Espruino on the Heltec/TTGO/Lolin/WEMS esp32 lora board

The RST pin is important in the Wifi Kit 32 board, I would assume it is in your case as well.

 I2C1.setup({scl:D15,sda:D4});
 
function start () {
    // put your startup code here. 
}

g = require("SSD1306").connect(I2C1, start,{rst: D16});

There are a series of NRF classes in the reference documents, that I believe the ESP32 uses for Bluetooth. I'm not sure how much of it is fully complete as its a feature in development.

I don't have a LoRa board, so I cannot help you with that one.
