No more wires!

Jumped on the preorder for the MHD wifi dongles. These look like a pretty simple device based on a PIC18 microcontroller and ESP8266 chip for the wifi. Seems strange that they did not simply use th ESP8266 for the processor.

The ESP8266 is just running a Jeelabs esp-link interface, which is basically a wifi->serial converter. This has a wifi access point and a web interface in which you can configure it.

By default, there is NO wifi security at all. This means anyone can connect to your car while it's plugged in. The SSID of the wifi is not unique (so if a bunch of cars were nearby it'd be hard to know which to pair to)

The first thing I did was to determine how to get a password on the MHD dongle, as you could easily log into anyone's wifi dongle and do some nasty stuff. Could easily lock everyone out of the unit by changing settings or adding a password, or upload a dodgy flash and brick the car

Just log into https://192.168.4.1 and change the SSID and password to your own!
