Nordic SDK with Adafruit Feather nRF52 Bluefruit LE - nRF52832

[JPat]

Hello,

I am using the Adafruit Feather nRF52 Bluefruit LE - nRF52832 for a project where I will have to transmit and receive data over Bluetooth Low Energy between two of these devices. I would like to use the Nordic SDK for this instead of Arduino.

I am using Segger Embedded Studio for programming and I have a J-Link base.

How would I go about flashing this device with an example (ble_app_blinky) from the Nordic SDK (version 17.1)?

Additionally, right now the Adafruit Feather boards have their default bootloader. I am assuming I will have to change this. How should I go about doing this?

Thank you for your help.

You’ll need to solder a SWD header to the pads immediately below the nrf module and use a jlink to program the nrf52.

For new development I recommend to look at the nRF Connect SDK (NCS), all new features will be occuring on the NCS platform. The nRF5 SDK is in maintenance mode, so looking into future I recommend the nRF Connect SDK for new development.

To get started I recommend to check out nRF Connect SDK introduction video:
https://webinars.nordicsemi.com/introducing-nrf-connect-for-vs-code-5 
(Installation video: https://www.youtube.com/playlist?list=PLx_tBuQ_KSqEt7NK-H7Lu78lT2OijwIMl)

I can see Adafruit is supported in NCS:

For development I recommend getting a jlinnk to program the nRF52, for instance you can order an nRF52-DK, which can support on-board and off-board programming over the SWD interface. Refer to the user guide for the nRF52-DK.

Best regards,
