Trying to install sonar on my hexacopter and Mission Planner(1.3.19) will not allow me to check the box to enable sonar.
I have V3.2.1 in hexacopter and have made the parameter changes in the full parameter list (RNG…)
I can hear the Maxbotix sonar clicking but Mission PLanner will not allow me to check the box to enable the sonar. It’s as if the function is disabled. Any ideas?
