@canisLupus1313 OK, I have uploaded my firmware. Please have a look. And I also tried to change the name to "Thread BLE" , but the problem still exists.

from ot-nrf528xx.

It looks like that it has not been implemented yet.

@L1amaGod Currently the only platform that has the TCAT functionality implemented fully is NCS please refer to https://github.com/nrfconnect/sdk-nrf .

@canisLupus1313 But I can not update to the newest sdk version which includes TCAT features. I typed west update to update my ncs, but it could only update to "ncs-zephry: v3.4.99-ncs1-1" which didn't have TCAT features.

How can I update to the newest version?

from ot-nrf528xx.

@L1amaGod try initialising the west work space from nrf repo
west init -m https://github.com/nrfconnect/sdk-nrf
Then do west update and build the cli sample with:
west build -b nrf52840dk_nrf52840 nrf/samples/openthread/cli/ -p always -S="tcat"

@canisLupus1313 Thank you so much! It works. And then could you teach me how can I make my OTBR commission to this ble_tcat thread device by using this ble_tcat feature?

from ot-nrf528xx.

@L1amaGod On the DK yu should invoke ot tcat start via cli.
And use TCAT commissioner currently we are working on options to deliver but You can look at:

https://github.com/pjasinski990/bbtc
or
https://github.com/arnulfrupp/TcatClient

from ot-nrf528xx.

@canisLupus1313 Thank you!So based on current github code, is it possiable for me to do a test about connecting to a tcat device? Because I tried to install bbtc and connected to a tcat device. I succeed in scanning device but failed in connecting. What's wrong with it?

from ot-nrf528xx.

@L1amaGod Have you changed the provided certificates? Or anything in the code?

Enter 'help' to see available commands or 'exit' to exit the application.
> scan
Found devices:

1: Thread BLE - E4:08:FD:3E:97:1E

Select the target number to connect to it.
> 1
Selected  E4:08:FD:3E:97:1E: Thread BLE
Connecting to E4:08:FD:3E:97:1E: Thread BLE
Setting up secure channel...

In my original one I can also spot that BLE device is named differently Thread BLE vs NCS DUT.

from ot-nrf528xx.

@canisLupus1313 No, I have not changed the provided certificates. The only thing I changed is name = "bbtc client" in file pyproject.toml.
Because I failed in poetry install at the begining. The logs is like below:

Then I changed name = "bbtc client" to name = "bbtc" in file pyproject.toml, and it looked installing successfully.

So, is that the reason I can not connect device? Or did I forget to do something neccessary, I just run poetry install and then poetry run python3 bbtc.py --scan.

from ot-nrf528xx.

@L1amaGod I was asking about the firmware that you have. Since name of the device is changed there.
And the default certificated are compiled into the device.

@L1amaGod
zephyr.hex.zip
Please try this firmware.
And Can You upload your .config file from zephyr build repo?

Of course.

@canisLupus1313 Maybe I found the reason. I used to build cli project with west build -b nrf52840dk_nrf52840 after I modified file prj.conf, but it failed in tcat connection.
Now I build project with west build -b nrf52840dk_nrf52840 nrf/samples/openthread/cli/ -p always -S="tcat" as you said without modifying file prj.conf, and now it works normally.
So, if I want to build project with normal command west build -b nrf52840dk_nrf52840, how should I modify the conf file prj.conf?

@L1amaGod
Good reference would be reading about snippets https://docs.zephyrproject.org/latest/build/snippets/index.html

The one that is actually enabling the TCAT is https://github.com/nrfconnect/sdk-nrf/blob/main/samples/openthread/cli/snippets/tcat/

from ot-nrf528xx.

@L1amaGod have You had a chance to read the above docs? do You have any more questions?

Closing stale issue.
