Hi All, (UPDATE! There’s now an official implementation, so check that out! FluidDial/docs/ESP-NOW.md at main · figamore/FluidDial · GitHub ) (Update: How is this different than the websocket implementation mentioned below? ESP-NOW is radio-to-radio protocol of its own. So the flaky-ass wifi netwo…

You know the same dev as FigUI already made this wireless? [image] Uart bridge Hardware Development @Dreyfus I saw on the FluidNC Discord today that someone updated the FluidDial/CYD firmware to support a wireless connection. So, you wouldn’t need a bridge an…

Oh hah! Well I guess I’ll just enjoy the experience. Looks like he did a different approach with websockets, while I’m basically using a serial connection over the ESP-NOW protocol. It is broadcast based (latches to the MAC) so dealing with wifi networks is unnecessary.

[image] zerg32: I thought you cant use ESP-NOW and wifi at the same time ? They have to use the same channel (I handle that) but I haven’t had any issues in my initial testing. The nice thing is that this is a direct connection. In my video the webUI is going over my wifi router, but the pend…

which version/fork of fluiddial and fluidnc do you need ? I’m going to try it on my battery powered cyd pendant later today

I’m still finalizing a few things but will post the fork soon.

Hmm, I have this remote which uses ESP-NOW. I’ve used it to control WLED. Hmm. [Screenshot_20260514_190042_Amazon Shopping]

Ooh! I bought a sack of ESP32-C3’s because I thought I was going to make a virtual serial cable connection, until I realized I didn’t even need them. But esp-now is a party out of the box, so could be fun for lots of things… I’m glad I didn’t see that Wifi fork of FluidDial because I probably would…

I’ve updated the initial post at the top with the code, if you’re living dangerously. I don’t have a CYD so I only verified my code builds on it (not sure which one you have, so choose it with the _espnow profile.) Note that I’m making a lot of changes (server/client stuff) but will try to keep the…

Got some feedback from Mitch and making a few changes to potentially get this into something more widely useful, so might have a use for my sack of esp’s sooner than I thought! Basically broadcast mode for displays and unicast mode for pendants and the like. All outside of the evil WiFi kingdom!

I thought you cant use ESP-NOW and wifi at the same time ?

I’ve used the wifi connection to jackpot here. but later discovered some stability issues but that could be my wifi
