We don't have calibration code yet, so connection can be less
stable/slower. Unfortunately I won't start working on it for some time
as there are different issues I want to address first.

As for info about signal, it's possible we incorrectly parse headers
coming from firmware. I've to check this issue with my hardware, then
I'll be able to say sth more.
