  Yeah, but theese are not complett devices with integrated ethernet port. So need to buy more things and solder and fail etc....

  Somebody did this with arduino:

  If somebody want to implement it to espruino it can be a good starting point. (I'll be happy if somebody implement this to espruno.)

  Hi,

  I'm trying to make work 2 esp32 modules with lora. But I did not succed.

  espruino version: 1v99.4103
  pinout (i hope it is good): https://cdn.hackaday.io/files/2699111547­82944/Heltec_WIFI-LoRa-32_DiagramPinout.­jpg

  For tx code i use:

  SPI1.setup({ sck:D5, mosi:D27, miso: D19 });
  
  var sx = require("SX127x").connect({spi: SPI1, cs: D18, rst : D14 });
  
  setInterval(function() { sx.onIRQ(); }, 100);
  
  var config = {
    freq: 868E6
  };
  
  sx.setTxConfig(config);
  
  sx.send("Hello", function() {
    console.log("TX done");
  });
  

  for the rx config i use:

  SPI1.setup({ sck:D5, mosi:D27, miso: D19 });
  
  var sx = require("SX127x").connect({spi: SPI1, cs: D18, rst : D14 });
  
  setInterval(function() { sx.onIRQ(); }, 100);
  
  var config = {
    rxContinuous : true,
    freq: 868E6
  };
  
  console.log('starting receiver');
  sx.setRxConfig(config);
  // enter receive mode
  sx.rx(function(err, inf) {
    // Error, or you get signal strength and data returned in an object
    if (err) console.log("RX ERROR");
    else console.log("RX>",inf);
  });
  

  I got no erros. On tx I got nothing. On rx I got this after upload:

  >starting receiver
  RX> { "snr": 82, "rssi": 82,
    "data": new Uint8Array([82, 82, 106, 57, 74, 161, 198, 62, 219, 7, 163, 65, 161, 130, 133, 51, 199, 36, 195, 5, 38, 5, 180, 150, 128, 35, 21, 91, 209, 28, 236, 12, 240, 80, 184, 230, 197, 134, 10, 22, 185, 154, 4, 0, 65, 225, 192, 10, 25, 14, 79, 117, 132, 194, 240, 160, 192, 83, 163, 48, 201, 0, 242, 12, 28, 228, 98, 16, 132, 5, 180, 231, 64, 201, 65, 82, 108, 14, 10, 232, 244, 114])
   }
  

  What I'm doing wrong?

  thanks

  Okay, the reset pin was wrong. Now, its working thanks.

  Anybody have an espruino example code with lora on a helltech board?

  Thanks! I downloaded your binaries.

  Do you have example code for?

  • rx and tx with lora module
    
  • bluetooth
    
    

  Yesterday I successfully created a code to drive the oled, but with this espruino version I got this:

  >WARNING: jshI2CSetup: driver installed, sda: 4 sdl: 15 freq: 100000,
  ERROR: jshI2CWrite:, slave doesn't ACK the transfer.
  

  And the the code worked yesterday does not drive with this espruino version.

  It works for me. (At least the first test.) I can connect (after a reset) with espruino ide. Thanks!
