Script-Player Handy Over Bluetooth Firmware 3. Much better expirience

For me, WiFi still handles the complex scripts better then BT… IS there a way i can get the same with BT?

Like the vibration on some scripts are just stutters on BT

Most likely not. When you control the Handy via wifi you download the entire script to the device and only timestamps are communicated from time to time to make sure the script remains in sync. With BT every stroke is sent as a command and that is way more data and is pushing the BT communication to the limits of the specification for fast scripts.
