AX210 Bluetooth Advertisement

[rlorenzoleal]

To whom it may concern.

We're in the Bluetooth qualification process for a product using a AX210 as controller with BlueZ as host in an embedded Linux system.

To do so, we need to run certain tests and configure the device in specific modes.

Right now we're trying to configure specific advertisement modes by using hcitool and providing hci command directly to the AX210.

When we try to configure a advertising mode, we get an error with the response "Command Disallowed" (0x0c)

The specific command is

hcitool -i hci0 cmd 0x08 0x0006 00 A0 00 F0 01 00 00 C0 07 E8 D6 97 17 07 00

Here is the response from btmon

@ RAW Open: hcitool (privileged) version 2.22                                                                                                                         {0x0003} [hci0] 12820.341956

As you can see, my parameters are OK and conform to the command specification, however it gets rejected.

How can I configure this properly?

Thanks in advance

Hello rlorenzoleal,

Hello, 

I am recently working on a bluetooth low energy related project, and have similar issues on both AX201 and AX210, which are built-in adapter for two of our lab workstation. Both workstation use Ubuntu 22.04. We have tested reset adapter, reboot the workstation, but the problem persist.

We have tried few other commands and they works including HCI Command: LE Set Random Address (0x08|0x0005), excepts 

• LE Set Advertising Data (0x08|0x0008)
• LE Set Advertising Parameters (0x08|0x0006)
• LE Set Advertise Enable (0x08|0x000a)

You may observe the btmon.log, when I attempted to set BLE Adv. Data, Parameters, and Start Broadcasting, the adapters all replied Command Disallowed. I have a Realtek USB Dongle which can use the same script and accomplish the test on the same systems, as well as a Raspberry Pi 4. 

Thanks for the help

----------

After I read the log carefully, I noticed the hciconfig has set the Random Address and Set the Advertising prior my script. I suspect this is caused by the Ubuntu service.
