no no no no no... writing does work!
just the callback function onWrite() is not implemented
I can both read and write / edit the value of certain characteristic, but could not call the onWrite() callback function
In my conception, I should write / edit the value of characteristic A, and then my ESP32 call the onWrite() callback function to verify this value. If the value is valid, ESP32 will change characteristic B to readable mode.
Just like some kind of encryption verification.

Yes that is good, what I meant is that if you don't get the callback then you don't know what value was written so writing is not very useful.

I can read it after writing, so I can read the value I wrote. Just write => read.
