RF Waveform for Long Distance

[user3344]

Posting this in hardware because it seems like the most appropriate...

We are conducting some localization experiments where we will be capturing advertising packets of an NRF58240 that is in long distance mode, using a USRP.  In order to do so, we need to figure out the what the waveform of the packet looks like on the wire, and the data coming through.  Long distance mode has additional bits for FEC correct?  Are their tools out there that can give me what the actual waveform will look like (its DPSK?).  In order to make this simpler, we know what the advertising packet data is.  So I guess my question is, any ideas of where to begin?

Thanks

Hi,

 

Coded-PHY still uses GFSK like 'normal' BLE, the same PHY as 1 Mbps, just every 1 is coded as 1100 on air and every 0 is coded as 0011 on air.

 

Best regards,

Andreas
