Implementation of BT Pairing via NFC Handover
46 bytes, text/x-github-pull-request

Details | Review
The user can initiate BT pairing via NFC. The most common use case is with BT enabled speakers or headsets. 1) The user can tap an NFC enabled BT device (e.g. BT speakers, BT headsets etc) to allow easy pairing with that BT device. No typical BT interactions (choosing a device to pair, entering pin codes) are necessary. a) The above can happen at any point/screen on the mobile (as long as NFC is turned on). b) If BT is turned off, the user will be prompted to turn on BT. c) If music is already playing on the mobile, tapping on a NFC enabled BT speaker/headset to initiate a BT connection will lead to pairing, connecting the BT device and then transferring the music playback to the speaker/headset.

Hi, do we have a clear view on the target milestone on this bug now? Thanks.
It seems better to finish this bug before sprint5. If you think it isn't reasonable, please update target milestone.
Target Milestone: --- → 1.3 Sprint 5 - 11/22
Garner, I wonder if you would fix this bug in NFC manager.
Assignee: alive → dgarnerlee
I believe Arno just finished the static pairing, so I'll assign to him.

Depends on: 933113
This is the first patch for handling a static handover via NFC. This patch basically contains a whole bunch of NDEF parsing functions to pull out the Bluetooth MAC address of the device to be paired with. Note that NFC Manager requires some changes to call functions in this patch. Garner is currently giving the NFC manager a serious facelift and I will add the patches for NFC manager once he is done. This code was successfully used to pair a Motorola Boom Bluetooth headset with a FFOS device.

Comment on attachment 831799 [details] [diff] [review] 0001-Bug-903305-Utility-functions-for-handover-handling.patch Review of attachment 831799 [details] [diff] [review]: ----------------------------------------------------------------- The flow isn't clear to me. So here is my understanding: Someone(NFC manager?) will call HandoverManager.pair() and pass a ndef message. The message will be parsed by NdefHandoverCodec and other utility functions, then finally get a bluetooth mac address for pairing. If BT has already on, do pair immediately, otherwise, turn on BT and add a callback. If I'm correct, then I think your BT part isn't doing the thing as I described. You shouldn't call |InitHandoverManager| while the script is loaded, because there is nothing we can do until getting a BT address. Regarding your utility object and functions , like NdefUtils, NdefConsts, Buffer, NdefCodec, and NdefHandoverCodec, please wrap into one or two object(s) with some private objects and functions.

My apologies, Evelyn. Our master was not current which is why there were so many strange commits. My bad. This pull request should be fine now. Please note that this pull request contains two commits: I squashed our entire NFC code base in one commit (parts of which are currently under review) and one commit that only contains the handover code I would like you to review. This should make it easier for you to identify my changes.

Comment on attachment 8334904 [details] [review] Fix for reviewers comments Despite my comments on Github, I have some overall comments and questions: 1. mixing patterns: I see at least 3 ways to define classes and 2 ways to protect a function to be private. I think you might have some reasons so I'd like hear them. In Gaia, we usually choose either module pattern(for protect method as private) or object with prototype functions. The biggest concern in your code is that memory consumption because every instance will keep a copy of functions which are the same. Why not use prototype? On the other hand, your private functions usually access HandoverManager's properties via `self.xxx`, so why not define these properties private (e.g., var DEBUG), too? 2. Some functions are actually do the same or similar things. Especially those in xxxUtils objects. Bad smell here. 3. Why we don't parse ndef message in Gecko? Please also checkout my rest comments on Github.

Attached file Restructuring and fixes (obsolete) —
Thanks for your feedback. This version tries to address your concerns and it also adds support for a sendFile() API (untested since required BT API is not yet available). The lazy loading of the .js file is not done and will be fixed together with the loading of nfc_manager.js. For other remarks I will respond inline in your comment.

OK, you are right that NFC Manager has similar utility functions. The cleanest way would be to add a file nfc_util.js and put all common code there. The NFC Manager is under review by Alive and since you guys don't like patches changing apart from your change requests, I opted for this solution. Can you and Alive please discuss and decide how you would like to handle this? > Okay.. then please add the bug number in comment, like: '//XXX: gecko bug > xxxxxx' BT is also a fast moving train. That particular issue has been fixed and the hard coded MAC address will be removed from the next patch. > I'm reviewing the patch, more feedback are coming. I also want to test this > patch if I can get one device with NFC. Please note that the only thing working right now is BT pairing. You need to hold a BT device (such as NFC-enabled headset) to the device and it will be paired. None of the file sharing functionality can be tested because of 915533 but Eric said they are working hard on landing this.

Comment on attachment 8336479 [details] [review] Restructuring and fixes feedback+ I think there is no big problem in this patch, only a nits and clean up need to be addressed: 1. please move HandoverManager.prototype.handleHandover* prototype declaration out from HandoverManager declaration. Defining prototype inside HandoverManager will also create a function copy and overwrite prototype object in every instance, is it what you want? 2. we can exclude "NFC code base" commit now, I'm totally understanding the whole flow. Thanks for making this for my reference. 3. as I suggest in my comment 30, move the whole file sharing code to another new bug. Let this patch only do things matched bug title - BT pairing.

Alive has r+ bug 860910, and I feel like it's not a big problem that I want to argue here. A follow-up bug to move these common utilities to nfc.util is good to me.

Defining prototype inside > HandoverManager will also create a function copy and overwrite prototype > object in every instance, is it what you want? So, when I move the prototype declaration outside of HandoverManager, I no longer have access to private members/functions of HandoverManager due to JavaScript scoping rules (e.g., call debug(), doAction() etc from within handleHandoverSelect()). Note that HandoverManager will only ever be instantiated once (at the end of the file where the singleton is stored in 'handoverManager'), so technically the prototype would not even be required here. If you still want this to be a prototype, I would have to expose more private API. Please let me know your preference. > 2. we can exclude "NFC code base" commit now, I'm totally understanding the > whole flow. Thanks for making this for my reference.

I don't have a headset that support NFC on hand, so I use a Nexus4 and do some hacks to make pair process moving on. (my hacks: fake ndefMsg with handover_select type, and hard-code BT mac to be paired) So the patch works as expected except a pairing confirmation pops-up. Per spec, I guess we will do silent pairing here, but since gecko BT stack has no idea the defaultAdapter.pair() is from NFC, so the pair flow goes as usual: send "bluetooth-pairing-request" to Settings app to display a confirmation screen. It looks like we need some tricks to bypass this UI. Please file a follow-up bug. The patch is still failed on travis, I've re-run it many times. running now: https://travis-ci.org/mozilla-b2g/gaia/builds/14736065
