Plugin that tests what version of elm327 you're using

[aha999]

Problem:

Currently there may be some issues and confusion among users, because the ELM327 market is very wide and the products differ, use different firmware versions and users may experience incompatibility of their adapters with the functions they're expecting or don't even know if those functions are supported or there is an issue somewhere else if the desired functions don't work. Often time the issue can be in the adapter because the sellers often declare a wrong ELM327 compatibility.
There exist a handful of apps that serve this purpose, but they are all proprietary.

Solution:

I propose, that an AndrOBD plugin is developed, which could test the connected adapter for listed protocols/standards/functions and display how many of those are supported. Since AndrOBD is open source, the proprietary issue could be avoided and a FOSS option could finally be available.

Examples with screenshots of proprietary apps that have this feature:

• first app,
• second app

Additional context:

I think that there is no need for this to be a separate app, because AndrOBD already has a lot of functionality and such a plugin could help in getting more users. Also, when testing the adapters, screenshot of this plugin could be posted at the product sites (as currently are with some non-foss apps), which could get AndrOBD more users.
