Can the nRF52832 capture packets without address matching?

[rfpenguin]

Hi, I would like to capture all bluetooth packets on a specific channel, and get their access code. Same as what Ubertooth does. Is it possible using the nRF52832? If not perhaps another IC?

Thanks.

Hi,

If you are looking for a sniffer tool, please take a look at our nRF sniffer. See this link.

Not, I'm looking into building a generic sniffer that capture all traffic from a single channel, regardless of the access address.

Q: Can the nRF52832 capture packets without address matching?

A: No.

How this works in BLE, is that all BLE advertising packets are sent using the same (access) address, 0x8E89BED6. When a connection request packet is sent from the BLE master to the advertising device, in order to establish a connection, a part of the CONNECT_REQ packet includes the new address the devices should use in the connection.
