Reverse Engineering the apk

[Kris Gainsforth]

Before I go in and start to unpack the apk and poke around, I just wanted to make sure I haven't duplicated efforts. Does anyone here know of or has started to reverse engineer the app?

I have not seen anything, but please post your results.  I have had sniffing out the bluetooth protocol on my list but have not gotten to it yet.

I'm going to unpack the last apk this week and take a look around. I'm not much of an Android dev, but hopefully I can figure out a few things.

The radio uses BLE technology to read and write from various status and control registers, in order to get data to/from the phone.

The radio also uses a “reverse headset” Bluetooth device profile that uses the phone as a Bluetooth headset (only supported on Android) to get audio to/from the device for attaching to network channels, SSTV decoding, etc.

The problem with reverse engineering the app is that the manufacturer is still actively developing the platform. That means as newer versions of the app are released and newer firmware releases are made, the registers and control protocols change.

A few have looked into it but the platform is a moving target right now.

That's what I'm seeing as well. The latest updates are messing with GUI stuff too. I'm gonna hold off but I am going to figure out import and export of channels.

I'm mainly interested in this device for its built in APRS capability. I'd love to be able to send and receive information over the air directly from a terminal window. Before I duplicate effort myself, has anyone sat down with a Bluetooth sniffer and Wireshark and tried to document the commands between the app/handset and the device? If so, is that documented anywhere? What about a firmware dump?
