Subject: [PATCH BlueZ v2 0/2] Optionally require security for notify/indicate
Date: Wed, 29 Sep 2021 14:00:29 -0400 [thread overview]
Message-ID: <20210929180031.417090-1-dmartinez@starry.com> (raw)
In some cases, it is desirable to require encryption and/or
authentication for server-initiated updates, as they may contain
sensitive data.
Currently, there is no way to do this with BlueZ.
Here is a query about this feature from 2019:
https://stackoverflow.com/questions/55884233
This patch implements this feature by introducing new `x-asynchronous`
flags that allow a user to restrict access to a characteristic's CCCD
(as well as documentation for those flags).
