I solved this problem by using nrf_ble_qwr.c.

But I got a new question.

When writing less than 20 bytes, the length can be confirmed below.

· p_evt_write-> len

How do you check the length when it is longwrite?

There is no thing as a long read, the central will have to read the characteristic piece by piece by using an offset, see GATTC Characteristic or Descriptor Value Read.

The Queued Writes module in SDK v15.0.0 implements queued writes, a.k.a long writes.

We have a nRF5 SDK v15.0.0: Experimental: Queued Writes Application that shows how the QWR module is intended to be used.

Best regards
