Does not support 25Hz scanning frequency

LMS1xx/src/LMS1xx_node.cpp

Line 75 in e529960

if (cfg.scaningFrequency != 5000)

I suggest the change to:
if (cfg.scaningFrequency != 5000 && cfg.scaningFrequency != 2500)

Yes, I wondered about that too!

I remember vaguely trying to change this, but If my memory serves me right the object that is used to interface to the lidar breaks if one tries a different frequency. More code than this part needs to be updated. Too long ago to remember though.

Did you succeed to make it work at the end?

Sadly no, me and a friend dug into it and decided to build our own node to throw away un-needed measurments instead. It surely is possible but we suspect it might be easier to build the interface code from scratch if you want it to do something else... :/

So we kept ours at 50Hz.

Ok, thank you very much 👍
