Hi All,
I've just been trying out the project from @Mark Hughes , uploaded here, using a HC12 to transmit GPS locations.
I’m using a set up whereby I have one Arduino, GPS Shield and HC12, attempting to transmit to a HC12 connected to another Arduino. When using the GPS Shield in standalone mode, over Port Monitor I can see it successfully creating NMEA sentences with all the GPS locations on. Also, when I just get the HC12s to communicate (as per this project), that works fine. As soon as I try and upload Mark's code to the Arduino to send the GPS over the HC12, it seems to error. What I see in Port Monitor for the GPS is just maybe a line and a half of GPS sentences (not pre-fixed by the string "Local GPS" as the script should create), and then the PM goes blank. Nothing is received on the remote HC12. I've attached a screenshot of the local GPS Port Monitor.
Does anyone have any ideas as to how I could debug this?
My current set up:
Both Arduino's powered by external 10V DC adapter (although the same result occurs when boards are just powered by USB)
One 220 uF capacitor resistor on HC12
Any help or advice greatly appreciated!
Cheers,
Seb
