Updating is in real time while advertising. This is currently limited to
25 bytes and will return an error message of "Too much data" if that
maximum has been exceeded. However, this does not check if the advertis-
ing payload length maximum has been exceeded so you may receive an er-
ror from bluetoothd that it "Failed to register advertisement" which
means you need to reduce your manufacturer data length.
Usage > manufacturer [id] [data=xx xx ...]
data
Set/Get advertise data.
This allows you to advertise data with a given type. You cannot use a
registered data type value {1} with this command. For LE the advertis-
ing shows up in the primary advertisements.
If you set only the type of the data without any data (data 0x0c) this
will cause a parse error when turning advertise on.
You can modify the advertising data while it is advertising.

ments.

duration
Set/Get advertise duration.
The Duration parameter configures the length of an Instance.
The value is in seconds.
A value of 0 indicates a default value is chosen for the Duration.
The default is 2 seconds.
If only one advertising Instance has been added, then the Duration value
will be ignored.
If multiple advertising Instances have been added, then the Duration
value will be used to determine the length of time each Instance is ad-
vertised for.
The Duration value is used to calculate the number of advertising events
that will be used to advertise each Instance.
The number of advertising events is calculated by dividing the Duration
value by the advertising interval.
The advertising interval is determined by the advertising parameters
that are set for each Instance. The advertising interval is the maximum
of the advertising intervals set for each Instance.
Usage > duration [seconds]

The Interval value is used to calculate the number of advertising events
that will be used to advertise each Instance.
The number of advertising events is calculated by dividing the Duration
value by the advertising interval.
The advertising interval is determined by the advertising parameters
that are set for each Instance.
The advertising interval is the maximum of the advertising intervals set
for each Instance.
