Re: [lwip-users] tcp_write() problem from outside callbacks functions

[Yann Suisini]

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 :(
