RAK8211-NB BC95 support

Thanks - I'm looking into that with Rak at the moment. I believe it must have been swapped between the 8211-G and 8211-NB.

Would it be possible to post up your code?

This should be a good start I hope - it seems to work until CFUN=1 for me, but that's not too surprising given I seem to have a different (BC35) module on the board RAK sent me, and there's no NB-IoT service here anyway.

function atcmd(cmd,timeout) {
  return new Promise(function(resolve,reject) {
    var data = "";
    at.cmd(cmd+"\r\n",timeout||1000,function cb(d) {
      if (d===undefined || d=="ERROR") reject(cmd+": "+d?d:"TIMEOUT");
      else if (d=="OK") resolve(data);
      else { data+=(data?"\n":"")+d; return cb; }
    });
  });
}


var at;
var iTracker = require("iTracker");

iTracker.setCellOn(true, function(usart) {
  console.log("cell now on");
  usart.setup(9600, { tx:D20, rx:D12 });
  at = require('AT').connect(usart);
  at.debug(true);
  // based on https://ansi.23-5.eu/2017/06/nb-iot-bc95-arduino/
  atcmd("ATE0").then(function(d) { // echo off
    console.log("Set the communication band in this case 900Mhz");
    return atcmd("AT+NBAND=8");
  }).then(function() {
    console.log("Sets the APN (Access Point Name)");
    return atcmd('AT+CGDCONT=1,"IP","NBIOT.Telekom"');
  }).then(function() {
    console.log("Connect to the IoT Core");
    return atcmd("AT+CEREG=2");
  }).then(function() {
    console.log("Power on the module");
    return atcmd("AT+CFUN=1");
  }).then(function() {
    console.log("Force the module to connect to the network");
    return atcmd('AT+COPS=1,2,"12345"');
  }).then(function() {
    console.log("Wait 30s");
    return new Promise(r=>setTimeout(r,30000));
  }).then(function(d) {
    console.log("Hopefully connected!");
  });
});
