Hi,
I would like to use PCA10031 to be a sniffer. It can't update and show as below figure.
I've also refer to discussion as below website to turn it into BOOTLOADER mode and then copy-paste the newly version of J-Link OB-SAM3U128-V2-NordicSemi 170724.bin into PCA10031.

The LD1 keep blinking after firmware update. Is it correct?
