If not just using a webpage as a above.Dear all.
What I am trying to do is obtain data from a esp32 and pass to RPI 5 in attempts to display the data on a large screen.
They are still esp32 and the PI are not connected approximately 50ft away.
I use Esp32 now to send data to another Esp32 and display on a smaller screen 3 inch 7 segment led.
But I want to display on a much larger display and my thoughts were a large tv using hdmi.
I need to collect the data via Bluetooth as serial is in use for esp32 now.
And display that data on a large tv
It’s only one word to be displayed so not a lot of data.
A standard method is to setup an MQTT seever on the Pi5.
Setup MQTT publishing on the ESP32 and have it send it values to the MQTT Server. (Usually Wi-Fi, no doubt a BT connection would work if you know how)
You can then read the data from the MQTT Server by subscribing to it and do whatever you need to.
You can then repeat this if you add any more ESP32 for whatever reason.
