Topdon carpal is not a bad scanner, it does a lot more than classic ELM327 but it’s not a bi-directional scanner.
You have to pay a subscription yearly (first year free) of $30/year, which is not a lot but if you pay a subscription of $50-60 you can get a scanner with a lot more features.
For example one of Bluetooth Bi-Directional scanners.
