The console auto-detects three styles, line by line. Any subset of fields works.

JSON — {"roll":2.1,"pitch":-5,"yaw":143,"ax":0.01,"ay":0.0,"az":1.0,"heading":143,"temp":22.4,"hum":41,"pres":1012.8,"gas":52000,"lat":44.47,"lon":-73.21,"alt":61,"sats":9}

key=value — roll=2.1 pitch=-5 yaw=143 ax=0.01 ay=0 az=1 temp=22.4 hum=41 pres=1012.8 gas=52000

CSV — send a header line once, then rows:
roll,pitch,yaw,ax,ay,az,heading,temp,hum,pres,gas,lat,lon,alt,sats

Aliases recognized: orientation via qw,qx,qy,qz quaternion, euler roll/pitch/yaw, or raw gx,gy,gz (integrated). Heading falls back to yaw or atan2(my,mx). Accel keys ax/accelX/acc_x, etc.
