Is it possible to flash NRF52DK with Arduino Code using BLEPeripheral Library?

[Michael]

Hi, I purchased a Sparkfun Breakout board for the NRF52832, but the bootloader on it seems to be extremely unstable. Hence, I've decided to flash the NRF52832 directly from the NRF52DK itself, and then remove the NRF52832 to be used on an external PCB board. I've tried BLE OTA (over the air) and experienced many problems, I've tried PlatformIO and experienced some compatibility issues. I've also tried changing the .bin (output from arduino after hitting compile) to a .hex -> then uploading as an application + softdevice through NRF GO, but this doesn't work for some reason. Please let me know of a solution to this if you're aware of one. Thank you very much in advance.

The question title indicate that you are trying to flash the nRF52-DK, but the description indicate that you try to flash external board using nRF52DK, which is it? If second, how have you connected the board? You should describe your issues in more details than saying: "I tried, but I experienced problems/it did not work".
