Is there any possibility to limit socket buffer size (2nd > write to socket will block, when I will try to write 2nd packet, before > 1st is not sent) ? l2cap actually doesn't send the packets, it calls the hci layer to queue the packets for sending. The hci layer eventually will send the packet. You can try to use the L2CAP Enhanced Retransmission Mode with txWindow = 1. So, you will need to wait the ack from the remote side to send the next packet. > > > best regards, > sorry for my English > -- > 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 > -- Gustavo F.
