Support Jade Connectivity via Bluetooth

[tadeubas]

Some users are reporting that Green: Bitcoin Wallet from Blockstream isn’t working with certain Jade DIY units, as described in issue #185. Some jade DIY boards fail to work over USB and also lack a camera, leaving Bluetooth as the only viable communication method.

Since Sparrow doesn’t support Bluetooth for Jade either, it would be great to have this functionality working in the Bitcoin Safe wallet 😉

I didn't even know there is a Jade DIY :-)

While it may be the only option to connect to iPhones, I'm not sure I can make the effort to support yet another (completely different) connection method, additional to QR,SD and USB.

Perhaps HWI is the correct place to add bluetooth support?

@tadeubas see Blockstream/green_ios#93 later. I managed to isolate the error and I have the solution. I'm waiting for the devs' position on whether or not to open a PR.

@tadeubas

I have a working branch andreasgriffin/bitcoin-usb#59 that supports jade bluetooth. With any luck I'll be able to bring this into Bitcoin Safe.
