I got my new ELM327 thingy today, downloaded the Multi-wotsit, installed it, got everything working - but it keeps throwing up a message that there is no port found.

The ports are there, the dongle is recognised (it's a bluetoth one) I set the speed up, followed all the destructions, it "sees" the dongle, but when I try to scan - nothing except the message

Anyone else come across this or have any tips or tricks please?
