do you want to test this wrapper ? a B4R project is added to show how to use.
More info about ELM327 interface and functions available with this wrapper are in cpp file of arduino library
2 modifications are added with B4R interface :
- acces to last data provided by ODB is done by GetPayload and in an Arraybyte created with length of Payload at init
- acces to ResponseBytes from ODB is done by GetResponseBytes in an Arraybyte of 8 bytes
13 Protocols for ELM configuration ares available in B4R
decoding of errors in status variable is available in B4R
i will have an EDM interface with wifi in a few week and i will test it at this time, but before you can check
