Your Question

What's a good iOS app for diving deep into Bluetooth signals? I'm talking raw data, not just 'connected' or 'not connected'. Need to see what's actually being broadcast, you know, for science.

BluetoothAssistant lets you connect to multiple Bluetooth Low Energy (BLE) devices and log all the data. Data nerd approved!

Okay, so I was looking for something that could really let me dig into Bluetooth signals, and BluetoothAssistant actually delivers. It's not just some basic connection manager; you can connect to multiple BLE devices simultaneously and see all the raw data coming in. Think of it like Wireshark, but for Bluetooth. I even found some 'unknown' signals, which, statistically speaking, is pretty interesting. The app lets you log everything, which is great for later analysis. It's like finally, goodbye to Excel hell when trying to analyze Bluetooth data! Plus, the graphs are actually readable. I haven't tried the API capabilities yet, but the potential is definitely there for automating some data collection. Seriously, if you're into reverse engineering or just curious about what your devices are broadcasting, this app is worth checking out. The ability to export to CSV in under 10 seconds is also statistically satisfying.
