flashing hex files through UART

[roger.k]

Hi. I'm using PCA10028, SDK10.0.0, S130. I'm a beginner. If I want to download hex files(soft device and fw code) though UART port, is it possible? If possible, could you give me a tip or example code? I hope your reply.

Yes. It is possible. Main difference to boot-loader is firmware file is transferred UART not OTA. You should refer uart/bootloader example and compose packet that can detect transmission error.(UART doesn't ensure end-to-end reliable transmission). Regards.
