Sniffer using nRF52840

The fundamental is that the nRF52840 dongle is using USB peripheral to communicate with the PC when the sniffer firmware currently use UART peripheral to communicate with PC. Changing this would requires a firmware modification.

This dongle is made to be a small, compact, convenient sniffer. The software change to send data via USB instead of serial is small. Is there a fundamental reason why the software is not available for this dongle?

Please download the sniffer firmware&software here: https://www.nordicsemi.com/Software-and-tools/Development-Tools/nRF-Sniffer-for-Bluetooth-LE/Download#infotabs

The source code of the sniffer is not available but the hex file is included.

I strongly suggest to get hold of a nRF52 DK. It will save you a lot of time. We do have distributor in India that can provide the DKs.

Hi Hung Bui,

Thank for your input. I will make connection as you said. And will have UART to USB.
But can you please provide me the sniffer code file to be dumb in nRF.

Also I don't have much more nRF52 DK, so this is only the option is left for me.

You need to get pin P0.06 (TXD) and P0.08 (RXD) to connect to a RS232 driver before you connect to PC. I wouldn't suggest to go for that. It's better to get hold of a nRF52 DK (either nRF52832 or NRF52840)

Hi Hung Bui,
Thank for your quick reply.
So I understood, that if i will take out the any 2 pins from the dongle and configured as UART.
Then it can work as Sniffer.
If my understanding is true. Can you provide the link for the sniffer code to configured the DIO pin as UART.
And what further step i need to do to have a sniffer using UART.

Hi Jinesh,

Unfortunately our sniffer firmware doesn't support the USB interface on the PCA10059 yet. It currently only support the UART interface. Hope that we will have support for PCA10059 in 2020. A nRF52 DK is required for the sniffer.
