1) MKS-HLKWIFI intruduction:

MKS-HLKWIFI is based on HLK-RM04 module. It can work with MKS Gen , MKS Mini board or MKS TFT28 V1.1  LCD  and control 3D printing remotely through wifi.  In this tutorial, we only give instruction on how to use MKS-HLKWIFI  working with MKS TFT28 V1.1.

2)Parts and Devices in this project

4)mks_config.txt Wifi Configure(Only MKS TFT28 V1.1 or higher version supports MKS-HLKWIFI module)

if you purchased MKS TFT28 or MKS TFT3.2 touch Screen,You will have a config file mks_config.txt in the driver. In this file, you will see many configuration information for MKS-HLKWIFI module(see following points):

i)Wifi module selection in section cfg_wifi_mode: set 1 for AP mode and 0 for client mode

Client mode :

If you set cfg_wifi_mode value to 0 (client mode), the MKS-HLKWIFI module works as a client of a wifi hotspot. You should configure following information in order to get it connected to hotspot.

A.Wifi hotspot name setting

in “cfg_wifi_ap_name ” section, write the wifi hotspot name.

B.wifi password setting:

In “cfg_wifi_key_code ” section, write wifi password of the hotspot you need to connect to.

C.DHCP flag:

in “cfg_ip_dhcp_flag” section, set 0 to config static IP, set 1 to configure DHCP IP.

D.Ip address assignment

If you set “cfg_ip_dhcp_flag” to 0 (static IP), you need set the static IP address in  “cfg_ip_address” section.

E.ip mask

set IP mask in “cfg_ip_mask” section

F.ip gateway

set gateway in “cfg_ip_gate” section

AP mode:

If you set cfg_wifi_mode value to 1 (AP mode),  MKS-HLKWIFI module works as a wifi hotspots, you should config following value in order to allow other device to connect it through wifi

A.wifi  hotspot Name

in “cfg_wifi_ap_name” field, set the wifi name of your hotspot.

B.wifi password

in “cfg_wifi_key_code” field, set the hotspot password

5)Connect MKS-HLKWIFI module to Wifi network

In section 4), we have talked about 2 working mode for MKS-HLKWIFI module works : client mode and AP mode.

If you set MKS-HLKWIFI module works  in client mode, you can do following steps to connect it to Wifi hotspot:

I)save above mks_config.txt in a SD card (or USB storage) and insert it into MKS TFT2.8 LCD. Turn on the power, MKS-HLKWIFI  will connect wifi hotspot as per your wifi hotspot/password setting. If it connects to wifi hotspot successfully, LCD screen will show “Connected”, otherwise LCD will show “Disconnected”
