Now with Nano!
There is a new hex-file available for Arduino Nano of Nano is your preferred board. Connect the sensor’s VCC to Nano 3V3 pin and other to same as in Pro Mini and off you go. RCT Uploader work fine with Nano too. (Note that no resistor is used with Jeti VarioMeter)
Serial Speed Issues
Jeti has some inconsistency with serial speeds in the receivers. R-series are ok with one speed, REX’s EXT port is sometimes a bit tricky and require a bit different speed and REX’s E1 and E2 port differ a bit from EXT-port. Every now and then I need to make a special hex for a user so there is now extra hex-files available in a zip-file to test Pro Mini’s with depending your specific setup.
As usual, check the Jeti VarioMeter page!
