Sniffing BLE 5.0 packets

[Ankit]

Hi,

I am aware of how to use nRF51 sniffer with wireshark.

But in my current project, I am not able to sniff data packets. I am not sure which BLE stack is used in the product. whether it is BLE 4.2 or BLE 5.0.

I am able to capture advertising packets. I am able to capture connection request. I am able to capture empty PDUs.

Is there any way that I can identify the stack version from advertising packets or connection request?

Can we sniff packets of BLE mesh network via nRF51 sniffer?

Hi Ankit,

Beside connection request and empty PDUs, what else can you capture ? Can you capture the Security encryption request ? Or PHY change request ? and Feature request ?

The feature request and response will reveal if 4.2 is supported or not.

Could you post a screenshot of a captured session ?

The nRF51 sniffer should be able to BLE mesh packets, as long as the Mesh use the default advertising access address 0x8E89BED6. But it was not made to parse them and follow a communication (SAR packets for example)
