LE whilte list problem

[hanf gai]

Hi, i'm trying to connect multi LE peripherals using gap_whiltelist_* method, but it alwaysconnect just one peripheral.l tryed change MAX_NR_HCI_CONNECTIONS,but not works.

I can connect multi peripheral directly using gap_connect function.

My HCl Host Platform is Ubuntu 20.04 ((Program modifed from PoSlX).HCl Controller isnRF52832 with Zephyr HCl firmware (you can find codehere zephyr/samples/bluetooth/hciuart at main ·zephyrproject-rtos/zephyr (github.com))they communicate over UART with flow control.

What should l do to position this problem?

Can you help me? Tell me what info you wanna know. Thanks of al!!

Hi Hanf Gai

If you use gap_connect_with_whitelist, it only connects to the first device. if you want to connect to more/additional devices, you need to remove the device that was connected and call gap_connect_with_whitelist again.
If something doesn't work as expected, please also send the packet log, on Linux in /tmp/hci_dump.pklg for a quick analysis.

Cheers
Matthias

Hi  Matthias :

    I confirmed my code that I called `gap_whitelist_remove` when the connection was established.

    There is btstack loggings below, and  I noticed that when I called `gap_whitelist_app` a second time,  btstack did not receive any events.

    I upload both txt log and bin log at there:

Hi Hanf

I was only able to download text file and converted it to .pklg.
In that log, there's a event

Command Status - LE Create Connection - ACL Connection Already Exists

I'm not sure why it reports this. Could you try to share a full .pklg file (you can zip it if needed) from startup?

Best
Matthias

Hi Matthias:

    I upload log again in Dropbox, you can download here (https://www.dropbox.com/scl/fi/x2616re0tiofx6e0hcf65/log.zip?rlkey=wu6coo8alizyqcd22w6rr9phg&dl=0)

[Matthias Ringwald]

Hi Hanf

Thanks for the full log. From a first look, it seems like a bug in the Zephyr Controller. Can you test their latest version?
If this remains, I would suggest to post an issue in the Zephyr Issue tracker. If you do, please also post a link here.

Cheers
Matthias

Hi Matthias:

    Think you for your information; I tried the latest release version(v3.6.0-rc3) for zephyr, the issus was exists.

    I make a discussion in here BluetoothLE HCI RAW H4 Question · zephyrproject-rtos/zephyr · Discussion #69922 (github.com)
