• Advertising custom UUID from Puck.js

  but if you just want to tell the devices apart, MAC address is definitely the best!

  It was thank you so much for the reply , however as you said I managed with the MAC address which is even easier, now I just need to work out how to get Esphome to understand the advertised battery percentage from the pucks , but that's a topic for another thread .

  Thanks again

  And I take it each puck has a unique one ? In which case this is great, I can use that without any addition to the code. Thanks for your help

  MAC address would be great , but doesn't it randomly change from time to time ? If not then I can definitely use the MAC address. I will be using ESPHome with a Bluetooth esp as a base station device that sends the presence back to Home assistant .

  You can see MAC address as one of the 3 options

  Hi I'm sorry for reviving this post, I can create a new one if required. I'm trying to do a similar thing by using a UUID as a way of distinguishing between two pucks to use as presence detection for home automation. I understand I could setup up something like the ibeacon service but all I need is a UUID that doesnt change for each puck. I tried creating a 128 bit UUID using

  date | md5sum
  

  and then seperating the result like you suggested above

  NRF.setAdvertising([
    [
  0x13,0x19,0x00,0x01,0x07,0x6e,0xe3,0xac,­0xd3,0xc5,0x1b,0xbd,0xf7,0x28,0x83,0x6c,­
  ]]);
  

  , but this didnt work and I had to hard reset to get it back programmable , did I need to add a service similar to above ?

  NRF.setServices(undefined, {
        uart : false, 
        advertise: [ 'ABCDABCD-ABCD-ABCD-ABCD-ABCDABCDABCD' ]  
  });
  

  I'm very new to this it been a bit of a learning curve today to understand how it all works.

  is this the best way to achieve what I want ?

  thanks in advance
