Rangefinder not showing in Mission Planner Data

[Alberto_Ds]

Hi @johnmeeel ,

You could try this sonar, it works connected directly to the FC and doesn’t cost much. The range is small but it still works. Here you can find info and some videos.

Sonar Maxbotix only be used pointing down?

I have a sonar MAXBOTIC i2c that works if I put 25 in the full param list, but I would like to use it as a front sensor to avoid obstacles. However if I put 0 the reading stops and I always get the message “Prearm prx1 no data” [image]
