Workshop : Internet Of Things Using ESP8266-Details


The board you got should already have AT with all the needed libraries flashed on it. In order to access its
console, you will need to connect it to your computer with the micro-USB cable, and access the serial interface that
appears with a terminal program
For windows the serial interface to appear in your system, you will need to install the drivers for CP2102. Once you have that,
you can use either Hyper Terminal, PuTTy, ESPlorer or CoolTerm to connect to it, following this guide.
The parameters for the connection are: 115200 baud rate, 8 data bits, no parity, 1 stop bit, no flow control.
Hello world!
Once you are connected, press “enter” and you should see the ESPlorer terminal prompt, that looks like this:

It’s traditional to start with a “Hello world!” program, so type this and press “enter”:
If you see “Hello world!” displayed in the next line, then congratulations, you got it working.
