  Step 1

  First, we need to upload the bin file to module

  download https://github.com/will127534/7681-ATcmd

  also SDK from Mediatek Labs

  and connect Linkit connect module with any kind of UART to USB

  with

  RX <= TX

  TX => RX

  VCC <= 3.3V

  GND <=> GND

  then copy MT7681_ap_header.bin MT7681_sta_header.bin under /bin

  to /Uploader in SDK.

  Open a command line to /Uploader

  enter mt7681_uploader.exe -f MT7681_sta_header.bin -c COMX

  with COMX need to change to your com port.

  you will see this after uploaded complete.

  Step 2

  Second, connect module and Arduino with :

  Module <=> Arduino

  RX <= TX

  TX => RX

  VCC <= 3.3V

  GND <=> GND

  RST <= Any output pin

  Step 3

  Last, copy all the files under Arduino Sample to your Arduino Library folder

  then open Arduino IDE, select files>Samples>MT7681>connect_demo

  Change ssid and key to the AP you want to connect

  and RST to the Output connected to Linkit connect module.

  also change constructor 7681Wifi wifi(&Serial1);

  if using UNO = > change to Serial

  and press Upload, then it is finished.
