Hello, I was successful in using Arduino headers/ libraries to program my nRF52 DK, but now I am attempting to recreate the project in Segger V5.34 for MacOS for potential mass production. I am using the ble_app_template example from the nRF52 SDK 17.0.2 and I am following this tutorial. (The only deviation was that I named the variables differently) I was on Step 4 before issues arrived. However, when I build and run everything, nothing is advertised. I also wanted to add that I am new to Segger, but I understand C pretty well. I have already flashed the S132 SoftDevice (At least, I'm pretty sure) This nRF52 DK was advertising perfectly fine when I used Arduino, so the board works. There just seems to be an issue with my code or configurations, because when I hit 'Build and Run' the board is on but nothing happens. It's also worth mentioning that the PWM examples work perfectly fine. Thank you for all the examples, by the way. They're very helpful. Thanks in advance!
