Overview

Caveats

If Steam Deck performs a system update, some or all changes may be lost and have to be redone (to be tested). To overcome this, rwfus can be used: https://github.com/ValShaped/rwfus (not tested)

Supported and/or tested devices

Steam Deck LCD with rtl8822ce (tested working, show rssi in wfb-cli gs) Ugreen rtl8812bu (tested, working. Does not show rssi in wfb-cli gs) ssc338q+imx415 (NOR16MB) GK7205V300+IMX335 to be tested

Installing OpenIPC software on camera module

TODO

Include the option to use external USB rtl8812au network card Connect directional antenna (Eachine Stingpad) to steamdeck network card (will not do this, but theoretically possible) Create script to facilitate wfb_ng installation Someone need to test on OLED Steam Deck
