aci_gatt_update_char_value returns undocumented error code

Associate III

Modified the BLE_Throughput example to use indication characteristics instead of the notification.

I also set the interval to 1 second for debugging purposes because I saw that only 1 IND is read by the client per connection interval.

I see that SendData function is called frequently.

The characteristics is only sent 1/s to the client.

The aci_gatt_update_char_value returns 0x0C.

What is this error code?

How could I push more "messages" to the IND characteristic?

Do I understand the BLE spec correct that IND requires at least 1 connection interval of "round trip" to be ACKed therefore 1 IND/interval is allowed?

0x0C means already updated?
