I have cypress ble module that generates carrier with PRBS9 modulation and GFSK on 2408MHz.
As a receiver I use nrf52 Dongle and nrf52 DK board. In RSSI viewer I can see signal on 2408MHz on both boards but when I use Direct Test Mode on nrf52 DK board there is no signal.
Firmware on nrf52 DK is okay because I can use it in transmitter mode, I can see signal on spectrum analyzer and on the nrf52 Donle in RSSI viewer mode.
Why the Nrf52 DK board doesn't show me signal in DTM in receiver mode? Does not work in both single and sweep modes.
