nRF51822 seems to not work after flashing #10

Open KlausMu opened 1 week ago

KlausMu commented 1 week ago

I went through the README to flash a nRF51822. To my understanding, everything worked as expected. But after flashing, I can't see the tag, neither in "Android nRF Connect", nor can the tag being added to "Find My" in an iPhone.

The tag is from AliExpress (HolyIoT) and looks like this: image image image

The command for flashing was

make stflash-nrf51822_xxac-patched ADV_KEYS_FILE=/home/klaus/projects/airtag/heystack-nrf5x/tools/output-nrf51822-2/nrf51822-2_keyfile ADVERTISING_INTERVAL=2000 KEY_ROTATION_INTERVAL=3600*12 MAX_KEYS=50 HAS_DEBUG=1

Log while flashing was:

I'll take a look, It seems https://github.com/pix/heystack-nrf5x/issues/7 has the same problem. I have these tags on a previous firmware version.
