Have searched for this and cannot find any info on this particular error. Maybe I am not doing something right.
My sketch works great, however, when this command is inserted, the serial monitor and blynk IoT stops working. I see the seconds in Blynk count up for a couple seconds, then everything stops.
if ( Percent / 1000 <= 25 && millis() > 60000 ) {
Blynk.logEvent("low_water","Please add water to Piney!")
Serial.println("add water to tree");
}
The if condition is not even met, yet it stops the entire thing.
But if I just comment out that one line as so…
if ( Percent / 1000 <= 25 && millis() > 60000 ) {
// Blynk.logEvent("low_water","Please add water to Piney!");
Serial.println("add water to tree");
}
then the rest of the program and I see the rest of the data on Blynk.
I do have the event setup in Blynk.
EDIT: any instance of Blynk.logEvent(“eventname”) causes entire program to not run on Blynk. I have tried it many ways.
FYI… full code here: (please excuse sloppy code, I am beginner 
)
/*************************************************************
WARNING!
It's very tricky to get it working. Please read this article:
http://help.blynk.cc/hardware-and-libraries/arduino/esp8266-with-at-firmware
You’ll need:
- Blynk IoT app (download from App Store or Google Play)
- Arduino Uno board
- Decide how to connect to Blynk
(USB, Ethernet, Wi-Fi, Bluetooth, ...)
There is a bunch of great example sketches included to show you how to get
started. Think of them as LEGO bricks and combine them as you wish.
For example, take the Ethernet Shield sketch and combine it with the
Servo example, or choose a USB sketch and add a code from SendData
example.
