unable to make a simple BLE ....

great
thank you
I think you can post the code you post here as an easy to understand example
or even first code jsut flahs it
much more easy to understand ....

so see I understand it correct:

NRF.setAdvertising([
require("ble_eddystone").get("http://www.david.com"),
{

//this part is all the data I want to show using Hex , 
// can take examples from here https://www.bluetooth.com/specifications/gatt/characteristics/ - //right?
   0x180F : [NRF.getBattery()],
   0x1809 : [Math.round(E.getTemperature())]
  } 
],
//this is the default setting I can cahnge - right ? this is the only setting I can change from here 
{
   name  : "David",
   showName: true,
   discoverable : true,
   connectable : false,
   scannable : true,
   interval:100
});

so now:
I can see the device in bluetooth normal scan (see the name only and can't connect to it because of connectable : false)
I can see the data from "NRF-connect". which is what I want

Thank you so so much for this!

1. I'm tryin to play with this , and send more data
   just for the test I want to test this Hex(Got this from https://www.bluetooth.com/specifications/gatt/characteristics/)
   
   

Age org.bluetooth.characteristic.age 0x2A80 GSS
and add this to the code:

  {//here I put the HEX data -https://www.bluetooth.com/specifications/gatt/characteristics/
   0x180F : [NRF.getBattery()],
   0x1809 : [Math.round(E.getTemperature())],
   0x2A80 : "15"
  } 

in the NRF I can see battery\temp but not age -jsut Service Data without name - why?
just 20x2A80 0x31 0x35 (which is 15)
is it standart?

1. also can I set the time of the ble_eddystone for showing 2 websites?
   I did this

   require("ble_eddystone").get("http://www.david1.com"),
   require("ble_eddystone").get("http://www.Danny1.com"),
   

   if I want to make 1 min for website1 and 2 min for website 2?
   and meanwhile it will send data every 1 sec ?
   or I need to write a more complicated code for this ?

2. also the battery shown 3%
   is it because I'm connecting using USB to the V+ (5V) and not to the battery input?
   can I know what the voltage I'm using ? beacuse I saw it can be power on

   will work off of 2.5 to 16 volts
   can I measure the input?

Thanks,
