I have been working with Linux for a year now, but there are still some aspects of Linux that I'm struggling to understand.

Currently, I am facing an issue related to setting the transmission power (tx power) of Bluetooth. I have attempted various methods and searched through multiple forums, but I have yet to find a solution.

Here are the steps I have taken so far:

  • I used the hciconfig command to identify my Bluetooth device.

  • Next, I attempted to change the tx power using the following command:

    sudo hciconfig hci0 inqtpl 10

To verify if the tx power had indeed changed to 10, I ran the command:

  sudo hciconfig hci0 inqtpl

The tx power remained the same as it was before the attempted change.

How can I solve this?

    Are you sure your Bluetooth chip supports level 10? Commented Jul 6, 2023 at 7:58

    Yes, even I tried with lower values till 1. The value is constant after setting Tx power that means it didn't change. Commented Jul 7, 2023 at 11:50
