pc-ble-driver-py example of writing a characteristic.

Question

I'm using the pc-ble-driver-py: Standard Heart Rate example to read a characteristic just fine. 
 My issue is i now need to write a to a characteristic. 
 How would I do that given the example above that reads great but can hypothetically write to the same characteristic read?

I figured it out. It's pretty simple, something like this for a custom service: (unverified after sanitizing) 
 self.ourBaseUUID = BLEUUIDBase([0x5e, 0x0a, 0xc3, 0x95, 0x70, 0xb0, 0xab, 0xae, 0xfd, 0x23, 0x6b, 0x79, 0x4a, 0x9b, 0x58, 0xda], 2) # base UUID type=2 (why?) self.ourCharUUID = BLEUUID(0x2001, self.ourBaseUUID) byte_array = [1, 2, 3, 4] self.adapter.write_req(conn_handle, self.ourCharUUID, byte_array)
