1. Overview
1. Overview
This guide is intended to help users run ping test on the ESP8266 easily and quickly. It
demonstrates the testing of network connectivity by running ping test in Station mode or
SoftAP mode of ESP8266.
The ping test has been demonstrated and run on the ESP-Launcher. However, with
appropriate build settings, the test can be made to run on any ESP8266-based system.!

4. Test Procedure
4.1. Download Firmware
1. Download firmware into the ESP-Launcher. Use Flash Download Tool (ESP8266
DOWNLOAD TOOL) to download ./Bin-FW/demo.bin into address 0x0000. For more
details about using Flash Download Tool, please refer to Appendix Ⅱ.

4. Test Procedure
2. Run the firmware to confirm that the download is successful.
•Connect the ESP-Launcher to the PC using the Micro USB cable.
•Open the UART tool on your PC, and configure the baud rate as 115200.
•Toggle the switch “2” on the ESP-Launcher to the upper side to set it to be the
program execution mode.
•Next, toggle the switch “1” to the upper side to power up the ESP-Launcher.
•If the UART outputs the logs below, it means that the firmware is successfully
downloaded.

Figure 4-2. UART Output Logs
4.2. Set ESP8266 to AP Mode for Ping Test
1. Set UART baud rate to be 115200 for firmware installation. The illegible characters are
printed at the baud rate of 74880 and this is normal during correct power-up. Reset
ESP8266 upon power-on, when the “ready” message is printed, it means that the
firmware is running properly.

⚠Notice:
The baud rate of using AT commands is 115200.

4. Test Procedure
2. After the “ready” message is displayed, users can send the AT command below to set
the SSID and password of ESP8266 SoftAP.
•AT command: AT+CWSAP=“Smart1ap”,“espressif0-1”,5,3
•Result:
#
Figure 4-4. Setting ESP8266 to AP Mode
3. Connect the PC to ESP8266 SoftAP of which SSID (Smart1ap) and password
(espressif0-1) are set in the Step 2 above.
4. Click the network icon #(in the task bar at the lower right corner of the PC desktop
screen). Connect the PC to the ESP8266 SoftAP (SSID: Smart1ap, password:
espressif0-1).

Figure 4-5. PC Connecting to ESP8266 SoftAP
⚠Notice:
•AT commands always terminate with “\r\n”. ESP8266 will not recognize commands not terminating
properly and will return “ERROR”.
•For more information on AT commands, please refer to ESP8266 AT Instruction Set.
⚠Notice:
It is recommended to have a PC with an external wireless card to connect to ESP8266 SoftAP as a station.
Using internal wireless card may cause poor Wi-Fi connectivity.
