James, This sounds weird. PINs were only used in classic Bluetooth as far as I know and have since been replaced with SSP. I don't think iOS can do classic Bluetooth so I would expect your are being requested to enter an SSP passcode exposed by a peer device in BTLE. In that case a 6-digit number between "000000" and "999999" is generated (same is true for classic actually). By the BT standard, all six digits must be present. The iOS (or somebody) must be bending the rules because a three-digit entry should fail. At least that is my understanding.
