Yes we went ahead on bluez. We are able to scan and make communication between BT server and client.

On the top of bluez we installed bluepy and after installing bluepy you will get some python source files with which you can test.

But for testing you can use bluepy files but later is is better to go with any other way like your reference link .

NOTE:

1. We didnt go further on this as we are having other priority tasks.

2. In some blog I read that bluepy gives support only for bluetooth 4.2 and not for 5.

Thanks alot for your quick response,

1. We are using Ubuntu (After basic testing will use AM4378 processor base linux system) as host device and nRF52840DK through USB as Radio

2. i) First Installed through $sudo apt-get install bluez libbluetooth-dev

ii) I didnt found command bdaddr, So Downloaded Bluez sources, compiled and installed (There were so many lib version mismatch issue, but some how installed)

3) Link for Query on forum Briefly describing how and what i did.

4) I can see my device as hci1 in hciconfig and using hci1 everywhere by disabling hci0 or giving as argument

5) Please can you comment on my 3rd point in last query (weather u proceeded with Bluez i) if yes can you share some docs or info. ii) if no whats the alternate)

Can you go through my query in other link and comment on it.

Lastly we can interact once, discuss the design part my mail murali@eternalrobotics.com

Thanks

which device/controller are you using..??

Are you using nrf52840 dongle or NRF52840 DK.

How did you install bluez.??

Can you see your device in hciconfig command. If yes send me the hciconfig logs.

Hi SanthoshN,

I have followed you steps and arrived at the same page and stuck here, Able to scan the devices.

1) Tried scanning Application from reference link. But stuck with error and not able to solve below error even after rigorous search

$ ./scan
Device ID 1
hci_inquiry: Operation not supported

2) Except few threads i could not found any tutorials or documentation to write the Bluez application to test it features.

3) Have you proceeded further with Bluez, If YES can you share any documents or links,

If NO whats the Alternate to use all features of BLE

Thanks and any inputs Highly Appreciated.

Hi Vidar,

I am having an issue which I raised a support ticket, can you go through that. Attaching the link in this.

NOTE: I am using NRF52840 DK and not USB dongle

Thanks for the update. Glad to hear that it works and that you have managed to to build the sample from Zephyr.

Hi,

Thanks a lot for your continuous support, we could scan the dongle now.

After upgrading my PC to ubuntu 18.04 and kernel to 4.15 I am able to scan using random BD address by flashing your zephyr.hex file.

However on raspbery pi Jessie we were unable to upgrade linux kernel beyond 4.14. After calling ll_addr_set from main.c we were able to proceed further.

We will be using this dongle to work as a BT5.0 gateway device.

Will let you know if we need any additional info.

Thanks a lot.

Hi,

[quote user="SanthoshN"]By running nRF connect on my PC and did a scan on it, where I didn't see the dongle random mac address but i'm able to get rest of the devices mac address.[/quote]

But were you able to discover the device?

[quote user="SanthoshN"][/quote]

This is the state of my device

The public address is 0 as expected, but the type should not be BR/EDR as it is an LE only controller. I suspect that the problem is related to this. It is not required to have a Public address. Did you have another PC to test this on?

1. It's possible to change the address, either by using the extended HCI commands or by modifying the sample code. However, you need to have a OUI for your company to assign public addresses, and I doubt it would fix the problem.

2. You can call ll_addr_set from main().

May I ask what you intend to use dongle for? Is it to test BT 5 features?

Hi,

Thanks for your reply.

I connected dongle to raspberry pi which is kernel v4.14 and bluez 5.48 and did the advertising on as you mentioned in the screenshot.

By running nRF connect on my PC and did a scan on it, where I didn't see the dongle random mac address but i'm able to get rest of the devices mac address.

Is the same zephyr.hex file you flashed on your dongle to test that which you shared with me..?.

This is the state of my device

santhosh@santhosh:~/zephyr$ hciconfig
hci0:   Type: BR/EDR Bus: USB
   BD Address: 00:00:00:00:00:00 ACL MTU: 27:7 SCO MTU: 0:0
   DOWN
   RX bytes:227 acl:0 sco:0 events:18 errors:0
   TX bytes:85 acl:0 sco:0 commands:18 errors:0

santhosh@santhosh:~/zephyr$ sudo hciconfig hci0 up
Can't init device hci0: Cannot assign requested address (99)

I gave many tries but nothing helped.

At present I am trying to compile the zephyr code.

1.Is there a possibility to change public mac address which is (00:00:00:00:00:00) to (xx:xx:xx:xx:xx:xx) default value in zephyr code.

2. If its possible can you tell me the exact process or the public mac address variable by which i can change the BD addr.

I think this can solve my issue.

Reply ASAP, im stuck on this from days.

Hi,

Have you searched the zephyr mailing list? In any case, there seems to be quite a few questions related to the address "issue". Only public addresses are displayed by HCI config.

Eg,

https://lists.zephyrproject.org/g/devel/topic/28047406

https://lists.zephyrproject.org/g/devel/topic/bluetooth_address_type/16760640?p=,,,20,0,0,0::recentpostdate%2Fsticky,,,20,2,240,16760640

I'm able to advertise using the random static address here, but I'm running ubuntu with kernel v 4.15.x and bluez 5.48 . Do you have PC with a newer version of Linux that you can test on?

:~$ sudo btmgmt --index n
[hci1]# auto-power 
Found controller with index 1
[hci1]# advertising on
hci1 Set Advertising complete, settings: powered connectable discoverable bondable le advertising secure-conn static-addr 
[hci1]#

Here is the device discovered in nRF connect. Notice the address type is Random static.

Is this hex is for nrf52840_pca10059 or pca10056. Ours is pca10059. Can you recheck and send me the hex file foe pca10059

I upgraded the kernel and tried to change the BD address

It is not updated and throwing the following error

pi@raspberrypi:~/bluez-5.50/tools $ sudo ./bdaddr -r 00:19:1D:6D:D9:DA

I belive there is a HCI command to set the address, please refer to the Zephyr documentation for more details.

With this hex I am able to see the device but its mac id is wrong.

Zephyr does not include any pre-compiled .hex files so the samples need to be built from source. I have built the example for you, but not verified if it works, see attached.

In Case ID: 211988 https://devzone.nordicsemi.com/f/nordic-q-a/37237/flashing-nrf52840-dongle-to-support-bluez

You mentioned to flash Zephyr BLE HCI_USB controller firmware on dongle.

Could you please point me to the FW as I was unable to locate the hex file.

You also mentioned to change the linker file. Please share the link of source code to change the FW start address.

Our goal is to connect dongle to raspberry Pi and use this dongle to perform BT operations instead of onboard BT chip using BLUEZ library.

Thankyou in advance.

Thanks for the reply.

I am using nrf connect desktop application to upload FW on my device.

After uploading fw on nrf52840, I am checking on linux terminal using hciconfig in which I am not able to find my device.

May I know what steps I have to follow to make my dongle as an hci usb and make it visible with the command hciconfig

RE: hciconfig is not showing my nrf52840 dongle on my linux terminal

Vidar Berg — Tue, 29 Jan 2019 07:31:50 GMT

nRF connect desktop uses serialized softdevice (Nordic BT stack) API to communicate with the connectivity chip, not HCI commands. In other words, ble_connectivity_s140_usb_hci_pca10059.hex will not work with the Bluez host.

Do you have a programmer to program the dongle, or do you need to upload the FW through USB DFU?
