Linker error with bluetooth sketches using bluefruit

[amoghprahar]

Hello,

I'm trying to get bluetooth development with Adafruit bluefruit libraries going on my nRF52840 board.

Environment:

• SparkFun Pro nRF52840 Mini
• 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-nrf52-feather-learning-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.

@amoghprahar, your topic has been moved to a more suitable location on the forum.

Oi tudo bem ?

Eu sou Brasileiro e estou passando pelo mesmo problema que você. Vi alguns tutoriais em alguns blogs aqui no Brasil, porém ainda não tive sucesso.

Estou Com o Bluetooth Nina - 302.

Vou fazer mais tentativas e vamos nos atualizando. Lamento não poder ajudar, mas infelizmente o que nós estamos trabalhando tem pouco material.

@luis_godoy, please post in English; google translate can help if needed.

Hey, how's it going ?

I'm Brazilian and I'm going through the same problem as you. I saw some tutorials on some blogs here in Brazil, but I still haven't had success.

I'm With Bluetooth Nina - 302.

I'll make more attempts and let's update ourselves. Sorry I can't help, but unfortunately what we're working on has very little material.
