Hello,
I am not sure what I am doing wrong? This did work at one time.
I have an Arduino that is outputting through Bluetooth. (Verified output)
I have also uploaded my XML file to RealDash as well.
I am fairly new to RealDash and Arduino, but I have a great head start on this project.
I would upload my XML file, but I cannot because I an new to foum.
Thanks in advance.
Things to check:
Hello realdashdev,
Thank you for the response. I have made some progress.
I used the Can Monitor to verify that I am receiving information from the Arduino (through Bluetooth) to Real Dash. I did not have this before when I made the post, so now I at least have information being received in a readable format by RealDash.
I was not aware of the Debug Data View. This is very helpful! Thank you for this.
I am getting some values, but they are not the right values. The Serial Print on the Arduino is producing the right values, but the translation is lost to Real Dash; this makes me believe that the XML is wrong.
Actually I think I figured it out, but it is probably not pretty… and definitely not optimized!

Would appreciate any feedback on this though!
Looks good to me :thumbs:
