Hi @dkgoodman ,
dispite not really understanding how stack and heap are handeled, my example App which uses https basically still works but has occasional hangs.
-Wio Terminal App Sending Sensor Data to Azure Storage Tables - Hackster.io
Occasinal hangs were repeatedly reported for WiFi use with Wio-Terminal.
-rpcWifi problem when wifi is lost
As already said I had to move buffers outside the normally used memory areas to get https working.
Additionally I avoided to use Strings and used char arrays instead, avoided to use debug messages and were needed used them like Serial.println(F(“Text”));
Occasionally ntp doesn’t give a response and it was needed to handle these situations gracefully.
