Hello David, no it's not the listener pcb. I checked the pointers, and the pcb I used in tcp_write and tcp_output is the one that I get as an input parameter to tcp_accept callback function. The small argument the I use the right pcb is that the data comes to the other side ... unfortunately a bit lather than intended and that's the reason for my tcp_output digging. My hunch is that this if is true for the pcb that is currently being processed by lwip for input data cumming from the other side ... but that is only a theory
