How to query PX4 version using MAVSDK

[YalamareddyChaitanya]

I have used MAVSDK Info plugin to query PX4 version that I am using. Info plugin gives PX4 version 1.13.0, But the exact version of PX4 is 1.13.0beta. Is there any another way to query the exact version of PX4?

Is the information you need not in this struct somewhere?

@julianoes Yes, It has some information. But If git tag of PX4 firmware is v1.13.0-beta*, Info plugin gives version data until v1.13.0 without beta as flight_sw_patch version in Version struct is an Int. I could use git hash instead of tag. Some how Qgroundcontrol managed to query the PX4 version including beta using Additional version type.

I guess the information should be somewhere and we need to decode it correctly in mavsdk.

https://github.com/PX4/PX4-Autopilot/blob/ce609144b0b8058cf4d05dac691c36c4f0a4ffd0/src/lib/version/version.c#L48-L59

MAVSDK/src/mavsdk/plugins/info/info_impl.cpp

Lines 106 to 108 in 7ebcc68

	_version.flight_sw_major = (autopilot_version.flight_sw_version >> (8 * 3)) & 0xFF;
	_version.flight_sw_minor = (autopilot_version.flight_sw_version >> (8 * 2)) & 0xFF;
	_version.flight_sw_patch = (autopilot_version.flight_sw_version >> (8 * 1)) & 0xFF;

Maybe this information is enough for you to figure it out and make a pull request? I'm pretty busy at the moment and can't look into it in detail I'm afraid.
