This is awesome!
I am using an escort max 360 I have connected to an old Bluetooth module. I am sniffing the data going between the two and I plan to use the Arduino in place of the Bluetooth module once I figure out which commands keep the detector satisfied and allow the communications to continue without the Bluetooth module
&
It most likely is just binary data but I have been reading it as hex packets. I used an oscilloscope to find that the data coming from the detector is an inverted ttl signal at 57.6k baud. The signals going to the detector from the bluetooth module are a standard (non inverted) ttl signal (both at 5V). I found it odd that they would invert one signal and not the other but im sure they had a reason.
Once I found out which packet created the alert and what each byte does, I paired the bluetooth module to the app and injected different hex values into the bluetooth module until I came up with all of the scenarios that I could find. Same deal with controlling it. I went through the app and sniffed each signal for the different commands
