[PATCH BlueZ v3 0/5] core: gatt: Support enabling notifications

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



*v3: Removed Change-Id lines from patch descriptions.

*v2: Cancel ongoing CCC writes in bt_gatt_client_free.

*v1: Make bt_gatt_register_notify cancellable via bt_gatt_unregister_notify.
     notify_client_free now unregisters its notify id, which will cancel any
     pending CCC write, as well as unregister a registered notify callback.

This patch sets brings support for enabling notifications while in GATT
client-role. The changes that are introduced are:

  1. Implemented the StartNotify and StopNotify methods of the
     GattCharacteristic1 interface. This are internally tied to
     bt_gatt_client_register_notify and bt_gatt_client_unregister_notify.
     These also manage notification sessions on a per dbus sender basis.

  2. The exported GATT API objects are not removed in the event of a disconnect,
     if the devices are bonded. All notification sessions are also persisted and
     automatically re-enabled on reconnection. Also, adding new notification
     sessions via StartNotify is allowed during disconnects.

  shared/gatt: Make register_notify cancellable
  core: gatt: Implement GattCharacteristic1.StartNotify
  core: gatt: Implement GattCharacteristic1.StopNotify
  core: device: Don't check ready in service_removed
  core: gatt: Keep objects over disconnects
