At first, I believed ACL stands for 'Asynchronous Connection Less' But I just read the BT_Core_v1_2 Specification that sais ACL is Asynchronous Connection Oriented (page 118 of 1200 / Architecture page 42 of 82) So, what is it? I have read books and internet articles that said ACL is connection less. Are they all wrong or am I totally messing up something? PAN uses the bnep protocol layer. Is bnep based on rfcomm? I think not, because I don't need to load rfcomm.o when using pand. But looking at the figure from http://www.rvs.uni-bielefeld.de/~heiko/bluetooth/bluetooth.pdf (page 6) you can get this idea. (From http://www.holtmann.org/linux/bluetooth/) (There are some other sources, too) What about the three error connection modes. Is it right that they are determined by packet type and so there is no way to turn it on / off ? (using pand for example / which paket types does pand use?) Because some papers speak about optionally error correction (ARQ) Data rate: Whats the data rate of a pand connection? I measured a data rate of 60-65 kbyte/s one way 30-35 kbyte/s the other way. The way I understand the Spec. (page 274 of 1200) that would be above the limits. 60 kbyte/s = 480 kbit/s is greater than the symmetric rate of 433 kbit/s but 30 kbyte/s = 180 kbit/s is greater any of the asymetric data rates. Whats my failure? Thanks for any clarity and de-confusion. -- Regards, Christoph Torens ------------------------------------------------------- This SF.net email is sponsored by: IT Product Guide on ITManagersJournal Use IT products in your business?
