Hi
I made 8 light bars for our band.
Each one has 120 leds and an own ESP32.
I wanted to have 1 master and the 7 other should be synced to him.
The problem is, only 3 of the other devices can connect to the master network.
The other 4 wont connect and create their own network.
Did i miss something, is there a limit of devices in one network?
Do they just not sync are are you saying they won’t all connect to the WiFi?
If WiFi, then there’s an issue with your WiFi router/network.
They wont connect to the wifi that the 1st (master) is creating.
I forgot to mention, when more than 4 are switched on, (1 master 3 “slave”)
even a smartphone or laptop cant connect to the master.
The way sync’ing works is that they all need to be on the same WiFi network and then they can pass various protocols you specify to sync. They won’t connect to builtin AP of a single board.
I know I can connect at least one to another’s AP.
Why not just buy a cheap router and use that to create/manage the network? You don’t have to have it connected to the internet. Just use it local.
This is not true, you can sync wleds in the middle of the forest with no other Wi-Fi around if they each have their own esp32 board.
I have the same issue as OP.
Did you ever solve this issue? I’m having a similar situation. I’m not quite sure what you meant when you were able to confirm that the non-responsive esp32 boards were unable to connect to the master wi-fi. I don’t see how to confirm such a thing. I just know I turn on send on one of them and receive on all the other ones and only a few of them are able to successfully sync up.
I never went into each individual slave and made them connect to the master wi-fi. It just does it automatically I guess (?).
you can use ESPNow sync. I think number of clients for an ESP in AP mode is limited in WLED.
