code about gatts set value,is empty

[JonathanChenNew]

HI
I once posted a topic about gatts write attr value:viewtopic.php?f=2&t=1437
The function "esp_ble_gatts_set_attr_value" doesn't work.
Then i find that the code about "gatts write attr value" is empty in btc_gatts.c line 534.

So have ESP32 teams finished the work yet?
And when?

as a ble client,the function is "void btc_gattc_cb_handler(btc_msg_t *msg)".
but in my case , it is a ble server,and the function is "void btc_gatts_call_handler(btc_msg_t *msg)"
