* Function CalConnectParamTimeout * Description This function is called to calculate the connection parameter timeout. * Returns timeout

* Function l2cble_start_conn_update * Description start BLE connection parameter update process based on status * Parameters: lcb : l2cap link control block * Return value: true if successfully sending the request to peer device, else false.

* Function l2c_link_check_power_mode * Description This function is called to check power mode. * Returns TRUE if link is going to be active from park * FALSE if nothing to send or not in park mode

* Function l2c_send_update_conn_params_cb * Description This function send the update connection parameter callback to the uplayer. * Returns void

* Function l2c_link_send_to_lower * Description This function queues the buffer for HCI transmission * Returns TRUE for success, FALSE for fail

* Function l2cu_send_peer_echo_req * Description Build and send an L2CAP "echo request" message * to the peer. Note that we do not currently allow * data in the echo request. * Returns void

* Function l2cu_reject_connection * Description Build and send an L2CAP "connection response neg" message * to the peer. This function is called when there is no peer * CCB (non-existant PSM or no resources). * Returns void

* Function l2cu_send_peer_ble_par_req * Description Build and send a BLE parameter update request message * to the peer. * Returns void

* Function l2cu_send_peer_ble_par_rsp * Description Build and send a BLE parameter update response message * to the peer. * Returns void

* Function l2cu_get_conn_role * Description Determine the desired role (master or slave) of a link. * If already got a slave link, this one must be a master. If * already got at least 1 link where we are the master, make this * also a master. * Returns HCI_ROLE_MASTER or HCI_ROLE_SLAVE

* Function l2cu_send_peer_info_req * Description Build and send an L2CAP "info request" message * to the peer. * Returns void

* Function l2cu_reject_ble_connection * Description Build and send an L2CAP "Credit based connection res" message * to the peer. This function is called for non-success cases. * Returns void

* Function l2cu_create_conn_after_switch * Description This function initiates an acl connection via HCI * If switch required to create connection it is already done. * Returns TRUE if successful, FALSE if osi get buffer fails.

* Function l2cble_init_direct_conn * Description This function is to initiate a direct connection * Returns TRUE connection initiated, FALSE otherwise.

* Function l2cu_find_ccb_by_remote_cid * Description Look through all active CCBs on a link for a match based * on the remote CID. * Returns pointer to matched CCB, or NULL if no match

* Function l2c_is_cmd_rejected * Description Checks if cmd_code is command or response * If a command it will be rejected per spec. * This function is used when a illegal packet length is detected * Returns BOOLEAN - TRUE if cmd_code is a command and it is rejected, * FALSE if response code. (command not rejected)

* Function l2cu_send_peer_echo_rsp * Description Build and send an L2CAP "echo response" message * to the peer. * Returns void

* Function l2c_link_timeout * Description This function is called when a link timer expires * Returns void

* Function l2c_info_timeout * Description This function is called when an info request times out * Returns void

* Function l2cble_create_conn * Description This function initiates an acl connection via HCI * Returns TRUE if successful, FALSE if connection not started.
