1. Under tools\include\profiles\BlueLab-7.0.3-Release, write .dbi and .h
2、

4. Add #include "gatt_example_server_db.dbi" in sink_gatt_db.db;
5. Just compile, and sink_gatt_db.c and sink_gatt_db.h will be generated.
6. When connecting, it will access the interface display information such as CCC, the protocol stack report event GATT_MANAGER_SERVER_ACCESS_IND will enter sinkGattManagerMsgHandler, the native code general GATT is not processed here, as shown in the figure below, it needs to be modified to: gatt_status_success
Modify it as follows, and add the GATT ind function handleMGattAccessInd at the same time, as shown below:
Then implement the interface, and implement the write and read interfaces at the same time, as shown in the figure below:
7. The interface for GATT to send data is:
