Adafruit Bluefruit LE Sniffer Nordic Plugin broken Link

[Cowboyfan2001]

I am trying to set up the nRF51822 Adafruit Bluefruit LE Sniffer. I first go to this link https://learn.adafruit.com/introducing-the-adafruit-bluefruit-le-sniffer/v2-wireshark-usage Under the "Install Wireshark Plugin" tab there is a green download button that says: "Download Latest nRF Sniffer Software Bundle", The button leads me to this page: https://www.nordicsemi.com/Software-and-Tools/Development-Tools/nRF-Sniffer/Download#infotabs which returns a 404 Error.

My Question is this, where can I go to find the plugin bundle, or the necessary files of the 51822 sniffer? The file needs to be installed into extcap directory.

I'm trying to identify the frequency of the signal as well as it's contents. The signal is transmitted from my smartphone to my Oticon Connect Clip and then to my hearing aids. That way I can emulate the expensive and easily misplaced Connectclip for a much cheaper solution.

Development Setup: Windows 10, Wireshark 3.2.3, nRF 51822 v2, Oticon ConnectClip, Huawei honor 8x, Oticon Opn hearing aids.

Hello,

The button leads me to this page: https://www.nordicsemi.com/Software-and-Tools/Development-Tools/nRF-Sniffer/Download#infotabs which returns a 404 Error.

This is an error with the adafruit website. I have sent them an email detailing the issue, and providing them with the correct link:

My Question is this, where can I go to find the plugin bundle, or the necessary files of the 51822 sniffer? The file needs to be installed into extcap directory.

If you follow the link I referenced above you will find the correct download page for the nRF Sniffer.
I suggest that you download the tool from there, and continue on with the Adafruit guide - since you are working with an Adafruit product.
Since the Adafruit BLE Sniffer is a Adafruit product, I have very limited knowledge about it.

I'm trying to identify the frequency of the signal as well as it's contents. The signal is transmitted from my smartphone to my Oticon Connect Clip and then to my hearing aids. That way I can emulate the expensive and easily misplaced Connectclip for a much cheaper solution.

I am unable to advice you on how to duplicate the product you mention, and I have not heard about this product in particular before, but if it is using BLE then the signal will be within the BLE frequency band.
Reconstructing the data format used from a selection of received packages might also prove a daunting task, but it might be possible to do from the packages you receive if you are able to connect to it, or if the manufacturer provide some API or other interface intended for programming. Another thing would be if it used an open source standard for the transmissions, which would make things a whole lot easier.
There might also be security features in place to prevent access to said data formats or to prevent device subversion. All in all there is a lot of uncertainties with the procedure you describe, but you are free to proceed with it.

Best regards,
Karl
