I have been trying to get the Simplemail e-mail demo program to work on the EXP430FR5739 board and I have hit a major roadblock. I have successfully gotten the unit to do First Time Config and have a reliable socket link.
The unit sets up a socket correctly and gets the correct response from smtp2go.com, i.e. "220..." etc. When I send the "HELO me" command smtp2go responds with the "HELLO me...." acknowledgement. When I send the "FROM: me@me.com" command the response buffer occasionally gets the "250" response, but no more than 5% of the attempts. When I try to send the "RCPT TO:they@they.com" I have gotten maybe 1% of my attempts to get as far as the "250" acknowledgement. I have never gotten the code to successfully get the "354" intermediate command after sending "DATA". In all cases when the code crashes the response buffer is always blank.
Any ideas on how to get this example code running?
