ESB RSSI on ACK

[DamonKelly]

Is it possible to get the RSSI on the ACK coming from the PRX back to the PTX?

To clarify -- I mean the "empty" ACK with no special payload.

Looks to me like RADIO_SHORTS_ADDRESS_RSSISTART_Msk is already enabled, so it should in theory be to read NRF_RADIO->RSSISAMPLE on NRF_ESB_EVENT_TX_SUCCESS in nrf_esb_event_handler().

Kenneth, that seems to work.

Are there any particular details to be aware of (timing, etc...), or is that all taken care of by the ESB driver and Radio HW?
