It seems that only possible ERR_CONN cause is you call tcp_write with a
connection in a invalid state. Can you tell us what is the "tcpweb->state"
value when you call tcp_write ?

In fact I didn't put the connection part in the previous mail but the
connection is ok :) (the tcp_new/tcp_bind:tcp_listen/tcp_accept sequence). Once
the connection is established the tcp_write data frome the callbacks are sent
well . But the tcp_write from the main loop that you can see in the source
always return the ERR_CON . I read 2 or 3 times the rawapi.txt . But I
probably missed something :(
