Hi, all.

I am trying to get the indication of SERVICE_CHANGED characteristic in GATT.
But I have not succeeded yet.

As described in RW-BLE-GATT-IS.pdf, I have tried to send GATTC_SVC_CHANGED_IND_CMD message to TASK_GATTC from TASK_APP with parameters below.

req_type -> GATTC_SVC_CHANGED or GATTC_INDICATE.
svc_shdl and svc_ehdl -> The range of all characteristic handles I use.

Of course, I enabled CCC descriptor of SERVICE_CHANGED characteristic from client Android application.

Did I correctly send a indication?
Are there any other conditions to perform indication?
