Just a quick word... Fixed packet lengths... !!
The variable lengths between the ESP and Teensy are using '<' & '>' as start and end, but the float data especially, is including a bracket, mid-packet and dropping the packet out early..
I'd given up on odo and fuel because of the packet corruption, but I've just changed it all to a fixed 26 byte length and now it's sweet... Really smooth, compared to the odd spikes I was getting..
Started to add a 1.5" Oled for speed fuel and Odo, and altho I ran out of time, it's looking good...
Luv Chrisie.. xx
