Ticker works fine using the example sketches and the MQTT client works perfectly fine as well. As a very basic example I'm publishing a simple message every 10 seconds to the MQTT broker. Doing so with a loop function like this works perfectly fine:
CODE: SELECT ALL

Code: Select all

loop() {
  send();
  delay(10000);
}

but as soon as I try to replace that with a Ticker the module reboots after a few seconds:
CODE: SELECT ALL

Code: Select all

Ticker sendTicker;

setup() {
  ...
  sendTicker.attach(10.0, send);
}

loop() {
}

and the reason shown for the reboot is wdt_reset. Neither the Ticker nor the MQTT client libraries have an issue with the watchdog separately.

The Ticker approach appears more elegant as the loop could still be used for different purposes...
