  Thanks @Gordon!
  I guessed it could be a limitation also because that bulb has a lot of custom UUIDs.
  I will try the battery trick but in this case i think it will be better to use array index as i already did, so i am sure i will point to the right service/characteristic.

  No that's not the problem, because i get the error on line 8 (of the "original" code, the code i posted is the workaround)

  return gatt.getPrimaryService("fff6fe25-469d-42bc-9179-b3a093f19032");

  Hi all,
  since i got my 2 Pucks, i am doing some experiment with BLE devices.
  I was tempted and i've bought an Awox BLE Color Bulb, but i'm having problem getting Primary Services.
  I am only able to use the first Primary Service "33160fb9-5b27-4e70-b0f8-ff411e3ae078" and its characteristic "217887f8-0af2-4002-9c05-24c9ecf71600", where sending 0 or 1 will turn the bulb off/on.
  There are at least 2 other Primary Service (discovered with nRF Connect), 1 for warm light brightness and 1 for RGB lights.
  Trying to use one of these, i receive the error on command gatt.PrimaryService("fff6fe25-469d-42bc-9179-b3a093f19032")

  Uncaught Error: Unhandled promise rejection: Error: Too many custom UUIDs already
  

  If i try gatt.PrimaryServices(), i get this

  [
    BluetoothRemoteGATTService {
      "uuid": "0x1800",
      "isPrimary": true, "start_handle": 1, "end_handle": 11 },
    BluetoothRemoteGATTService {
      "uuid": "0x1801",
      "isPrimary": true, "start_handle": 12, "end_handle": 15 },
    BluetoothRemoteGATTService {
      "uuid": "0x180a",
      "isPrimary": true, "start_handle": 16, "end_handle": 30 },
    BluetoothRemoteGATTService {
      "uuid": "0x0000[vendor]",
      "isPrimary": true, "start_handle": 31, "end_handle": 49 },
    BluetoothRemoteGATTService {
      "uuid": "0x0000[vendor]",
      "isPrimary": true, "start_handle": 50, "end_handle": 64 },
    BluetoothRemoteGATTService {
      "uuid": "0x0000[vendor]",
      "isPrimary": true, "start_handle": 65, "end_handle": 85 },
    BluetoothRemoteGATTService {
      "uuid": "0x0000[vendor]",
      "isPrimary": true, "start_handle": 86, "end_handle": 65535 }
   ]
  

  Actually, yesterday i could correctly see at least the first PrimaryService UUID ("33160fb9-5b27-4e70-b0f8-ff411e3ae078"), so the only way i found to access other services is using gatt.PrimaryServices() and then use the array index of the service i need instead of using for example gatt.PrimaryService("fff6fe25-469d-42bc-9179-b3a093f19032")

  This is the portion of the (dirty) code i am using, just for testing purpose

  function connectToBulb(){
    console.log("Connecting to bulb...");
    
    NRF.connect("98:7b:f3:77:a4:23").then(function(g){
      connected = true;
      digitalPulse(LED3, 1, 500);
      gatt = g;
      return gatt.getPrimaryServices();
    }).then(function(service){
      return service[4].getCharacteristics(); // Equals to "fff6fe25-469d-42bc-9179-b3a093f19032"
    }).then(function(c){
      c[1].writeValue(0x7F); // Equals to "d8da934c-3d8f-4bdf-9230-f61295b69570"
    });
  }
  

  while using gatt.PrimaryService("fff6fe25-469d-42bc-9179-b3a093f19032") or gatt.getCharacteristic("d8da934c-3d8f-4bdf-9230-f61295b69570") are returning me the mentioned error.

  Am i doing something wrong?

  Yes, my "dirty workaround" was to add +1 hour in the code, more or less like you suggest, while creating the Date object.
  Didn't think about using setTime to make it "permanent".

  The Puck has its own RTC, and it's "synced" everytime you upload something from your pc.
  You can use if for example as an alarm clock (do something at given date/time), that's great!

• Error when saving to flash

  I have the same issue if "Save on send" is enabled.

  function tempTo2a6e(temp) {
    var f = parseFloat(temp.toFixed(2)) * 100;
    if (tempTo2a6e.buf === undefined) tempTo2a6e.buf = new Uint8Array(2);
    tempTo2a6e.buf[0] = f & 0xff;
    tempTo2a6e.buf[1] = f >> 8 & 0xff;
    return tempTo2a6e.buf;
  }
  
  NRF.on('connect', function(){
    digitalPulse(LED2, 1, 250);
  });
  
  NRF.setServices({
    0x181A: { // Health Thermometer
      0x2A6E: {  // Temperature
        readable: true,
        value : tempTo2a6e(E.getTemperature())
    }},
    0x180F : { // Battery Service
      0x2A19: {  // Battery Level
        readable: true,
        notify: true,
        value : [Puck.getBatteryPercentage()]
  }}});
  
  setInterval(function(){
    NRF.updateServices({
      0x181A: { // Health Thermometer
        0x2A6E: {  // Temperature
          value : tempTo2a6e(E.getTemperature())
      }},
      0x180F: {
        0x2A19: {
          value : [Puck.getBatteryPercentage()]
        }
      }
    });
  }, 60000);
  

  After few seconds, i get this error:

  Writing...ERROR: Prompt not detected - upload failed. Trying to
  recover... Compressed 32000 bytes to 956 Checking... Flash Magic Byte

• Is it possible to set more than one service ?

  @dklinkman your code works very well! Thank you!

  Great find @dklinkman! I will try this tonight!
