  Yes, yes, it is indeed this issue.

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

  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.

  I plan to learn the source code when I have some free time in a while and try to solve this problem (since I don't have a hardware background myself, I actually find it a bit difficult, though you say it's easy).

  There are indeed some issues with ESP32, sad...

  After solving the existing problems, I found that callback function for onWrite() is not implemented.
  And Unable to implement the notify and indicate, my phone always reports error when sending notification listening requests to ESP32.

  NRF.setServices({
    0x1901: {
      0x1902: {
        value : "Hello",
        broadcast : true,
        readable : true,
        writable : true,
        notify : true,
        indicate: true,
        onWrite: (event) => {
          console.log("Got: ", event);
        }
      }
    }
  });
