sending CTE at different frequencies

[Maen_Hanna]

Hey, 

I am trying to calculate distance between 2 BLE devices with nrf5340 by myself. i would have an initiator and a reflector. so my question is how can i configure my device as a reflector and how can i send CTE at different frequencies?

Thanke you

Hi

Okay, so what you describe is basically Bluetooth channel sounding, which will not be supported on the nRF5340 I'm afraid, so we will not be able to provide any support for this, and you'll unfortunately be on your own if you want to implement something like this on an nRF5340.

Best regards,

Simon

Hi,

Yes, I don't want any information about the Bluetooth channel Sounding. I only want to know how to send CTE on different carrier frequencies. I can see the channel index of the received CTE packet. I plot the I/Q data. The number of samples is 45, so my question is, does this mean that I can send a CTE request and get a CTE response from my TX with 45 I/Q samples? I am using the connectionless direct finding example.  How can I define my device as a reflector?
