Gudipudi Ramana Kumar 44ed0c60ba samples: bluetooth: Increase number of buffers for avoiding deadlocks ... The central_multilink sample issues various API calls (in particular because it does some from the bt_workq("BT RX WQ")) this results in a deadlock since there are not enough HCI command buffers available, this is causing deadlocks on hardware that do not support BT_HCI_ACL_FLOW_CONTROL. Below is the flow where assert is observed: bt_hci_le_enh_conn_complete() -> bt_conn_connected() -> connected() callback -> start_scan() -> bt_le_scan_start() -> set_random_address() -> bt_hci_cmd_send_sync: opcode 0x2005 -> Controller unresponsive, command opcode 0x2005 timeout with err -11 Since the start_scan is called from the callback and BT RX WQ thread, the command buffers are still not available for the system work queue to process the hci commands it has to send out for starting the scan. By adding additional buffers this deadlock can be avoided. Signed-off-by: Gudipudi Ramana Kumar <ragudipu@silabs.com>		2025-05-05 10:57:33 +02:00
