Constant Tone Extension

I have nrf52833 as Tx. Ialso have nrf52833+ antenna array as Rx. I want to send CTE data, implement IQ sampling and view AOA for implementing direction finding. Kindly assist with some reference code that i can test.

Hi!

Great, then you have everything you need.

I'd suggest you try the "direction finding connectionless" examples we have available in NCS v1.6. You can find them in the projects drop-down menu in SES, or at nrf/samples/bluetooth. For more info take a look at its documentation.

Best regards,

I have run this example i.e connection less transmitter on nr52833 tx. But not getting how IQ sampling is enable on the code so that i can obtain AOA on my receiver side. How will i be able to view and analyse the angle data received ??

[Elfving]

If you want something readymade to view the angles, then yeah I can imagine this isn't helping :/ 

Didn't you get an AoA solution from Insight SiP to work with their antenna?

hello, i have received Insight Sip kit. I am able to connect the antenna to the PC and inserted battery to ble beacon by insight. But when i am connceting the antenna to direction viewer app i am unable to see the angles?

Hey!

That's weird. I am a bit unfamiliar with the Insight software package, I'll look into it and get back to you about this once I know more. 

In the meantime, can you see if IQ data is being recieved in the terminal?
