Intel 8265 set Bluetooth transmit power

[zk97]

Is there any command to set transmit Intel 8265 bluetooth transmit power from linux aarch64 system. I’ve tried “hciconfig hci0 inqtpl XXX” command but it didn’t change anything.

Hello zk97,

Thank you for posting on the Intel® communities. I understand that you have some questions about the Intel® Dual Band Wireless-AC 8265.

In order to better assist you, please try the following:  

1. Are you working on a project?

2. Is this the original adapter that came pre-installed on your computer or did you change/install the adapter to this one?

3. Have you checked with the laptop or motherboard manufacturer to confirm that this feature is supported by the BIOS?

4. Can you provide more details about what want to do?

1. Yes, we have developed a device which uses 8265.

2. We use original adapter. Our system is custom made so we install in ourself.

3. We use aarch64 linux system running on Nvidia Jetson Xavier NX. Intel bt chips are supported by nvidia linux kernel L4T but I don't see support to change transmit power.

4. We have both wifi and bt working properly. But we need out device to pass FCC tests. And for that we need to transmit data bt data at max transmit power and duty cycle. So I'm look for a command/setting to change bt transmit power from linux.
