Questions about how to view BLE raw data

[pkr2258]

hi

I am configuring a product using nRF52832 and NUS.

This time, I'm trying to view BLE wireless data (raw) from central and peripheral, ​​but I can't find a way to do it, so I'm asking.

1) The peripheral's advertising data was confirmed in the nRF Connect APP as shown below.

2) This time, I want to see the central response data (raw) for the above advertising, but I can't find a way.

3) After pairing, I would like to see the raw data and packet structure of data communication. Are there any related methods and materials?

thank.

Hi, 

You can use nRF Sniffer for Bluetooth LE, see Setting up nRF Sniffer for Bluetooth LE - Nordic Developer Academy (nordicsemi.com)

hi

I have already tried using sniffer and wireshark in conjunction.

however,

1) The channel settings are only 37, 38, and 39 advertising channels.

I can't set up zoom to the data communication channel. Is that really the case?

Is there a way to zoom in and view the data communication channel?

2) Too much data appears, making it difficult to find.

Is it possible to filter the parts I need? BLE Name, etc.

3) Is there any data on the data packet structure of the NUS response and request of SDK 17.1.0 that I am using?

thank
