SparkFun Pro nRF52840 Mini - Bluetooth problems

Development Boards Arduino
1

Hello,

I’m trying to get bluetooth development going on my SparkFun Pro nRF52840 Mini.

Environment:

  • Mac Book Pro 13" - Mac OS X 10.14.6

  • Arduino 1.8.13

I followed the Arduino BSP installation instructions at https://github.com/adafruit/Adafruit_nRF52_Arduino. Because I hit the problem described in the last FAQ of https://learn.adafruit.com/bluefruit-nr … guide/faqs (i.e., “Unable to upload sketch/update bootloader with macOS”), I followed the instructions and built and copied over the self-contained adafruit-nrfutil as described in https://github.com/adafruit/Adafruit_nRF52_nrfutil

At this point, I can make simple sketches (like blinking LED) to work on the board.

However, when I try to build a simple bluetooth example sketch (like blinky_ota), the Arduino IDE gives the following error:

Arduino: 1.8.13 Hourly Build 2020/04/21 12:12 (Mac OS X), Board: "SparkFun Pro nRF52840 Mini, s140 6.1.1 r0, Level 0 (Release)"

Error compiling for board SparkFun Pro nRF52840 Mini.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

I have confirmed that the Adafruit_nRFCrypto library is indeed installed in a sibling directory to Bluefruit52Lib, and I can include the header file. However, it doesn’t seem to be getting linked in. I have even tried explicitly installing Adafruit_nRFCrypto and Arduino notices the duplicate installation but the same error exists.

I’d appreciate any help to fix this problem.

Try adding the nrf Crypto library https://platformio.org/lib/show/8257/Ad … 0nRFCrypto and see if that does anything

Unfortunately, I’ve tried that and it doesn’t work.

As I mentioned in my initial message, if I explicitly install and import Adafruit_nRFCryoto, the Arduino IDE recognizes that the library has duplicate installation but still gives the linker error.

It might be time to try wiping everything and starting over, ensuring you have 1 version installed and are using the SparkFun board packages, as you follow our hookup guide here https://learn.sparkfun.com/tutorials/nr … cuitpython
