[quote user="damienking"]i mean RX receiver sensitivity.[/quote]

The DTM sample will provide a RX sensitivity result but that would be done with lab equipment like an Anritsu.

https://infocenter.nordicsemi.com/pdf/nwp_006.pdf?cp=17_20 here is a white paper that does show a way to do it.

Hi,

I think you want to look in the the Radio test Example, it might fit better you rest goals.

[quote user=""]is it ok to set nRF52840's Tx power to this range -127~+20dBm?[/quote]

The nRF52840 does not output +20dBm, max is +8dBm.
TX power list here: https://infocenter.nordicsemi.com/topic/ps_nrf52840/radio.html?cp=4_0_0_5_19_13_46#register.TXPOWER

[quote user=""]and how to read the receiver Rx power by The UART command?[/quote]

Do you mean RX receiver sensitivity?
