[En-Nut-Discussion] PPP GPRS Connection - URL Request Problem

[Harald Kipp]

Hello Tim,

mmmh...no idea either. At least

- RS232 is fully OK
- PPP connection seems to be OK up to IPCP handshake

Error 10057 means, that the application tried to use
a TCP socket, which doesn't have an established
connection.

May be a timing/sync problem between PPP and TCP.
You can try to add a NutSleep() before NutTcpConnect().
