The CTE (Constant Tone Extension) feature can be used on the DTM (Direct Test Mode) with the nRF5 SDK v16.0.0 (latest version) now?

[wasicat]

I want to trying to the HCI Command (DTM Mode) of CTE (Constant Tone Extension) feature for SIG RF Pre-TEST, 

The nRF5 SDK v16.0.0 (latest version) is ready for CTE feature now (with nRF52833)?

And..I see the nRF52833 is only one antenna connector, How to use for multi antenna (AoA/ AoD)

Thanks

Hi,

 

SDK v16.0.0 has support for nRF52833 but does not support the direction finding test cases.

 

To use multiple antennas you need to use RF switches to switch between multiple antennas. These are controlled using GPIOs as described in the PS.

 

Best regards,

Andreas

Thanks for your reply,

On the product page, I see the nRF52833 can support the direction finding feature, What time can support the direction finding test cases (DTM mode)? Have any plan or schedule to support this feature?

Hi,

 

The HW supports direction finding, but this is quite complex stuff and entirely new to us, so unfortunately getting the Software to a state where it is making your development more easy compared to starting from scratch is taking some time. I do not have a schedule unfortunately, you should contact the Nordic Regional Sales Manager who is handling your region for this an possible other roadmap related questions. PM me if you need contact info.

 

Best regards,

Andreas
