BLE advertising starts only after the RTT Viewer successfully connects.

[mento]

I originally developed the product using the nRF5 SDK with C++. The functionality is already implemented, but due to high power consumption from the C++ version, I now plan to use NCS + Zephyr and develop in C.

Currently, I am encountering an issue: BLE advertising only starts after the RTT Viewer connects. I have tried disabling the RTT functionality, but BLE advertising still requires the RTT Viewer to connect before it starts.

I have also changed it to a non-blocking configuration, but the issue persists. Please assist me in resolving this problem. Thank you

Hello,

You are not writing anything about your nRF52832 hardware here, but normally the projects are setup to use the DCDC circuitry and external 32kHz for lowest power, if you have not mounted the DCDC circuitry or added external 32kHz then it won't start up.

Please check debugging tips in this thread (same applies for the nRF52832):  nRF52840-DK only executing while debugging
