Hello All,
The question is about the Minimal Weather Sensor from Sean's store : what is the procedure to calibrate the offsets for the barometer and temperature sensor (BMP280).
The setup is as follows : the minimal weather sensor is pluged to USB on a linux box (openplotter) and identified as /dev/ttyUSB0 (cat /dev/ttyUSB0 shows the expected NMEA0183 output).
It seems from looking at the arduino code (https://github.com/pypilot/pypilot/blob/...ensors.ino) that sending "\r" character (carriage return) to /dev/ttyUSB0 is expected to lead to a configuration over serial but this seems to fail when I try (using the echo command or minicom).
Would someone have a hint on the subject ?
Best regards,
Xavier.
