Use p2pkit with cordova! iOS and Android supported. Currently limited to enabling and discovery due to my limited available time and scope when starting this, but everything else should be fairly easy to add. PRs and bug reports welcome!
Installing:
cordova plugin add cordova-plugin-p2pkit --variable BLUETOOTH_USAGE_DESCRIPTION="your usage message" --save
Functions:
cordova.plugins.p2pkit.isP2PServicesAvailable(success, error) - Android only
cordova.plugins.p2pkit.enableP2PKit(apikey, success, error)
cordova.plugins.p2pkit.createP2pDiscoveryListener(opts)
Here, opts is an object with callback functions, include the ones you need:
{
onP2PStateChanged: function(data){},
onPeerDiscovered: function(data){},
onPeerLost: function(data){},
onPeerUpdatedDiscoveryInfo: function(data){},
onProximityStrengthChanged: function(data){}
}
the data parameters in onPeer* functions and onProximityStrengthChanged have a peer field with uuid and proximityStrength fields, and onP2PStateChanged has a state field which is the returned state id (These are different in android and ios!) and they correspond to the values described here: Android iOS.
