Hi, this is a follow-up to "How to check send state?" but I start a new discussion since it is a new question:
I'm trying to enqueue some data into lwIP's send queue that are generated from within my applications main-loop (which is not allowed). Now my solution is to just set a flag and then fetch and enqueue the data out of lwIPs thread context. This is done once periodically within my poll-function (specified by tcp_poll()) and once immediately from within my recv-function (specified with tcp_recv()). My question: are both running in same IRQ-context or are they triggered by different ones so that filling the send buffer this way would lead to troubles too? A check if previously enqueued data are fully send of course is implemented. Thanks for all your kind help :-)
