Did anyone try to connect their DTA S-series via a RS232 bluetooth device ?  
I’m trying but without luck.

I can connect via an USB cable and it works fine, but when I connect the blutooth device on the ECU RS232 cable I dont get any data. I see the Bluetooth device in the “garage” setup.

My guess would be that RS232 Bluetooth device’s baud rate is not configured properly. This is typically done with terminal an AT commands. Refer to your adapter documentation on how to configure it.
