void att_server_register_can_send_now_callback	(	btstack_context_callback_registration_t *	callback_registration,

Request callback when sending is possible.

Note

callback might happend during call to this function

Parameters

callback_registration	to point to callback function and context information
con_handle

void att_server_request_can_send_now_event

(

hci_con_handle_t

con_handle

)

Request emission of ATT_EVENT_CAN_SEND_NOW as soon as possible.

Note

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

Parameters

con_handle
