DIY enable BMW ENET cable with WiFi Connection

I have too much time on my hands and like to solve problems. Got tired of always plugging in the BMW ENET Ethernet to OBD F-series coding cable for coding and diagnostics so I decided to explore a wireless alternative. The idea is to leave a module plugged into the OBD2 port and switch the ignition and the module on, then code/diagnose from the comfort of my sofa.

What I basically did is hack a TP-Link TL-WR802N, an 38-pin OBD2 connector (see picture below), buck converter and miscellaneous parts to build the final product. I tried the concept before I integrated all the parts and armed with Wireshark, I devised a configuration for the wireless router to work with the car.


I may still need to tweak few things for the box but overall it works really well, and I don't have to sit anymore in my garage to code or diagnose! It was too much miniature soldering in tight areas, if a product like this exists I'd gladly buy it and not build it!
