Hello, this is my first post here. I am looking for ideas and general direction. I have ESP32s networked with ESP-NOW. The ESP32 send and receive data from a central hub. This central hub is connected to a server computer via USB. The computer sees the ESP32 connection as a serial ...
After that, simply click the connect button. It may take a while, but then the status of the elements should change accordingly to what is shown in figure 3, indicating the connection was established and now we can send data to the websocket server. ...

here the while loop breaks before getting all the data from server don't know why.. check if you can understand this problem. VojtechBartoska removed the Status: Awaiting triage label May 17, 2022 Collaborator SuGlider commented May 17, 2022 Try this code: Xinyuan-LilyGO/LilyGo-T-Call-S...
