Hello.

How can i change GATT charProperties of added GATT characteristics?

Is that possible?

I need to remove Read/WriteProperties (CHAR_PROP_READ/WRITE) of all characteristics when GATT service will be locked.

It`s a requirement of Eddystone protocol.

Thanks.

P.S. I tried to delete GATT characteristic with aci_gatt_del_char() function (i tried to delete char and create it with other Properties) and it returns 0xFF status (BLE_STATUS_TIMEOUT).

Is aci_gatt_del_char() function supported by BlueNRG v6.4. firmware?

I had the same troubles with hci_le_set_advertising_data() API function.  In firmware v6.3. it works correctly. But in v6.4. it returns

BLE_STATUS_TIMEOUT (0xFF).
