I think the Bitcoin community needs a good person-to-person payment
protocol for BLE simply because Bluetooth LE is effectively
peer-to-peer. Unlike NFC or conventional Bluetooth, a $5 micro can
be either the master or slave and talk directly to other $5 micros
nearby.

Probably on Android it's being verified in Java instead of C++. Some

BLE meets a different use case than regular Bluetooth. BLE is designed to
allow always-on broadcast "beacons" which are conceptually similar to NFC
tags, with very low power requirements. The tradeoff for this ultra-low
power consumption and always on nature is the same as with NFC tags: you

Agree, range is not an issue. The trade-off is in battery vs. total
time, which would be influenced primarily by the battery sensitivity of
the platform. I'll send you a note to follow up.

Hello,
I personally would prefer as low of range as possible for this bluetooth
application considering the connection is not yet encrypted (mentioned
below), and even if it were, it seems like it is always going to be
better in case there is some vulnerability. From my testing with a

Hi Andy,
This is good stuff. I've spent quite a bit of time on this question, but
set aside most of it earlier in the year in order to make some progress
in other areas. I did review what I found available at the time
pertaining to the Schildbach implementation and these questions.
Skimming the li
Hello,
With the recent discussion started today regarding another bluetooth
communication proposal created by Airbitz, I'd like to bring people's
attention back to this proposal that saw little discussion last fall. I
guess I'm not sure why two proposals are being created. Is their some

Not at all, it should be very easy in Java because of how the SSL API is
designed. I'd worry more about non-Java platforms.
However, SSL

Hey Andy,

One thing this brings up is the never-resolved issue of whether BIPs should
document how we'd *like* things to work, or how things *actually do* work.
BIP32 is an example of the former - it was new technology and the spec was

Hello,
I'd like to introduce two proposed BIPs. They are primarily focused on
implementing the payment protocol using bluetooth connections. I've been
working on automated point of sale devices and bluetooth communication
