int att_dispatch_client_can_send_now

(

hci_con_handle_t

con_handle

)

can send packet for client

Parameters

handle

void att_dispatch_client_request_can_send_now_event

(

hci_con_handle_t

con_handle

)

Request emission of L2CAP_EVENT_CAN_SEND_NOW as soon as possible for client.

Note

L2CAP_EVENT_CAN_SEND_NOW might be emitted during call to this function so packet handler should be ready to handle it

Parameters

void att_dispatch_register_client

(

Dispatcher for independent implementation of ATT client and server.

Parameters

packet_hander
