Sorry, but there is no led notification in new moto e. it has active display. when you up the device the screen will lit up it self and show if you have any notification or not. Now I am quite frustrated for this reason.:crying::crying::crying::crying::crying:

That's the battery LED, used only when the battery goes low. As far as I know, the Moto E 2nd gen unfortunately doesn't have a software-accessible notification LED.

With a custom rom you can access it, im using cm12.1 and i have text notifications blink it

I made a custom binary for the leds so in CM12.1 and AOSP when you plug the USB you have the notifcations..
For so unknown reasons, when you unplug it, the "led driver" is told that there are no more notifications to show.
I'll be investigating on this when I have more time. If I find who and why I am told to stop notifications in the project, I'll be able to make it work with cable unplugged to.

For missed calls and sms will be modding?

Hey, let me know if there's anything I can do to help, I've been looking at the led code and comparing to see where the difference is. I don't have a ton of time to mess with it, but look at drivers/leds/leds-qpnp.c around line 3115, comparing to nexus4 sources
MOTO E:
Code:
led->default_on = false;
rc = of_property_read_string(node, "qcom,default-state",
&temp_string);
if (!rc) {
if (strncmp(temp_string, "on", sizeof("on")) == 0)
led->default_on = true;
} else if (rc != -EINVAL)
return rc;
NEXUS 4:
Code:
led->default_on = true;
rc = of_property_read_string(node, "qcom,default-state",
&temp_string);
if (!rc) {
if (!strncmp(temp_string, "off", sizeof("off")))
led->default_on = false;
} else if (rc != -EINVAL)
return rc;
Like I said, I haven't had time to test, the logic is clearly inverted in the moto e driver but there's got to be something tied to the charger state too.

I might be wrong but led driver is working fine. If you go by hand and set manually the values in the /sys/classes ... you'll get a blinking led. There real issue is why does the NotificationManager doesn't ask for a blinking led, unless the power cable is plugged in.
If you use my binary you'll see that I added some logs for the lights requested. And NotificationManager explicitly ask to stop blinking when unplugging the USB cable.

its posible to use cyanogen kernel with stock rom so we can use notification led??? because en cyanogen and pacman the led its full working but i prefer stock rom
