First, check the pin-out of the connector to make sure you are getting 12 from the battery on pin 16 and ground on 4 and 5.
Open this to learn the pin-out locations:

If you are not getting 12v from #16, try ignition on or even with the engine running. No power means the dongle that connects to Torque won’t work. Check for a bad fuse.
Seems like the Bluetooth dongle that works with Easydiag should work with Torque Pro. Maybe you don’t have the Torque set to receive from the Bluetooth devices you own. I have 3 ELM 327 compatible dongles and all work with Torque.
