nRF52840 Dongle firmware

[emmovo]

I've made a dongle using the nrf52840, and I'd like this custom device to work with the RSSI Viewer and Bluetooth Low Energy on nRF Connect for desktop; what do I need to do to achieve this? Do I need to write a specific firmware to my device so that RSSI Viewer and Bluetooth Low Energy can recognise my device? Is there any development material available for the nRF52840 Dongle?

Hi,

Firmware for the RSSI viewer is publicly released with the pc-nrfconnect-rssi project on github. You will find precompiled hex files as well as the source file. You may have to port the code and build your own hex files, depending on the differences between your board and the boards already supported.

The nRF Connect for Desktop Bluetooth Low Energy app has been using a modified version of SoftDevice serialization, with patch files for the SDK (and precompiled hex files) publicly released as part of the pc-ble-driver project on github. Please note that this is not future proof, since new features will not be added to the now-in-maintenance-mode nRF5 SDK and SoftDevice.

In general we do not recommend building any new projects on nRF5 SDK. Even though the firmware we delivered for certain nRF Connect for Desktop apps were developed using the nRF5 SDK, this is not a future-proof solution. For new projects, we recommend nRF Connect SDK. However I do see that for backwards compatibility with existing tools, there may be situations where one would want to use nRF5 SDK based solutions, such as in this case with porting old firmware to a new board.

For more information on choice of SDK, please see our nRF Connect SDK and nRF5 SDK statement.
