exFAT support on macOS seems to have some bugs because my external drives with exFAT formatting will randomly get corrupted.

Disk Utility is unable to repair this at first, but the fix is this:

1. Use diskutil list to find the right drive id.
2. You want the id under the IDENTIFIER column, it should look like disk1s1
3. Run sudo fsck_exfat -d <id from above>. eg sudo fsck_exfat -d disk1s3
4. -d is debug so you'll see all your files output as they're processed.
5. Answer YES if it gives you the prompt Main boot region needs to be updated. Yes/No?

Basic Manual for DaFit Fitness Tracker firmware update protocol, works for nearly any nRF52832 tracker from Company DaFit

The minimum size of update file is 0x10000(can be filled with garbage to get to size) and the maximum size is 0x2F000
the update will first get stored onto the external flash at position 0x3D1000 by the stock firmware(not by the bootloader)
the size of the update will get stored at 0x3D0000 on external flash with 4 bytes uint32_t

when bootloader gets activated it will copy the update from external flash to 0x23000 of the nRF52 internal flash.

$ docker run -v openvpn_data:/etc/openvpn --rm -it evolvedm/openvpn-rpi ovpn_initpki
