BastWAN_Timed_Wakeup

An example demonstrating the usage of the ArduinoLowPower library on BastWAN. It is using the ElectronicCats port of the ArduinoLowPower library, and is based on the TimedWakeup example.

When using this example, you need to set the clock source as 32KHZ_CRYSTAL, as shown below:

Setup

The main line of code here is:

  LowPower.attachInterruptWakeup(RTC_ALARM_WAKEUP, dummy, CHANGE);

Where dummy is a function that will be called on wakeup. Here we'll just increment a counter, for the LoRa packet that will be sent.

void dummy() {
  // This function will be called once on device wakeup
  // You can do some small operations here (like changing variables that will be used in the loop)
  // Remember to avoid calling delay() and long running functions since this function executes in the interrupt context
  count++;
}

The in loop() we will send a small packet with the count updated, and go back to sleep with LowPower.sleep(30000);. That's it!

The BastMobile only displays a few characters of the incoming message.

But you have the full message here in the individual message view.
