Quick Start – NanoESP & Pretzelboard
When you attach the board for the first time via the MicroUSB connector, your PC will try to install a driver. If this does not work automatically download and install the driver here.
The ArduinoTM IDE provides the simplest way of programming the development board. Download the IDE from www.Arduino.cc. When you start the software, you first have to choose the correct port and board. For the latter, you select the Arduino NanoTM (ATmega328 processor).
In order to test the WiFi module, you open the serial monitor and select a transfer rate of 19,200 baud. As long as no other program is loaded into the controller, the monitor should display a few messages. Furthermore, you will now find an open WLAN called NanoESP. To control the module yourself, use the Software Serial library via pins 11 and 12 with a transfer rate of 19,200 baud or just donwload the programm to your computer and upload it via the Arduino Software to your board:

The serial monitor has to be set to CR and NL. The following AT commands are useful for the first test:
Test command: AT
