About this app

The nRF Mesh Sniffer app is a powerful tool designed to provide developers and enthusiasts with the ability to capture and analyze Bluetooth mesh traffic over the ADV bearer. With this app, you can gain deep insights into the communication between devices in a Bluetooth mesh network.

With the nRF Mesh Sniffer app, you can perform real-time monitoring of the Bluetooth mesh traffic, making it easier to troubleshoot and debug your mesh network. You can identify potential issues such as packet collisions, latency, or connectivity problems. The captured data can be analyzed to gain insights into the network behavior, helping you optimize performance and enhance the overall user experience.

Features:
- Scanning over ADV bearer (only),
- Parsing all message types from Bluetooth Mesh Profile 1.0.1,
- Experimental support for Bluetooth Mesh Protocol 1.1,
- Importing mesh network configuration from nRF Mesh apps, or other apps compatible with Bluetooth Mesh Configuration Database 1.0.1 format,
- Merging scan sessions captured on multiple devices,
- Exporting and importing sessions in a JSON format.

Note: This app does not scan messages sent over GATT bearer. Messages sent from a phone to a GATT Proxy node will not be captured. Messages retransmitted over ADV bearer will.

Ratings and reviews

The export is only raw data, not unencrypted contents shown in the app. That makes this fairly useless for capturing logs to do any sort of complex analysis as you can't use them outside the app. Only useful for very basic checks.

I cannot find a way how to properly import keys. Importing json exported from NRF Mesh ends with "Failed to import keys" message...

Well done
