Firmware version onboard

[darkom-ltu]

Hello,

Is it possible to read which firmware version is currently on PX4FLOW?
I notice performance degradation when I upload the newest firmware with exactly the same parameters I had on the one which sensor came with.

I also wonder if it would be possible to get 'hex' out of the PX4FLOW sensor out as a 'backup' and flash another sensor with it? I currently have 1 working on older firmware which works well and 2 on the newest one with much worse low light performance, even all parameters are the same.

Can you check that EXPOSURE_MAX and BRIGHT params are the same as before?

I was wondering about the version currently available via QGroundControl, so I grabbed it from AWS and ran:

cat px4flow.px4 | strings

This gave the following info:

  "git_identity": "1bb4e50-dirty", 

So apparently that build is from code submitted August 2017.
