Yes you are correct, the event handlers will not do anything in setup. Main runs 'setup', then loops infinity through 'loop', but gives the serial event handlers a chance to run in between. The actual main that runs on the arduino is this. Jan 01, 2015 Following on from the FTDI + ESP8266 post, if you do not have a FTDI serial adaptor you can use an Arduino. Here is how to set up the Arduino to talk to the ESP8266. I an using a 5V Arduino Nano which of course is 5V. The Esp8266 is a 3.3v device and so I am using a voltage divider to bring the Arduinos 5V down to 3.3v.
A small nothing left aside. SerialEvent #752. Fredericplante opened this issue Sep 6. Hi, is SerialEvent Available now? Im trying to send information via serial from arduino to esp and back the other way, ESP is acting as a web server so if use serial.read is going to block all the others function. Part that will call the Serial.

I'm working on an Arduino project and would like to receive some commands from the
Serial port with the arduino Serial event. However it always won't fulfill a condition, making the code not knowing the serial event has been finished. Here is my code.
I've tried passing the string dsolimano
`Hello| from the serial monitor yet it won't respond. Additionally, I've tried the Line ending with No Line Ending and Newline yet it won't work, Can anyone please help? Thanks!

I have figured the problem,
Serial.read() will only read a byte per time, for example, `Hello| will be split into
Intel starter pack download. So for the first time, the
if (inChar ' `') is true, therefore entering the actions inside, however from the second char, (H, e, l, l, o, |) are not the char '`', meaning if (inChar ' `') is not true, not letting it to enter the condition after that.
Here should be the propoer way of doing it:

Is
inputstring being defined in the sketch? Also, loop() and setup() Deviantart hetalia model download mmd. have some tasks to complete. See: http://arduino.cc/en/Tutorial/SerialEvent this page has a good starting example, get it to work first and then modify it for your specific code.
Arduino Serial Port Event
When you type 'Hello|' and press enter, what is the '|' for? Is there a reason why you are NOT testing for 'n' as the line termination character?
Also, you are testing for inChar '`' and then adding it to string, but you are typing in 'Hello'? Serial I/O passes one character at a time, so you need to allow the inChars that are typed in.
