Wi-Fi Repeater - ESP8266

Hardware

ESP8266 (CH340)

Tutorial

• Install driver CH341SER_win.zip
• Connect NodeMcu and check com port -> Control Panel >> Device Manager >> Ports
• Open flash_download_tools_v3.6.8.exe -> for me was ESP8266
• Put the same settings as in picture (BAUD, FLASH-SIZE, etc):

• Open Arduino IDE -> Tools >> Serial Monitor and select Both NL&CR and 115200 as picture below:

• Press 'RST' switch on NodeMcu and in serial monitor:

1. set ssid 'xxxx' (in windows to show SSID in terminal netsh wlan show profiles)
2. set password 'xxxx'
3. set ap_ssid 'xxxx'
4. set ap_password 'xxxx' (min 8 characters)
5. set ap_open 0
6. save
7. quit

Please note:

• Replace 'xxxx' with your own credential and without quotes
• During settings add '%20' if ssid contains spaces i.e. 'My Repeater' will be 'My%20Repeater'
• In case of issue → erase & upload stock firmware (bin folder, guide in References/Codes) ^*
