Can't sniff data between connected devices

Hi Tetsuya,

If you run the sniffer on a DK it should work. I'm not sure why it doesn't work with the Adafruit module.
But you should also try to test sniffing a Nordic peripheral, just to check if there is any incompatibility with the BGM220.

Hi Hung Bui
Thanks for your kindly response.

Okay, you are hard to support other than Nordic's kits.
I will try some way.
Would you please support me if I will use Nordic's kits?

Hi Tetsuya,
I would suggest to try testing again using a Nordic's nRF52 Development Kit.
We haven't tested the firmware with the Adafruid module.

Also please try testing to scan the BLE connection between a Nordic peripheral and the phone.

Hi Hung Bui
Thanks for your kindly response.

I'm using this.
www.adafruit.com/.../2269

I have tried for your advice.
Use the latest firmware version 3.1.
Downgrade Python 3.9 to 3.7

But I can't get data after CONNECT_IND.
I selected an advertising device correctly on the interface toolbar.

The advertising device uses BGM220 of Silicon Labs.
The scanning device is Pixel 4.

If you need more information to solve this issue, let me know what you need, please.

Hi Tetsuya,

Could you let me know the device you used as the sniffer ? And more information about the central and peripheral in your testing ?

Which sniffer firmware did you use ? Please try using latest version on our website v3.1

Please note that to be able to follow a connection, you would need to select the advertiser you want to follow from the dropdown menu. It can't follow a connection without selecting the advertise first. Please have a look at the documentation.

Also please try Python 3.7 instead of Python 3.9
