From: Luiz Augusto von Dentz <luiz.von.dentz@xxxxxxxxx> Usually after pairing the source will attempt to connect and create a stream, but it may never send AVDTP_START command as it is not playing anything. In the meantime the local endpoint may attempt to acquire the transport, but since it was the remote side that opened the stream instead of sending AVDTP_START the code now wait and eventually timeout. To fix this now instead of just waiting the remote to send AVDTP_START the code will attempt to send the command if nothing is received after a small timeout (1s). --- v0: Only tested against MW600 which was the original cause of introducing wait logic. audio/avdtp.c | 25 ++++++++++++++++++++++--- 1 file changed, 22 insertions(+), 3 deletions(-) diff --git a/audio/avdtp.c b/audio/avdtp.c index 041abc3..d6f9682 100644 --- a/audio/avdtp.c +++ b/audio/avdtp.c @@ -93,6 +93,7 @@ #define ABORT_TIMEOUT 2 #define DISCONNECT_TIMEOUT 1 #define STREAM_TIMEOUT 20 +#define WAIT_TIMEOUT 1 #if __BYTE_ORDER == __LITTLE_ENDIAN @@ -1068,8 +1069,7 @@ static void avdtp_sep_set_state(struct avdtp *session, break; case AVDTP_STATE_OPEN: stream->starting = FALSE; - if ((old_state > AVDTP_STATE_OPEN && session->auto_dc) || - stream->open_acp) + if ((old_state > AVDTP_STATE_OPEN && session->auto_dc)) stream->idle_timer = g_timeout_add_seconds(STREAM_TIMEOUT, stream_timeout, stream); @@ -3647,6 +3647,19 @@ int avdtp_open(struct avdtp *session, struct avdtp_stream *stream) &req, sizeof(req)); } +static gboolean wait_timeout(gpointer user_data) +{ + struct avdtp_stream *stream = user_data; + struct avdtp *session = stream->session; + + if (avdtp_start(session, stream) < 0) + error("wait_timeout: avdtp_start failed"); + + stream->idle_timer = 0; + + return FALSE; +} + int avdtp_start(struct avdtp *session, struct avdtp_stream *stream) { struct start_req req; @@ -3663,7 +3676,13 @@ int avdtp_start(struct avdtp *session, struct avdtp_stream *stream) * to start the streaming via GAVDP_START. */ if (stream->open_acp) { - stream->starting = TRUE; + /* If timer already active wait it */ + if (stream->idle_timer) + return 0; + + stream->idle_timer = g_timeout_add_seconds(WAIT_TIMEOUT, + wait_timeout, + stream); return 0; } -- 1.7.10.2 -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
