Question about setDeepSleep

Hi,

I have a problem with the setDeepSleep. My understanding is that it should work on the Espruino Pico. Is this correct?

It does lead to weird effects for me. Basically I am using the following snippet from the power tutorial (with different constants):

setInterval(function() {
    digitalWrite(LED1, 1);
    setTimeout(function () {
        digitalWrite(LED1, 0);
    }, 5000);
}, 10000);
setDeepSleep(1);

The code works fine when connected to USB (my understanding is that deep sleep is disabled in that case anyway). It does not work when connected to a battery. Instead of blinking for 5 seconds every 10 seconds, it blinks every 10 seconds for like 3 ms (measured by monitoring the current consumption with an oscilloscope).

If I remove the setDeepSleep, then it works fine even with a battery - albeit with a lot higher power consumption, of course. I monitor the battery voltage and stays constant at about 4 V (Li-Ion).

Am I doing something wrong?

Thanks!
