Adafruit Feather NRf52840 Zigbee with NRF connect SDK

by ErikNL on Sun Jan 23, 2022 3:11 pm

I recently bought A Adafruit Feather NRf52840.
Since the NRf52840 supports Zigbee, I was hoping to use the board to experiment a bit with Zigbee.
The Arduino libraries don't seem to include a Zigbee API, but the Nordic semiconductor NRF connect SDK does, and it also includes a lot of samples.

I was wondering if I can use the NRF connect SDK with the Adafruit Feather NRf52840. I have installed the toolchain and VS code, but at "connected devices" the board does not show up. I also tried the official Nordic semiconductor programmer, but when I select the board there, it shows:

Code: Select all | TOGGLE FULL SIZE
Unsupported device. The detected device could not be recognized as neither JLink device nor Nordic USB device.


I found some information here that is maybe related: https://docs.zephyrproject.org/2.6.0/bo ... index.html
There's some information there about needing a external programmer connected to the SWD header. Would that be the case for what I'm trying to do too?
Would I need something like this: https://www.adafruit.com/product/2209 (combined with https://www.adafruit.com/product/2094 and https://www.adafruit.com/product/1675) ?

yep you will need a jlink programmer or similar to load code onto the board. it has a bootloader but that bootloader is not a zephyr-type (its for arduino/circuitpython only). there used to be the more affordable jlink mini but during the silicon shortage they haven't been making them :( you may want to pick up a nordic devboard that has a built in programmer to get started. it'll also have the most support from the nrf sdk! (can alwyas then have it work on the feather after you've learned it)

Thanks for the clarification, a nordic devboard might indeed be a better starting point for now, since the jlink programmer is quite a investment.
