Startup fails with: error: EINVAL: Invalid argument

[sooda]

FYI, ruuvitag-listener (latest master as of writing) does not work on systems with a new enough Linux kernel; at least 6.8.7 is affected. adapter.connect() in on_measurement() fails, as the kernel refuses btleplug's actions.

btleplug 0.5.5 (and earlier 0.5) suffers from a kernel ABI incompatibility that has gone unnoticed until now; see deviceplug/btleplug#383. Fix has been proposed for btleplug, but anyway 0.5 is really old; consider upgrading to latest (which has an entirely different API, unfortunately).

btleplug confirmed that old versions are not maintained, so I cleaned up local hacks and made a proper fork to not forget about it. Feel free to take or ignore #11.

(I don't think that pointing this curiosity out in the Linux mailing lists would be worthwhile even though the problemo came to be from a kernel patch.)

Thanks for the patch! I’m averse to have git dependencies as then publishing crate isn’t possible as far as I know.

I’ve post-poned updating btleplug as the D-Bus implementation in 0.6 does not support passive scanning. Bluer could be an option that might allow using passive scanning, but both do indeed require a rewrite.
