how many keys are needed for it to work?

I used a single key obtained from openhaystack, but it seems that it stops working after a while (may be 1 hour later) - is there a minimum number of keys to be set in keys.h?

(besides, i can't understand what is that 'toggle key derivation' option in OH, and where do you normally those 100 keys from?)

My key generation algorithm is pretty simple, but private, so I can't help with that. Did you adjust the key count in keys.h?

argh! my bad! it should probably read uint16_t advertisement_key_count = 1, not 100
thank you!

For anyone seeing this you can just generate keys with
