btchip_verifyPin requires 8 character hexadecimal PIN

[aussiehash]

The minimum PIN length in decimal is 4 characters, however btchip_verifyPin rejects any PIN shorter than 4 hexadecimal characters

Okay, I've figured it out, the documentation is pretty unclear for this

The minimum PIN length is 4 characters, you need a to convert that PIN into Hexadecimal Alt Codes

0 = 30 
1 = 31
2 = 32
3 = 33
4 = 34
5 = 35
6 = 36
7 = 37
8 = 38
9 = 39

The btchip_verifyPin command seems to break connectivity on OSX, requiring a powercycle (which then requires another btchip_verifyPin to prevent 6982 error
