我读the source code of DA14580 Smart Dice firmware code. In accel_task.c, I figure out it deals with the write and notification operation for accelerometer profile. But I did not find read operation request handler? Could someone help me to locate that or I miss understand the structure of source code?

Hi Anson,
Do you mean the hander that is triggerred when a peer device is trying to read the value of the accelerometer?
Yes, I mean that. Can you specific this function?
安森,
Unfortunaltely there is not such a handler at this moment. That means the read will be noticed on a GATT server device. The best approach at this moment is to regularly update the value in characteristics.
