you need to set the parameters of the distance in the advanced parameters tree… you need to set it in the RNGFND1 or RNGFND2…etc, it depends on how you have set it, but if you are using the tf mini you cannot use it as a proximity sensor but as an altimeter or Landing sensor…, so you have to disable the proximity sensor with 0.
if you want use the tf mini as obstacle avoidance and as a proximity sensor, you need to set it on an Arduino module… you must adjust few settings on the addresses but you need more than one sensor for make it as a real obstacle avoidance there is a topic of a developer who create a poc with tf mini) tf mini have also the lake that is unidirectional.
If you need a complete obstacle avoidance you can look for the teraranger evo hub with the correlated sensors like evo 60m or evo 600.
i want to use the tfmini to avoid a collision.
Only in one direction, forward.
Is there any way around here?
And one more question in a moment.
I switched one of the Tfmini to the I2c bus. When changing the address of the tfmini, an error must have occurred.
I do not know the address of the tfmini.
is there a way to scan the I2c bus to find the address?
if you have installed one tf mini you can use only as altimeter or Landing sensor, if you want use it standalone as proximity sensor you cannot use it as long as you will not use it with an Arduino board with the proper code…, for check and modify the add of the sensor you need a ttl serial board and with it you can check everything you need with the benewake gui tool.
Foward cannot be use… if you will set foward in RNGFND1 or 2, you will not have any measurement while putting the parameters down you will see the reading. You can reposition your module in front of your drone but i don’t give you any assurance about the behavior of your vehicle
I use the Tfmini plus on a daily basis for Simple avoidance, as well as path planning algo’s like BendyRuler. It is fairly easy to set it up… One can set any rangefinder to be used as a proximity sensor.
First step will be to configure RangeFinder properly: https://ardupilot.org/copter/docs/common-benewake-tfmini-lidar.html
