What is not supported are also custom parameters and custom codecs; including hardware mSBC support. Last year I started this thread because kernel blocks usage of AuriStream codec in any form (software or hardware). And AuriStream is supported by many bluetooth headsets and should have better quality than CVSD codec. > we spend a lot of time enabling WBS on oFono > but it looks like people are now trying to come with their own > solutions and complaining about lack of WBS is not really justified > since the combination of BlueZ + oFono has been in use by the car > industry for years but desktop folks has not been interested in a > proper HFP solution so instead we have modem manager, network manager, > etc, which doesn't even cover all desktop use cases properly as you > are experience first hand here. Apparently all people who are periodically writing me private emails are not interested in car industry, but are ordinary desktop / laptop users and ofono is not ready for these use cases and are not going to fix it. I guess that Aleksander and Andrew too are desktop / laptop users and not from car industry.
