Hi Gurpreet,

 

If you are using BlueZ 5.48 then, as stated in the instructions you don’t need to set the static address manually.

Instead you should just do:

 

sudo btmgmt --index 0

[hci0]# auto-power

 

Regards,

 

Carles

Hi Carles,

 

I should have mentioned that I did see those instructions at zephyr and have already updated my  /lib/systemd/system/bluetooth.service file. 

Thats the only real change I've noticed between the blog instructions and the zephyr instructions. 

 

Is there something else that I need to do as well?

Hi there,

 

If you are using a recent version of BlueZ then the sequence that you need to do is different from what’s on that blog post.

Here are updated instructions:

I will update the blog post to reflect this since I see it’s still being used as a reference.

Subject: [Zephyr-users] Unable to set Static Address on nRF52 using Zephyr v1.11.0

 

Hi,

I've been chugging along nicely with Zephyr v1.11.0 and the nRF52DK so far, being able to get it to scan and advertise using the hci_uart sample code and my Linux (ubuntu) computer. 

My linux is on BlueZ 5.48 and kernel ​4.15.0-22. This setup is just to get the ball rolling until we get sample boards from our manufacturer. 

I have run into an issue where setting the address on the chip is being rejected. 

I came across this post in the forum, but have been unable to find any clean resolution for it. 

For advertisements, you can see the all zero source mac address in the attached PCAP. 

Interestingly, the same error persists even when following the blog post on how to use the BLE controller with linux's BlueZ. (Step 5 in particular) ​

--- btmgmt
[hci1]# static-addr FF:02:03:04:05:FF
Set static address failed with status 0x0b (Rejected)
[hci1]# 

--- btmon
@ MGMT Command: Set Static Address (0x002b) plen 6 {0x0004} [hci1] 9585.454699

@ MGMT Event: Command Status (0x0002) plen 3 {0x0004} [hci1] 9585.454706
 Set Static Address (0x002b)
 Status: Rejected (0x0b)

To bring up the chip, I ran:

~ 11:49:30>sudo btattach -B /dev/ttyACM0 -S 1000000 -P h4
Attaching Primary controller to /dev/ttyACM0
Switched line discipline from 0 to 15
Device index 1 attached

The btmon log after this is in the attached txt file. 

Do you have any tips or suggestions on what I could do? 
Essentially, I would like to be able to program the BLE chip with a MAC address that uses the Mist OUI. 

Thanks in advance,

Gurpreet

Hi Carles

Hi Gurpreet,

 

I do not know why you get that behavior. Typically BlueZ should detect that this is an LE-only controller with no public address and would assign one to it.

Maybe it’s because you seem to have more than one controller? you are using hci1 on your btmgmt log.

 

I just tested this locally by doing:

 

sudo btattach -B /dev/ttyACM0 -S 1000000 -P h4

Attaching Primary controller to /dev/ttyACM0

Switched line discipline from 0 to 15

Device index 0 attached

 

and then:

 

$ sudo btmgmt --index 0

[hci0]# auto-power

Found controller with index 0

[hci0]# advertising on

hci0 Set Advertising complete, settings: powered bondable le advertising secure-conn static-addr

 

And in btmon it clearly set a random static address:

Hi Carles

 

Yes. I've been doing that but the Mac address comes up as all zeroes. Which is my original  problem. 

So how do I set a Mac address? Or why is it all zeroes?

Hi Carles

Well, I am not sure if it will be an issue or not, I was just suggesting changes since  I cannot reproduce the issue myself.

If you have your own OUI then you need to set and use a public address, not a random static one. To set a public address you need to use a Vendor Specific command:

https://github.com/zephyrproject-rtos/zephyr/blob/master/doc/subsystems/bluetooth/hci.txt#L408

 

I believe you can do that with “hcitool cmd”, which allows you to send an arbitrary HCI command to the controller.

Hi Carles

 

Hmmm. I can try disabling my laptop's Bluetooth and attempt this again. 

But would that mean, when I have my actual boards, this won't be an issue?

 

Also, based on what you're saying, however, is there no way to specifically assign an address of my choosing? We have our own OUI, and want to use that for the implementation.
