Multiple MaxBotix I2C Pixhawk 2.1 problem

Pixhawk
1

Hi

I have multiple MaxBotix I2C sonars, my idea is to use one as obstavcle avoidance on the front and the second one pointing down to measure the high. Each one will work fine alone, but when i plug the sencond to the i2c riel seems like to interfer each other. So I have change the address of one of the sonar, but any address different to the 224 make the sonar stop working on the pix.

Another thing I realize is the PixHacwk 2.1 only get the rngfnd and never the rngfnd2.

Im missing something? Any one did sonmethin similar?

thanks!
