[Bluez-users] stalled ACL connection

[Bluez-users] stalled ACL connection

[Grahame Jordan]

Hi,

We are using a gumstix with Kernel 2.6.18gum with bluez-libs-2.24 and bluez-utils-2.24

Our device was setup as slave for PAN
PAND_OPTIONS="--role PANU --service GN --connect 00:15:83:C6:78:0f --persist"

This was connecting well with the BlueSoleil Windows BT Stack
However the BlueSoleil stack is fairly promiscuous and can trash other setting on a Windows machine.

We are using a 
Bus 006 Device 002: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)
which works with native WindowsXP SP2+ Bluetooth stack.

However the Windows stack requires that the PAN on our device is set to Master
PAND_OPTIONS="--role GN --service PANU --connect 00:15:83:C6:78:0f --persist"

Since it has been set to Master it does connect OK but it seems to consistently drop off after at least 12 hours of operation.

When I restarted the bluetooth stack I got this message.

Stopping Bluetooth subsystem:hci_acl_tx_to: hci0 ACL tx timeout
hci_acl_tx_to: hci0 killing stalled ACL connection 71:78:C6:83:15:00
hci_acl_tx_to: hci0 ACL tx timeout
hci_acl_tx_to: hci0 killing stalled ACL connection 71:78:C6:83:15:00
 pand dund rfcomm hidd sdpd hcid ttyS3.


Any help appreciated.

Thanks
