There are many "at" commands that can be sent to an odb2 adapter. Here is a link to them for ELM327, https://www.sparkfun.com/datasheets/Widg...mmands.pdf.
The odb2 gauges allow sending at commands pre and post pid. A Query for voltage is to simply send "AT RV" to the odb2 adapter and expecting a data response. But it looks like that is not covered in the odb2 gauge/sensor configuration.
I have seen some discussion about reading voltage but no solutions other that more hardware. This "AT RV" seems simple enough. If you configured a pre-at command, no pid and no post-at command, just send the at command and expect data back.
It seems like there should be a way to do this. Daniel, can you confirm if this is possible or is there no mechanism in OA to do this?
