Add check that the command buffer claimed in `bt_le_create_conn_cancel` is not `NULL`. Fixes a fault caused by providing the `NULL` buffer to `bt_hci_cmd_state_set_init`. Signed-off-by: Jordan Yates <[email protected]>
The extended advertising start procedure can consume both command buffers in a single API call, resulting in `bt_le_create_conn_cancel` being unable to claim a buffer to terminate the connection request. Increase the command count if both extended advertising and Bluetooth central are enabled in an application. Signed-off-by: Jordan Yates <[email protected]>
