Audio dropouts over bluetooth during Wlan scan
I have recently acquired a bluetooth device which allows me to play audio from the N9 through my stereo (a logitech device).
It plays mostly ok except for dropouts on a fairly regular basis. I decided to watch the syslog ( /var/log/syslog ) to see whether there was any specific activity during those dropouts, and noticed that they coincided with the following messages appearing in the log May 4 21:17:05 (2012) wlancond[1763]: Scan issued May 4 21:17:07 (2012) wlancond[1763]: Scan results ready -- scan active So my question is: is there a way the music player can be made robust to other processes running on the system, like wlancond ? These dropouts are making the N9 fairly ineffective as a music player, and I had been hoping it might be possible to use it as a main loungeroom music player. |

All you can do is vote, get others to do so, & maybe add some useful ideas there. I doubt it'll make it into PR1.3 though, it's primarily a bug-fix release for the nastiest bugs. They barely have enough resources for them, let alone secondary ones & new features. And it's very unlikely there'll be a PR1.4 and PR1.5 :( |

well bluetooth and wifi uses the same antenna and frequencies, you cannot burn the candle on both ends. If you use the both actively at the same time, you cant except that it wont affect the other. Quite many products are using single antenna for wifi&bt functionality.
Increasing buffers would help, or disabling either bt or wifi. |

Can this be fixed or not? Simply Y or N? |
Re: Audio dropouts over bluetooth during Wlan scan
you can always stream over 3g and usbnet to bt. Streaming over wifi to bt will most likely cause problems sometimes.
I don't remember if there is config files for the buffers. Someone else most likely can comment on that better. |

It's unfortunate two antennas weren't used, hopefully management of the buffers can at least partially mitigate this issue. |

cant you just deactivate wlan?

Re: Audio dropouts over bluetooth during Wlan scan
also if you change /schemas/system/osso/connectivity/network_type/search_interval to 0 value, it disables the search scanning (default value 300 ie every 5 mins). Most likely that will be enough to fix the problems that scan caused.

You can use http://talk.maemo.org/showthread.php?t=81614 Gconfig GUI, or commandline with:
# gconftool-2 -t int -s /schemas/system/osso/connectivity/network_type/search_interval 0 |
