# How to add WIFI (With ESP-01)

1. Donwload flashing tools for ESP8266

    https://espressif.com/en/support/download/other-tools?keys=&field_type_tid%5B%5D=14

2. Download ESP-Link firmware 

    https://github.com/jeelabs/esp-link/releases

3. Flash the ESP (GPI0 <--> GND on connecting)

    |blank.bin | 0xFE000|

    |esp_init_data_default.bin | 0XFC000|

    |boot_v1.6.bin | 0X0 |

    |user1.bin | 0X1000 |

    |Setting | Value|

    |SPI SPEED | 26.7MHz|

    |SPI MODE | DOUT|

    |DoNotChgBin | Unchecked |

    |BAUD | 115200 |

    Actions:

    1) Erase

    2) START

6) Open http://192.168.4.1 in the web browser

7) Configure WIFI SSID & Password

8) Disable Debug logging to UART

9) Wire ESP to DLC32 as showed on the diagram 

    Use AMS1117 (LM1117) as a 5V -> 3.3V step down regulator

10) In LaserGRBL connect using Telnet (port 23)

> Remarks

 - I tried to used ESP-12 which can be power with 5V without any extra component. However, it's susceptible to hight level on `GPIO15` (UART switch mode)  during the boot so it's not working with Sculpfun S10 (you need to disconnect RX from the machine, power on and then connect RX back)
