I am thinking of using an ESP8266 or similar to have wireless access to the UART of the Omnia. Right now the UART is completely inside the chassis and so difficult to access. Also, since it’s UART I’d fry it if I used a standard 9-pin serial port to connect to it (after, say, putting my Dremel to some use and mounting such a connector to the chassis).
My idea is to mount the microcontroller inside the Omnia chassis somehow and have the Omnia power it (it’s no big deal if the WiFi only reaches a few meters outside the chassis). There are basically two bits of functionality I’d like to have:
- be able to access the UART by somehow forwarding traffic both ways
- be able to (hard) reboot the Omnia
This functionality should be accessible via WiFi/WLAN and preferably I’d have it go through SSH.
Is anyone aware of such a solution, even if for some other similar device and not the Omnia itself?
Is there perhaps anything better available to get similar functionality?
