Sniffer using nRF52840

[Jinesh]

Hi,

I have nRF52840 dongle PCA10059. I want to use dongle as sniffer.

So how and what hex file and other thing i need to do ? To use dongle work as sniffer.

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.

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.

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 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.

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.
