  • A headset does connect to your phone via bluetooth classic to stream music, not BLE. The battery level might be offered via BLE but that is not always the case. – Michael Kotzjan Dec 09 '21 at 05:24
  • So Can I get headset battery level using ble and HOW ? There are many apps in play store which shows battery percentage of connected bluetooth device (headset) – Harsh Dec 13 '21 at 15:25
  • Please provide enough code so others can better understand or reproduce the problem. – Community Dec 13 '21 at 17:14
  • @Harsh but are the using BLE or bluetooth classic? Have you tried using a generic BLE scanner such as [nRF Connect](https://www.nordicsemi.com/Products/Development-tools/nrf-connect-for-mobile) to see if the headset offers a standard battery service? – Michael Kotzjan Dec 15 '21 at 09:02
  • The tws i used were nothing ear 1, which has a dedicated app that shows battery percentage of both buds as well as case, when I used nRF Connect, it says that it is LE only device type and I can see list off UUIDS. – Harsh Dec 15 '21 at 15:35
