[nagendrapilladi]

I tried as per your suggestions but i got error 

pc_ble_driver_py.exceptions.NordicSemiException: CCCD not found

I defined as 

ACtual 128 bit UUID is : 

0x80, 0x82, 0xca, 0xa8, 0x41, 0xa6, 0x40, 0x21, 0x91, 0xc6, 0x56, 0xf9, 0xb9, 0x54, 0xcc, 0x34]

SUOTA_MEMD_UUID = BLEUUIDBase(
    [0x80, 0x82, 0x00, 0x00, 0x41, 0xa6, 0x40, 0x21, 0x91, 0xc6, 0x56, 0xf9, 0xb9, 0x54, 0xcc, 0x34])
NUS_SUOTA_MEMD_UUID = BLEUUID(0xcaa8, SUOTA_MEMD_UUID)



and added as 

self.adapter.driver.ble_vs_uuid_add(SUOTA_MEMD_UUID) in open function

self.adapter.enable_notification(conn_handle = new_conn, uuid = NUS_SUOTA_MEMD_UUID) 

in

def connect_and_discover(self)




i got error CCCD not found  This char is only Read and write attributes only


please support how to read and write operations on ACtual 128 bit UUID  .
