But if you clear codes it resets all the readiness flags and the car has to go through one or more drive cycles before it marks them as ready, while others are marked ready right away (I think)
We were just shopping for a used car for my stepdaughter and many of the cars did not have all the readiness flags set, probably because of dead batteries and jump starts...
Search for drive cycle on this forum, there is a description somewhere, and that may help you get them all set.
Are you getting any DTC or just the readiness flags not set.
Btw I am using a $10 elm.bluetooth dongle, yours should be ok.
