getVoltage() gets "stuck" and returns same value over and over
Stanley, I am using the OBD2UARTv1. My code detects when it can no longer communicate with the vehicle and then puts the ELM/STM chip to sleep using the built in lowpowermode function. Once that completes, I then leavelowpowermode and request the voltage using obd.getVoltage(). Then repeat the loop....

Re: Freematics OBDII is unable to upload.
I don't believe you are able to update or access the firmware in that model at all. In the past, I have used a secondary chip (Arduino in my case), hooked it up via a UART connection, and then programmed the Arduino to communicate with the OBD chipset. That is my experience with both the OBD2UARTv1 ...

New Function For Requests With Headers (Custom PIDs)
I created a new function in the OBD2UART.cpp file. Stanley, can you verify that my format is correct? I believe it needs to be 'header' # 'dataMode' 'pid'. The intention is then to be able to request custom manufacturer-specific PIDs that require a header. Do you believe this will function as desire...

Best way to use checkErrorMessage
Good morning, I am rather novice at C++, but purchased the UART adaptor and have it working very well on my vehicle. While testing, I noted that some PID requests were incrementing the obd.errors variable (which is totally fine). I wanted to determine what the error was so that I could programmatica...
