How do reserve the received packets, and write them on a file (like, txt) in the flash, then how to extract the file from the flash onto my computer?https://devzone.nordicsemi.com/f/nordic-q-a/79669/how-do-reserve-the-received-packets-and-write-them-on-a-file-like-txt-in-the-flash-then-how-to-extract-the-file-from-the-flash-onto-my-computerHi There, I try to send some packets from a file between two devices. Now, I want to confirm and analyse whether I receive the total packets correctly or not. Two points: 1. Write the packet on a file in the flash. 2.

If you are using a terminal window (e.g. tera term), then you can simply output the data to UART, and on the PC use the terminal window to view or store the UART data to a log file on a PC.</p> <p>Kenneth</p><div style="clear:both;"></div>
