Problem sending mail via LPC1769, RL-TCPnet Keil IDE

[zaidshaikh]

Hello,

I am working on LPC1769, Keil IDE and using RL Tcpnet. I am unable to send emails via SMTP. I am either getting  a SMTP timeout or SMTP error. i tried using port 25  and port 80 but it didnt work.

Please suggest.

Hi Zaid Shaikh,

Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
I'd highly recommend you to visualize the Ethernet communication via the Wireshark and share it, as it will help us to locate the root cause.
Have a great day,
TIC
