Pairing

[zdennis]

Is it possible to force pairing with bleno (and to subsequently pair successfully)?

And... awesome project. Used it today to test out a firmware change for some hardware and it saved me a ton of time and frustration.

Sweet, thanks!

Which OS are you running bleno on? At this time secure reads/writes for characteristics are not supported. To add support for OS X is not too bad, however Linux is more work, but it would be nice if both are supported at the same time.

I'm running bleno on a RaspberryPi. I had to manually install node 0.10.23, but after that everything else installed fairly easily.

If there are any docs for secure reads/writes on OSX and/or Linux that you know of I'd love to be pointed in a direction. But if not no worries, I can always work on my google-fu. Thanks again @sandeepmistry for bleno!

I'll take another look at this on Linux on the weekend.

For OS X, you would need to add the appropriate masks:

    CBAttributePermissionsReadEncryptionRequired    = 0x04,
    CBAttributePermissionsWriteEncryptionRequired   = 0x08

to the permission here.

Linux is a bit trickier since bleno has a built in ATT/GATT stack, you'd have to track down how BlueZ sets the socket security level (here's a good place to start).

@zdennis I've added initial secure support in these commits: a94018d...19c9106. You'll have to try out the version from master until I publish a new version to npm.

Linux appears to be working well, however OS X has some issues at the OS/blued level (I couldn't get secure read/write/notify going via Objective-C + CoreBluetooth, but the same code works on iOS).

Thanks @sandeepmistry ! I've been away on holiday, but am back now. I will check this out.

With regard to getting secure read/write/notify with ObjectiveC. Are you talking about having the peripheral be on OSX or with regard to having an OSX central be able to successfully pair/bond with a linux-based peripheral that had secure set on read/write/notify?

[sandeepmistry]

Things are working on Linux as both a central (via noble) and a peripheral (via bleno).

On OS X the central has no issues with secure read/write/notify with security of medium. However, I couldn't get OS X 10.9 to work with security in peripheral mode. If you be great if you could try that out.
