Trying to send mail from the core. The code below worked fine on an Arduino and a wifi shield, there aren’t any delays in it, not really sure what is going wrong here. It all seems really straightforward, the problem is that I call this function and the core just completely stops responding to any f…

Not sure about how what you have will work. Let’s see the rest of your code :smile:

Not a problem, here you go. long lastUp = 0; int SenseDelay = 20000; byte smtp[] = { 46, 105, 158, 236 }; //mailjet SMTP server //int SensorValue = A0; int SensorValue = 200; //filler value so I dont have to wait on a sensor TCPClient client; void setup() { pinMode(SensorValue, INPUT); } …

[image] jboswell: if (millis() - lastUp > SenseDelay) { Aha, here's your problem... 20 second hard delay :wink: Please see my post here on the same topic with the same problem: [image] TCPclient connect with authentication to SMTP server Trou…

That’s not a delay though, that’s just a simple math operation that executes code inside every time millis - lastUp is greater than 20000 milliseconds. Main continues to loop until that returns true, then it dives into the second block of code (the else if). That is of course all dependent upon my u…

Hi @jboswell In general, you are not checking any of the responses from the mail server, maybe that’s an area to explore? Have your tried doing the sendmail steps by hand by telneting to port 587 on your mailhost? Maybe something has changed there, like requiring STARTTLS. I would definitely chan…

Wow, sorry… I’m trying to do too much today and not focusing very well! Yeah you’re fine on delays. My bad.

Hey @bko , It’s like you are reading my mind, I was just telnetting in and checking everything. I found something weird already, when I put in the first command after connecting it fails and then I type it in again and it succeeds. It looks like almost anything I type in first fails, I have to go ch…

No worries, we all have those days. Thanks for looking at it!

My routine works fine is I dont use the AUTH LOGIN part… If I’m on my ISP smtp server, that doesnt require authentication, works A1, if I changed ISP and try to reach my original ISP, it requires SMTP login and there is a failure… where my arduino does it no problem with same code…

The one thing the arduino can do that the spark core currently can’t do, is sit around forever waiting for a routine to finish. It’s possible that the arduino just hangs out a long time, and that same response is hanging up the core. On the arduino, can you put little time stamps in serial prints…

Okay, dove into this a bit, mostly I modified the code to also output everything to serial, and I added some very basic logic to wait for a particular status code back from the server before proceeding. It sent me a few (not properly formatted emails), but it sent an email!
