I know that there's nothing wrong with the speakers because I also have a laptop with a built-in bluetooth adapter (also F8, 2.6.25.4 kernel), and this has managed to pair with and them use the speakers without difficulty. I can also use l2ping between my USB adapter and my speakers, despite them not having paired: # l2ping 00:14:EF:00:20:05 Ping: 00:14:EF:00:20:05 from 00:0A:3A:7D:FF:80 (data size 44) ... 4 bytes from 00:14:EF:00:20:05 id 0 time 7.73ms 4 bytes from 00:14:EF:00:20:05 id 1 time 22.91ms 4 bytes from 00:14:EF:00:20:05 id 2 time 21.68ms 4 bytes from 00:14:EF:00:20:05 id 3 time 20.44ms 4 bytes from 00:14:EF:00:20:05 id 4 time 19.24ms 4 bytes from 00:14:EF:00:20:05 id 5 time 11.01ms ... However, this seems to be as much as I can do until they have bonded. (In fact, the only way that I could keep the connection alive long enough to strace the "auth" command was by using l2ping.) Does anyone have any suggestions for anything else to try, please? Cheers, Chris __________________________________________________________ Sent from Yahoo! Mail.
