hey Roger
I'm sure it is a python problem.
not foss, but I'll make a little sample. it involves tk, which may be relevant. or the problem is calling pub from sub handlers.
I split the app (one memory space) into two, one that has both sub and pubs, and one that just has subs and tk things.
which is having its own issues, nother post coming up.
Hi Carl,
It's very difficult to say without knowing the details. Does e.g.
`mosquitto_pub` work fine in the same situation? If that works, then
it's like the Python code that is at fault. If your project is open
source, perhaps you could point us at it in case somebody wants to
help out.
I would always recommend using an up to date version.
Regards,
Roger
