Is ELM327 version 1.5 supported?

[pacmandu]

Hey I got a adapter for a Bluetooth connection to an ELM327. However, even with the engine running I am unable to query details from the car itself. The car is a 2014 Scion FRS and the adapter is powered correctly because I was able to get the firmware version. What am I doing wrong here? Do I need to set the protocol manually? The car is idling at about 800-1000 RPM at the time of this output.

Output from my test code:

Here is when I set manually protocol 5.

Sorry one more dump. Turns out it is receiving data but it can't parse it. I have confirmed that is is pulling the RPMs and Speed properly but the library can't parse multiple responses in the same line as shown below:

Confirmed the Speed is 0 and RPMs are around 682. What gives about the library for saying the Vehicle did not return any acceptable messages when in fact it did?
