nRF Sniffer not working

[Mayank Gupta]

Nordic Team,

We are using Bluefruit LE Sniffer - Bluetooth Low Energy (BLE 4.0) - nRF51822 - v3.0 to sniff packets from BLE 4.0 device - but we are finding it hard to connect the nRF Sniffer application with Sniffer hardware. The slide switch in at DAT mode on the hardware.

Please find the Log files attached.

Looking forward from some pointers as to what we are doing wrong.

Hi Mayank,

I would suggest you to also send the question to Adafruit.

Did you flash new firmware to the sniffer or it was the firmware came with the sniffer ? Adafruit may have their own firmware for the sniffer.

Have you check if a new COM port is opened on the PC ?

Hi Hung Bui,

Thanks for your revert.

I have put up the same on their forum, but still waiting for somebody to reply. Yes they have a firmware but I am not aware if the board is pre-programmed or I have to program it.

Yes the USB gets detected everytime. I tried to use the Python API provided by Adafruit to do some debugging and noticed that the port gets opened but software receives no reply for PING_REQUEST.

I am not sure if i received a broken module or if something has changed in the way things work. The content at Adafruit is not up-to-date and somehow I cannot confirm the same for nRF-Sniff as well.

If you have their hex file, and if you can program the board, I would suggest to test if the UART working properly by flashing a UART test program. You would need to match the pin to the UART pin used on the board.

I have their hex file, but i don't have programming cable. Also, they recommend not to re-program. I have returned the item.

Hi Mayank,

Any advance with the issue ?

I have same dongle from Adafruit and same trouble. "ble-sniffer.exe" does not get to see bluefruit. It remains searching for the device. I've confirmed that new COM port is opened when plug the dongle.

Any help will be appreciated.

Regards,

Asier.
