How to set mb12xx sonar to use it as Z value in local\_position? As I understand if I will set EKF2\_HGT\_MODE as Range sensor it will not help me with mb12xx.  
I`d like to use to local pose px4flow(without rabge sensor) and mb12xx as range sensor, but not to use baro and GPS. Is it possible? May be it`s possible to do this from code?

It posts data to distance\_sensor, but I`d like to see this data in locale\_position\_ned.z
