I'm having trouble to activate Maxbotix I2C sonar in this version.
It dose not even initialized (there is no sound from the sensor).
Works on 3.4.6.
I saw that in this branch (3.5) the rangefinder code is changed and there is no primary, just orientation.
Maybe it something to do with it?

The relevant parameters:
RNGFND_ADDR,0 (Relevant only for I2C Lightwere sensor)
RNGFND_FUNCTION,0
RNGFND_GAIN,0.8
RNGFND_GNDCLEAR,10
RNGFND_MAX_CM,700
RNGFND_MIN_CM,20
RNGFND_OFFSET,0
RNGFND_ORIENT,25 (Down - pitch 270)
RNGFND_PIN,-1
RNGFND_POS_X,0
RNGFND_POS_Y,0
RNGFND_POS_Z,0
RNGFND_PWRRNG,0
RNGFND_RMETRIC,1
RNGFND_SCALING,3
