Unable to capture any data messages "DATA PDU", although able to capture advertisement and connect request PDU via nrf52 ble sniffer

[Subhanshu Sahu]

I have configured "nrf 52 DK" to worked as BLE sniffer. I am trying to sniff the data packets exchanged between two TI CC 2650 devices (in which one is master and other is slave).

I am only able to view the captured packets of "ADV_IND" and "CONNECT_REQ" PDU and not able to view any data messages between slave and master. Although the slave device is keeping sending a message after every 0.5 second.

Can someone guide how I can capture the data packets?

Thanks in advance!

Try to remove the "37" in Adv Hop "37". 

Also, do you know whether the link is encrypted earlier? If so, you need to delete the bonding information before you start sniffing. If you use any OOB keys, you must also enter them in the "Passkey / OOB key" field in Wireshark.

The "Device" field, is the one that you have set it to the peripheral or the central?

Best regards,

Hey Edvin, can you please provide me latest hex file for setting up nrf 52 DK as ble sniffer?

You must use a hex file that is intended for the version of the sniffer that you use. What version of the nRF Sniffer do you use? You can find a link to download the sniffer, which includes the hex file here.
