I installed via pip. While doing wble-central scan this error returned. `

File "/home/pi/Src/env/lib/python3.11/site-packages/whad/ble/profile/advdata.py", line 192, in from_bytes limited_disc = ((ad_record[0] & 0x01) != 0)


IndexError: index out of range
Segmentation fault

It looks like a faulty advertisement record caused this error (flags record with no data). This failed because of the wrong check we made before parsing the record data.

Allright, I've fixed the bad check and added some unit tests to avoid any regression. You can test if this fix works by cloning the main branch and giving it a try, or you can just wait for a new release (coming soon).
