Is there a way to configure the nRF5340 RADIO peripheral to receive a packet with any address (i.e. promiscuous mode)?

[Kevin Doss]

Typically the Base address registers and Prefix registers are used to configure up to 8 logical addresses and then RXADDRESSES is used to filter which of the 8 logical address you wish to filter a received packet with. In a proprietary application, can you configure the radio to receive any address and decide in software whether to accept it or not?

Hi, 

Unfortunately, it cannot achieve as the requirement.

Thank you for your answer. I know that the nRF51 and nRF52 DKs support the nRF Bluetooth sniffer application (https://www.nordicsemi.com/Products/Development-tools/nRF-Sniffer-for-Bluetooth-LE). Does this imply that those devices DO support promiscuous mode receive (i.e. accept any address)?

No. It needs to be known beforehand. For e.g. BLE advertising. all advertising packets use access address 0x8e89bed6 i.e. you configure the access address you want to send/receive on beforehand. But maybe that sniffer is just scanning through all the access address possible for a BLE connection. i.e. access address number 1: wait x milliseconds for a match, then next address, wait x milliseconds for the match, then it goes through all addresses possible, looking for packets.
