Send Text Message Using SMTP API

This example will allow you to use an SMTP server to send a SMS message to a cell phone.


With the SMTP API you can send an email to your phone as a text message.  There are a lot of different servers you can use the default in this example is using GMAIL through the smtp.gmail.com server.  Most SMTP servers should work, but the server and cell phone needs to be compatible to send and receive SMS messages, more information can be found in the reference.

I know that I am typing in my password email combo correctly however I continue to get the error saying I have typed in the wrong username password combo. What am I doing wrong? I am running LabView 2015

I ran into this same issue.  You likely need to change a security setting in your email.  When I tried this on Gmail (with the correct authentication, but getting the same error message) I logged into my email and Gmail had sent a message saying they were blocking access from an unauthorized program.  In the email, there was a link to allow this type of access (they warn that it's lower security, but I did it anyways).  Once this was enabled, it worked like a charm.

Not my tempo... AGAIN!

The "from" needs to have the full e-mail address, not just the "username", so concatenate the username with @gmail.com

This fixed it for me as I was having the same problem.
