  • 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:
