Regarding Direction finding in BLE 5.1

[William i.w lim]

I have some question about direction finding in BLE5.1.

1. Does the 52840 DK support nRF52811 Soc? if not, Is there any Development kit support nRF52811?

2. Does the AOA Implementation in mobile need to be upgraded new mobile h/w(chip) and s/w( next version of oreo in case android)?

3. what is minimum requirement to implement AOD in mobile ?

    Only OS upgrade can make AOD possible? if not, we need install new h/w in mobile compliant to BLE 5.1?

I found 52840 DK support nRF52811 but, do not support direction finding function in BLE 5.1. Thanx. AndreasF

Hi.

Correct, no direction finding features in nRF52840, you can read that here.

Hello,

How could someone prepare FW for the actual nRF52811? Looking at http://developer.nordicsemi.com/nRF5_SDK/nRF5_SDK_v15.x.x/doc/15.3.0/release_notes.txt and further "Supported boards" ( https://www.nordicsemi.com/DocLib/Content/SDK_Doc/nRF5_SDK/v15-3-0/sdk_for_custom_boards ) there is no mention of nRF52811 chip whatsoever, only pca10056e emulated on nRF52840 DK. What woldd be starting point for such project configuration - pca10040 or pca10056e? I assume that the first one?

[AndreasF]

Hi.

If you want to emulate nRF52811 on a nRF52840 DK, you have to use the project configuration found in the pca10056e folders.

In SDK 15.3 these are already set up:

Hello Andreas,

Thank you for your reply. My thinking was to prepare the firmware for actual nRF52811 chip more than to work on the emulated version. What would be different in such case?

[AndreasF]

Hi again.

You should only have to do as listed on the Infocenter, take a look at that :-)

Best regards,

Andreas

Thank you, I've missed the "Transferring the project to nRF52811 hardware" section :)
