BLE 4.2 sniffer

lbehhhh

I am hoping to get solid verification that nordic offers a solution for sniffing BLE 4.2 packets.

The application I need to sniff is maxing out the MTU (250B payload) so I need support for long packets.

The blogs and googling haven't provided me with a solid answer.

Thanks

    At this moment our answer is no, we do not have plans to add this support. However it may change in the coming months.

    You were very clear. The links you posted said that the softdevice (recent) support packets longer than 23 bytes in BLE applications and that the old sniffer software is reasonably compatible with the nRF52832. Nowhere does it even hint that the longer packet capability in the softdevice extends to the sniffer, and it doesn't so I cannot draw the conclusion you have in 1) from those threads. I suspect the sniffer was an offshoot of the then-current softdevice code and as much as I'd love Nordic to continue developing it because it's an awesome resource, it doesn't feel like it's getting to the top of the priority list. And with the amount of work they've done recently introducing two new chips, modern BLE support and a very revamped SDK I'm not that surprised.

    I don't know of a long-packet sniffer, even less so a free one.
