I'm using Expressif ESP32 dev boards and the PainlessMesh library. My nodes do an initial time sync, but after a while I've seen odd behavior where the calculated offset is negative... implying that the message came from the future.

I see in the PainlessMesh class definition a protected method called startTimeSync, which sounds similar to what I want. Is there a way to manually initiate a time sync request via PainlessMesh?

Thanks!

  • I should also note that I did see the mesh protocol time sync explanation, which is helpful for understanding what's happening behind the scenes, I just want to kick it off... https://gitlab.com/painlessMesh/painlessMesh/wikis/mesh-protocol#time-sync – Michael McMillan May 21 '19 at 22:47

Had a conversation with the folks over at Painlessmesh. There is a way, but it's not meant to be invoked directly:

    Whilst this may theoretically answer the question, it would be much better if you could include the essential parts of the linked page with the link for reference. Thanks! – anonymous2 Jun 25 '19 at 02:32
