I'm in a world of hurt and don't know how to get out of it.
I've built a set for a theatre production of Newsies, which consists of three two-story towers. Each of six total openings in the towers have servo driven, Feather Huzzah controlled projection screens that move up and down independently throughout the show. They are also battery powered, since the towers have to move around the stage.
Our show opens tonight, and nothing is working reliably. Yesterday morning, I got all six screens to work, but then at last nights tech rehearsal, I had connection dropouts and occasional repetitive blasts of Serial transmissions from what appears to be one of the chips stuck in the message received callback, which fires off the Serial.print call "Start Here: Message received from..." over and over. I'm using the "Painless Mesh" library from BlackEdder: https://gitlab.com/BlackEdder/painlessMesh/tree/master
I've tried everything mentioned all over the interwebs that I can find - yield();, setting the watchdog to 8 seconds, adding a 1000uf cap on the battery input. The boards were REALLY wonky before adding the yield(); I instead had ESP.wdtfeed - when I added yield(); the boards flipped out, but when I removed the wdtfeed and kept yield, they all worked fairly well. But there are still too many hiccups to feel comfortable running them for the show with an audience.
I am controlling the AP with Touchdesigner, a video production software that has integrated serial out communication. The Touchdesigner side of things works just fine. The code below is what's on the AP, and then one of the six that's on the nodes. The only difference in the code on the nodes is the value used to stop the continuous servo andwhich char to read from the packet sent to all Nodes from the AP. For example, 111111 means all screens up, 000000, all down, 111000, the first three up and last three down, etc. 333333 and 444444 is for my IR tracking LEDs relay triggering. I haven't got to that part yet.
I know this is long, but I'm begging for any help at this point - like I said, show opens tonight, and I'm at work all day =(

ANY Advice is appreciated. Let me know if any of the code (which I never commented) doesn't make sense. Thanks!
