  those for soft spi are ok?

  var sx = new SPI();
  sx.setup({ sck:D0, miso:D4, mosi:D5 });
  sx = require('SX127x').connect({spi: sx, cs: D2});
  

  regards,

  With softspi I got the hello back in the console :)
  connected a logic analyser and only got this repeated.... (could you take any conclusion from this)
  one question, I noticed the module doesnt have any dependencies.
  how do i work with the module locally (on command line)?
  "wget SX127x" and use require('./SX127x').connect doesnt seems to work.

  Gordon thanks for the reply, and congrats I noticed the module also is yours :) really great work.

  Yah the module is powered (checked 3.3v on the module). Powered from pins between D4&D5 on ESP.

  Is It possible to use the gpios 6/7/8/11 for spi? How about reset pin?

  regards

  if anyone is interested, rfm95 manual attached

  all new with espruino on esp8266.

  found the module https://www.espruino.com/SX127x same chip in the RFM95.

  RFM95 (868mhz) pinout attached:

  Really nothing happens here, the callback is not called.
  How to check if radio is working? how to debug those?
  thanks for any help.

  by the way does anybody knows how to avoid showing crap chars when reseting the board (before espruino logo).

  connections:

  ESP <--------------> RFM
  CLK (GPIO14/D5)  <-> SCK
  MISO (GPIO12/D6) <-> MISO
  MOSI (GPIO13/D7) <-> MOSI
  CS (GPIO15/D8)   <-> NSS
  ??? <-> RESET
  

  code:

  function loraHandler(err, data){
    if (err) console.log("RX ERROR");
    else console.log("RX>", data);
  }
  
  console.log("all starting on ESP8266...");
  SPI1.setup({ sck:D14, miso:D12, mosi:D13 });
  var sx = require("SX127x").connect({spi: SPI1, cs: D15});
  
  // Until DIO0 line irqs are implemented we need this:
  setInterval(function() { sx.onIRQ(); }, 100);
  
  var config = { rxContinuous : true };
  sx.setRxConfig(config);
  
  sx.rx(loraHandler);
  
  setTimeout(function() {
    console.log("going standby");
    sx.standby();
  }, 10000);
  
  // vim: ai ts=2 sts=2 et sw=2 ft=javascript
  

  and the output:
