ESP32 Serial2 setup and try to connect to RN2384A

Hi all

I'm trying to setup an serial connexion to the RN2483A to achieve an LoraWan test with TTN, like this exemple on Espruino site with no result. I've connect TX/RX from @DrAzzy plate to RN2384A TX/RX, power and try :

var RN2483 = require("RN2483");
Serial2.setup(9600, { tx:D17, rx:D16 });
var lora = new RN2483(Serial2);
lora.getStatus(function(x){console.log(x­);});

and get this result:

{ "EUI": undefined, "VDD": NaN, "appEUI": undefined, "devEUI": undefined,
  "band": undefined, "dataRate": undefined, "rxDelay1": undefined, "rxDelay2": undefined, "rxFreq2_868": undefined }

So I'm trying first to get some console.log from the Serial2 on this ESP32 MCU board .

I wired GPIO16 and GPIO17 and try this :

Serial2.setup(9600, { tx:D17, rx:D16 });
Serial2.on('data', function(data) {
  console.log('Serial2: ', data);
});
Serial2.print('/// Hello UART ///');

Well... with no result too :(
Does someone succeed in this project?
