Hallo guys.

I have some troubles, when i am useing this code.

> <https://gist.github.com/anonymous/404e907f367dc64a2727d605a8b6e5e5>

my proton starts flashing SOS and followed by either 11 or 12 flashes, Do any of you know what I am doing wrong?

I am trying to use [smtp2go.com](http://smtp2go.com) and their port 2525.

Kind regards Emil

I would start with changing your `#define`d strings to `const char[]` variables, transition to the current version of `Spark.variable("emailSent", &sentOnce, INT);` to `Particle.variable("emailSent", sentOnce);`, change `SPARK_WLAN_Loop();` to `Particle.process();` and use less `String` objects and rather go with C strings (`char[]`, `char*`).

I guess especially the “overuse” of `String` causes heap fragmentation which eventually leads to your SOS panic.

Does their service allow you to use it without SSL/TLS? Most do not.

Thank for the help.  
I changed my setup to use “[IFTTT.COM](http://IFTTT.COM)”. And it works now.

Thank you! 😄
