WakeOn RI in SLEEP_NETWORK_STANDBY?

General

Well that’s cool - it works!

Here’s the code I used on the Electron:

#include "Particle.h"

SerialLogHandler logHandler(LOG_LEVEL_TRACE);

const int SLEEP_PIN = D2;

void setup() {
	Serial.begin();
	pinMode(SLEEP_PIN, INPUT_PULLUP);

}

void loop() {
	if (digitalRead(SLEEP_PIN) == LOW) {
		Log.info("turning on AT+URING=1");

		// Enable wake on all URCs
		Cellular.command("AT+URING=1\r\n");

		delay(1000);

		System.sleep(RI_UC, RISING, 120, SLEEP_NETWORK_STANDBY);

		// This delay is to allow the serial monitor to reconnect only
		delay(2000);

		Log.info("woke from sleep mode");

		// Turn URING back to the default value (only notify on SMS or voice call)
		Cellular.command("AT+URING=0\r\n");
	}
}

I entered sleep by pulling D2 to GND. A few seconds later, the Electron went to sleep.

Then I used the ping feature in the console to ping the Electron, and it woke up and even returned success for the ping.

Log output:
