Hallo guys.
I have some troubles, when i am useing this code.
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 and their port 2525.
Kind regards Emil
I would start with changing your #defined 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”. And it works now.
Thank you!
