In next line, you can see the list of sensors that should be discovered
List of ibus fields : 0 11 12 15 16 17 23 1 0 5 2 3 4
Forget the first 0 in the list (it has no meaning)
Then here the meaning of the codes (some are not transmitted on Ibus):
0 = LATITUDE =0, // GPS special format
1 = LONGITUDE, // GPS special format
2= GROUNDSPEED , // GPS cm/s
3= HEADING, // GPS 0.01 degree
4= ALTITUDE , // GPS cm

5= NUMSAT , // 5 GPS no unit
6= GPS_DATE , // GPS special format AAMMJJFF
7= GPS_TIME , // GPS special format HHMMSS00
8= GPS_PDOP , // GPS no unit
9= GPS_HOME_BEARING, // GPS degree

10= GPS_HOME_DISTANCE, // 10 GPS in m
11= MVOLT, // volt1 in mVolt
12= CURRENT, // volt2 must be in seq for voltage.cpp in mA (mV)
13= RESERVE1, // volt3 must be in seq for voltage.cpp in mV
14= RESERVE2, // volt4 must be in seq for voltage.cpp in mV

15= CAPACITY, // based on current (volt2) in mAh
16= TEMP1, // = Volt3 but saved as temp in degree
17= TEMP2, // = Volt4 but saved as temp in degree
17= VSPEED, // baro in cm/s
19= RELATIVEALT , // baro in cm

20= PITCH, // 20 imu in degree
21= ROLL, // imu in degree
22= YAW , // not used to save data in degree
23= RPM , // RPM sensor in Herzt
