Passing Out-of-Band key to Peer Manager?

Yes. Both LESC and Legacy end up with 128-bit encryption keys, and these are equally secure. The power consumption will be the same after pairing is done. LESC uses a more complex algorithm so it will use more power during the pairing process. The difference is in the key generation algorithm. It depends on what kind of attacks you want to protect against. If you do OOB with legacy and you are sure that the attacker can't get the OOB data, you are secure. If the attacker can get this data, you should go for LESC. What kind of central device are you connecting to? Does it support OOB and/or LESC?

edit: Now that I look it over again, is the difference between those two just the strength of the key generation algorithm? I assume the tradeoff between the two pairing methods is strength of security vs. power consumption, so since I want my connections to be bulletproof, I want to use LESC.

Do you want LESC pairing or Legacy pairing?
