Re: [Teep] Hardware for hackathons

[Akira Tsukamoto <[e-mail]>]

Hi,

I forgot to include about the CBOR parser.
I personally prefer to using CBOR parser at the next hackathon.

Isobe-san,
Do you mind looping Takita-san who had his CBOR parser at the
hackathon some time ago?
(BTW, should I be start using the first name instead of last name?)
