I didn't update the latest library, just follow the steps to change the program.

Hi!

First thanks for pointing out the bug but now I have another problem.

I am running zephyr/samples/bluetooth/ direction_finding_connectionless_rx sample appplication with minor modifications. I had no problem building application. Then I updated my local zephyr project repository (to get rid of mentioned bug). Now my appliaction won't build beacuse of some Kconfig warning.

Here is the complete console output from Eclipse IDE:

I have tried with fresh sample with no modifications and I got the same error.

Do you have any clue what is going on?

Hi,

Excuse me, AOA Tag TX. After the direction_finding_connectionless_ tx program is written on the NRF52833DK development board, the log print program runs normally. NRF Connect can't search for this device.

thanks

I'm glad to hear from you. The problem has been solved. Thank you

Hello yangwen!

Thank you for being interested in direction finding.

I'd like to answer to your question about channel index in bt_df_per_adv_sync_iq_samples_report structure. Unfortunately there was a bug in the upstream code. The channel index was wrong.

I've created an issue to track it in Zephyr GitHub: https://github.com/zephyrproject-rtos/zephyr/issues/36022.

I've also created a bug-fix.

Here is a PR: https://github.com/zephyrproject-rtos/zephyr/pull/36023 that solves the problem.

You can wait for merge of the PR into upstream.

Best regards,

Piotr

The value of chan_idx in the bt_df_per_adv_sync_iq_samples_report structure of the zephyr routine is not 0x00-0x27. How to convert the value to the corresponding frequency.For example, what is the frequency of 0x6c.Thank you！

No we dont, i belive it's described in the white paper how this should be done..

Best regards,

Do you have a dome that converts IQ into an angle, or provides relevant information.Thank you

We've solved it

Why do I use zephyr's "direction"_ finding_ connectionless_ tx”，“direction_ finding_ connectionless_ rx "can not receive the signal of TX, TX output information is successful. Using nRF_Connect, only when TX is powered on, it can be scanned once

Hi,

for information about our roadmap for direction finding support, please contact your local Nordic Regional Sales Manager.

You can have a look at this example from Zephyr that uses the nRF52833DK, as well as our whitepaper on direction finding.

Best regards,

Kaja
