I'm trying to pair it with my phone. Don't have any other BT 'sending' devices atm. Here's what happened.
When first trying to pair, the Flare only showed up with a bluetooth icon and the truncated name 'Soundcore Flar'. When trying to pair with the device it would give me that error message about an incorrect PIN or passphrase. I cycled bluetooth and power on both devices. Same result. The third time around, after I had tried to pair and as the bluetooth button was flashing in pair mode, I pressed the bluetooth button with a second single, quick press. The device then showed up as 'Soundcore Flar' and also 'SoundCore Flare' and with a 'headset' icon. Trying to pair with this 'new' device worked fine.
Without another device to pair to I can't rule out the phone.
I do know that I own a pair of Liberty Lites, Soundcore Curve headphones, two Soundcore Mini 2s, a Soundcore 2, and some JBL Everest Elites. They all pair just fine with my phone.
As of now I can say that turning the Flare off and then back on, it automatically pairs with my phone so I shouldn't have any further problems.
I don't want to sound like I'm complaining, I really appreciate Anker doing this for us. I don't mean to 'look a gift-horse in the mouth', just trying to figure out how to get it to work. Thank you again Anker!
Listening to the Flare, I'm really digging it. Not just because it was free, but because it ROCKS! This is really a neat idea and I'm excited to take it to the discgolf course with me this week.
