Which GPIO do I need to use to reset wifi? (case: LinkIt device difficult to access, can't easily reach the onboard wifi button.)

Hi, According to the developer's guide, there is no gpio to reset wifi directly. http://labs.mediatek.com/fileMedia/download/87c801b5-d1e6-4227-9a29-b5421f2955ac (From: jerryyip)

How can a 2nd ethernet port be enabled? The MT7688A has a 5-port ethernet switch, so it would be nice to easily enable at least 1 more ethernet port by adding magnetics. Is this possible?

The datasheet is for MT7688, and not for Linkit7688. The subtle difference here is the way this board is manufactured several IO ports had to be made unavailable. If you can prepare your own board using MT7688, you will have full access to all of these peripherals and a PCIe port too..

Hi, How can I change the default IP. If connected to LAN and this IP is used yet from another device - I can not access the linkit.local host?
on Apr 06,2017
Reply upvote ()
it is "mylinkit.local" If you are still now able to ssh into it.. use network mapping tools to look for the ip address "who is on my wifi for windows" or nmap for a linux console. I have tried the static IP thing, beleive me.. in the long run, you wud not wan that, just stick with a host name.
