When I tried to run the ble_scan I got an error message I don't understand. It wasn't fixed by running it with sudo privileges.

I encountered the same problem, did you solve it later？

@Huangkaiping Sorry to say that I'd forgotten entirely about this, and no, I never came across a solution.

I've updated my dev machine

wim@WimPi4-Dev:~/gattlib/build $ uname -a
Linux WimPi4-Dev 6.1.21-v8+ #1642 SMP PREEMPT Mon Apr  3 17:24:16 BST 2023 aarch64 GNU/Linux

but doing a git pull in the gattlib directory told me I was up to date. I reran cmake and make and the non-sudo ble_scan command no longer produced the same error, I got my BLE development done last year and am not currently thinking about these tools.
