Strange eventcodes in onZeroTierEvent

In MainActivity, start is called and MyZeroTierEventListener is passed. Function returns 0. All is good.

Then, in the callback:

I am getting strange event codes.
starting with 200 with no id,
then 201 with an id,
then 240, 3 times with distinct ids for each.

None of these event codes seem to correspond to known values.

Thanks a ton!
