nRF Sniffer using Wireshark, BLE logs

[Pranesh]

Device Name : nRF52840-DK PCA10056 

I have 4 questions listed below, the reason is Instead of creating multiple ticket/case we can follow up using the same ticket to avoid unnecessary confusion.

1) What is the best method to sniff BLE packets using DK ?

2) I've tried collecting logs using Wireshark but I could not see advertising name parameter why ?

3) I've tried collecting logs using Wireshark but I could not see ATT transaction why (or) Wireshark has capability to capture ATT Protocol ?

4) Can we capture logs using Frontline FTS tool or Ellisys tool? 

Thanks & Regards,

Hi Pranesh,

1) What is the best method to sniff BLE packets using DK ?

If you want to use the DK as the sniffer HW, then the only option is the nRF Sniffer. This is often good enough, but not the same as a professional sniffer (such as an Ellisys or Frontline device).

2) I've tried collecting logs using Wireshark but I could not see advertising name parameter why ?

Including the name in the advertising packet is optional. As this is missing here, it is probably either part of the scan response packet, or that the name is not advertised at all.

3) I've tried collecting logs using Wireshark but I could not see ATT transaction why (or) Wireshark has capability to capture ATT Protocol ?

Yes, ATT packets are supported by Wireshark. See Inspecting captured data. It does not give you the same level of presentation as you get from professional tools though.

4) Can we capture logs using Frontline FTS tool or Ellisys tool? 

Then you will need to use their HW. For instance Ellisys Bluetooth Explorer is an excellent sniffer.

Br,
