Here is the HTML version of the steps to modify parameters of the Bluetooth ath9k module:

Modify parameters of the Bluetooth ath9k module in Linux

To modify the parameters of the ath9k kernel module that controls your WiFi/Bluetooth chipset, you can follow these steps:

1. Edit the module configuration file. For example to enable Bluetooth antenna diversity:

   sudo echo 1 > /sys/module/ath9k/parameters/bt_ant_diversity  
   

2. To make the change permanent, you must edit the file /etc/modprobe.d/ath9k.conf:

   sudo nano /etc/modprobe.d/ath9k.conf
   

3. Add the line with the desired parameter, for example:

   options ath9k bt_ant_diversity=1
   

4. Save the file and reboot for the changes to take effect:

   sudo reboot  
   

5. Verify that the new value has been applied:

   grep -H '' /sys/module/ath9k*/parameters/* | grep bt_ant_diversity
   

You should see bt_ant_diversity:1 now.

This way you can configure different parameters to test improvements in connectivity, stability, speed, etc. Consult the ath9k driver documentation for more details on the available parameters.
