I am using esp32 huzza32 board . i want to deepsleep my device for several time . but i am unable to sleep my device it restart but never sleep.

My code:

E.on('init',function() {
digitalWrite(new Pin(13), 0);
var count = 0 ;
setInterval(function() {
count++;
console.log(count);
if(count >= 10 ){
ESP32.deepSleep(100000);
}
}, 100);
});

Output :

The timeout is in microseconds (don't ask why!), so 100000 is 0.1 seconds. So it's probably working just fine.

ESP8266/ESP32 deep sleep does work by completely rebooting the device. If you want something that doesn't then buy an official Espruino board which can sleep without losing the contents of memory.

You need to go to settings communication and on the end of the list is Save and Send and select Direct to flash (execute code at boot)
