PUCK Ble HID keyboard

Thank you @allObjects. I have this working now. Initially it had the same error, but after increasing the setTimeout from 1 to 50, it worked in the console. However, it would fail if anything was added to FIFO string whilst a send was in progress, but increasing the setTimeout to 100 has cured this.

To get it to type the string over bluetooth I had to get rid of all the console.logs. Here is the code I have working now:

function onInit() {
  var kb = require("ble_hid_keyboard");
NRF.setServices(undefined, { hid : kb.report });

// setup of you convenience hidKeyBoardObject... (here or later)
var hidKBD = ( { string: ""
                
, type: function(s) { 
    this.string += s; 
    if (this.string.length == s.length) { 
                      
                      
      this._send(this.string.charAt(0)); // get first char out
  } }
,   _send: function(c) {
       // console.log("About to send char",c);
        setTimeout(function(_){
            kb.tap(kb.KEY[c],0,_._sent.bind(_)); },100,this);
    }
,   _sent: function() {
        //console.log("Char",this.string.charAt(0),"has been sent / tapped");
        this.string = this.string.substring(1);
        //console.log("Left to send / tap is",this.string);
        if (this.string.length > 0) {
          //  console.log("Since length of this.string //is",this.string.length
  //                     ,"and is > 0, next char 'in line' -"
                       //,this.string.charAt(0)," - has to be sent / tapped.");
            this._send(this.string.charAt(0));
        } //else {
          //  console.log("Since nothing is left to tap / send - all is tapped");
            //console.log("/ sent, (FIFO  is empty), nothing has to be done");
            //console.log(" anymore and  'logical recursion' stops/ends  here.");
        //}
    }
});

// setup and other code functions of yours (here or before hidKBD)
   // invoke your set up code as needed (init and getting connections)
   function startSend(){
     hidKBD.type("ABCCANNONBALL");}
  // hidKBD.type("XYZ");

	
setWatch(startSend, BTN, {edge:"rising",repeat:true,debounce:50});
