First Steps¶

Getting started¶

By default the module is in AP mode.
Connect to the Linkit_Smart_xxx network and go to mylinkit.local URL
Set password and login to the web configurator
Select “Network” tab, switch to “Station mode” and connect the device to the local Wi-Fi network

Boot up the board and wait for the WiFi LED to go off.
Press and hold the WiFi button for at least 20 seconds then release.
The WiFi LED will blink fast for 1 second, and then reboot to perform a factory reset.

Download the latest .. _LinkIt Smart 7688 Firmware: https://docs.labs.mediatek.com/resource/linkit-smart-7688/en/downloads
Unzip and copy the image lks7688.img file to the root directory of a FAT32 USB drive.
Attach the USB drive to the HOST port of the board with an OTG cable.
Press and hold the on-board WiFi button.
Press the MPU reset button once while holding the WiFi button.

The device will automatically reboot after firmware update is complete.

# opkg update
