nRF Sniffer for Bluetooth LE hardware requirements. Can you run the precompiled HEX files on something other than Nordic Development Kits?

Hi,

I am currently using a nRF52-DK as a nRF Sniffer for Bluetooth LE. However I would like to use some other hardware instead which allows for the permanent attachment of an external antenna as the nRF52-DK isn't very well setup for that. Hence, I'd like to program the precompiled Sniffer HEX file onto a generic nRF52 module that has an external antenna connection.

How can I best achieve this? I imagine I will need to hook up a UART->USB to a particular set of pins on the nRF52 chip? Are you able to share which pins those are? Is there anything else to note?

Thanks.

Hi,

We do not support running the sniffer firmware on other/custom boards. That said, it is sometimes possible as long as the board includes the 32.768 kHz crystal and DCDC indutors. If those components are not present, it will not work.

Regarding which pins to use for UART, you can refer to the hardware files for the DK you use firmware for, and see which pins are used on that DK. For the nRF52 DK, the UART GPIO pins are Rx:8, Tx6, CTS:7, RTC:5.
