Most chip manufacturers keep their firmware very close to the chest and from my anecdotal experience, a lot of that firmware is of a low quality; mush a smattering of shoddy chips together and you end up with really weird behavior.

FCC certs of a custom radio used with a bluetooth chip with a binary blob for firmware is the most painful thing I've ever done in my career...I think.
