

fan = Calima("my mac", "mypin")
currentState = fan.getState()

Any ideas?

What fan dom you have? There seems to be some differences between firmware versions.

If possible, provide the output from running cmdline.py with the scan flag -s.

I.e. something like,

sudo python3 cmdline.py -m your_mac -p "your_pin" -s

I have had this python code working before btw.

Thanks for the hint, you're correct. getState previously read 12 bytes (which the characteristic contains), but when going from handles to uuid a letter had disappeared from the unpack fmt. Do try the latest commits!

Sorry for forgot to get back you. That is great it working again very nicely. Thanks
