Dear all, I have taken the bluetooth code with BLE changes (net/bluetooth and include/net/bluetooth) from http://git.infradead.org/users/vcgomes/linux-2.6.git/tree/refs/heads/le-l2cap to my 2.6.35 kernel and built the kernel. and also built bluez 4.84 on ubuntu 10.10. Tried testing GATT with the gatttool that is available with the bluez. gatttool --primary -b <bd-address> gives me the following error: hci_acl_tx_to: hci0 ACL tx timeout hci_acl_tx_to: hci0 killing stalled ACL connection F5:61:0D:28:00:08 hci_acl_tx_to: hci0 ACL tx timeout This error occurs in both cases where there is an existing ACL connection and no connection. Other commands related to LE through hciconfig and hcitool work fine, like hciconfig hciX leadv, hcitool lescan, hcitool lecc, hcitool ledc. But it seems like the GATT connection is not happening and thereby not fetching me the required data. Please let me know if anyone has come accross this problem and how to get through this. Please see the log (hcidump) of the Master BT device below followed by the hcidump of Slave (GATT Server).
