linux - hciconfig -a Connection timed out (110) , bluez, btusb -

i experiencing issue on raspberry pi.

after while of python programme running, seems 1 (or more) of bluetooth adapters "lock up" , hciconfig -a output: : connection timed out (110)

root ~ # hciconfig -a hci3: type: br/edr bus: usb bd address: 5c:f3:70:61:ca:d6 acl mtu: 9000:8 sco mtu: 64:1 running rx bytes:5315773 acl:178107 sco:0 events:287995 errors:0 tx bytes:487424645 acl:527773 sco:0 commands:13454 errors:0 features: 0xbf 0xfe 0xcf 0xfe 0xdb 0xff 0x7b 0x87 packet type: dm1 dm3 dm5 dh1 dh3 dh5 hv1 hv2 hv3 link policy: rswitch sniff link mode: slave take can't read local name on hci3: connection timed out (110)

the problem seems manifest more when multiple adapters used.

the project working on involves using multiple (and single) usb bluetooth adapters obex-push files phones. python programme next things:

1.automatically detects adapters - #hciconfig -a 2.configures them - #hciconfig cmd 3.inquires devices - #hcitool -i inq 4.obex force files on (possibly simultaneously other threads , other ) - bluez dbus

some info system:

any ideas/or suggestions?

is there newer version of btusb? looked, came empty handed

note: of linux newb (though learning) =-)

ps: these forums seem suggest similar may have been fixed: https://bbs.archlinux.org/viewtopic.php?id=183411 https://bbs.archlinux.org/viewtopic.php?id=183038 referenced problem appears atheros adapter chipset , using broadcom chipset. also, appears latest version of linux can rpi 13.13 headers , linux-raspberrypi 13.12
