I remember this update, it wasn’t working over the air for some people and me either.
We are now at V1.18.2 so, why not updating?
Attention, you need to update Luban too, there were significant firmware changes in 1.18 and Luban 4.9.1, this means your old gcode would not work anymore.
Edit: Sorry I thought you are on 1.8…
