Isn't ```go func (c DeviceCharacteristic) Write(p []byte) (n int, err error) { c.service.device.prph.WriteCharacteristic(p, c.characteristic, true) return len(p), nil } ``` in `gattc_darwin.go` all that is needed ?

Yes, these are two separate concepts: `write` === `write request` `write without response` === `write command` `gate_windows.go` indeed already has `write` capability I've tested the code with changes I mentioned...
