I want to use 52832 to measure the frequency offset and Modulation Characteristics in the advertising packet sent by Bluetooth slave.

I want to use 52832 to measure the frequency offset and Modulation Characteristics in the advertising packet sent by Bluetooth slave.How can I do it?
I think this information is brought by the receiver when it demodulates the signal.

Hi Sun,

you will not be able to use the nRF52832's RADIO alone to measure the frequency offsett and mod. characteristics.

Can you explain why not？Do you have some better ways？I just want to use Bluetooth module to make a simple testing tool.

I dont see how you are able to determine the phase offset from the RX frequency of an incoming RF signal, let alone determine the amplitude, phase, pulse sequence, and pulse duration by using the information in the RADIO Registers.
