Characteristics read

[annapalu]

Hi all, is there a way to set a characteristics when a read command arrive from APP, or it's necessary to set it before to read?

I see for example battery service, it update the battery level with a timer clock and when you read, you read the past value if timer haven't expires, yet. If i want read the value of battery when a read request is made, what it is the correct method? I also think to use a notification, but i prefer use the read.

Thanks, Anna

Yes. It is possible if you use authorization. See this MSC for more information. There should be some questions in here about how to implement this.
