Most of the guidance floating around the internet for extracting the Bluetooth HCI logs from Android is grossly out of date. Here is how I managed to achieve it with a Samsung Galaxy S10 running Android version 10.
Things that don’t work on this version of android, for this phone at least, include:
- Live capture via Wireshark’s
androiddumptool (https://stackoverflow.com/questions/53751028/live-capture-of-android-bluetooth-traffic-via-wireshark) - Copying the file directly from the filesystem using
adb pull
Here is what worked for me:
Press “Build number” 10 times
Step 1: Enable developer mode
Go to Settings, About phone, Software Information and tap the “Build Number” row 7 times. The phone will show a notification counting down once you’ve tapped it a few times, and will confirm that developer options have been enabled.
