nRF52840 Sense not BLEing Moderators: adafruit_support_bill, adafruit

I just hooked up my Feather nRF52840 Sense board. All seems to be working, except BLE. Just including bluefruit.h and trying Bluefruit.begin() results in this compiler error, among others:

Code: Select all | TOGGLE FULL SIZE

I'm using Arduino 1.8.13 on a Raspberry Pi4. Any ideas?

Have you updated the board file and the libraries? Check this out and see if it is any help. Try the examples included, to check the programming, and if it does not work still post your code. Thanks.

Yes, I have have been thru the tutorials and tried many revisions and re-installs. The Pi clearly doesn't have something that nRFCrypto requires (something that provides SaSiLib for example) . It's not my code; I'm simply trying to compile this:

#include  <bluefruit.h>

void setup()
{
  Bluefruit.begin();
}

void loop()
{
  // doesn't matter
}

Confirmed that things are working nicely on a Windows box. How about a little love for us Raspberry Pi Guys?

I'll update this thread if I stumble upon something.

Talk to the folks over at the Arduino forums:

http://forum.arduino.cc/

They're the ones who build and maintain the IDE.

It's an Open Source project, so you're welcome to get involved and contribute to any parts you think need improvement.

[douglaso]

I understand. There's no problem with the IDE. The problem begins in Adafruit software:

Code: Select all | TOGGLE FULL SIZE

/home/pi/Arduino/libraries/Adafruit_nRFCrypto/src/Adafruit_nRFCrypto.cpp:71: undefined reference to `SaSi_LibInit'

At least, I assumed you would try to maintain code with your company name on it.

the libraries are def supported - but we haven't ever used arduino on raspi, so if you're using the exact same setup on both windows and raspi and it doesnt work on raspi ... we wouldn't know why htats happening.
make sure you've got the latest IDE, libraries, and all that. the library code we've got should work the same on both! :)

[douglaso]

Thank you. I was hoping it might just be some cryptography piece that is not distributed with Linux (or Debian, or whatever) for international reasons. May still be. My C is lacking, but if I find anything out, I'll update this post. In general, the Pi makes a very fine AVR etc development workstation.

[adafruit2]

the maintainer is currently on break but will be back in a few days and will check it out when they return :)

I just setup my Pi4 and run a compile test, it seems to compile just fine. I use arduino-cli though, since I mostly use Pi4 as headless.

1. What is your Pi OS , I am testing with 32-bit version.
2. Could you provide the uname -a output on your PI4,

it looks like the arduino ide has issue with Adafruit_nRFCrypto library linking with lib file and source (mixed). Would you mind upgrading your Arduino IDE and try again, probably with at least 1.8.15. If the issue still exists, please attached the full compile log here for analysis.

[douglaso]

Thank you very much hathach! Reinstalling the IDE with 1.8.19 (from .13) seems to have none the trick. No problems now. So I guess it was the IDE after all. I shoulda knowed. You guys at Adafruit never let one down.

[hathach]

I am glad that works for you. Happy hacking
