Hi all, my ping2 sensor is working fine but when connected to mission planner its not showing the sonar reading and giving pre arm message as rangefinder1 no data. Even after configuring all the parameters and connections correctly. Please suggest to solve this issues.
Hi @Prashanth_u, welcome to the forum 
Can you provide some more information about the system , connections, software stack, and parameters you’re using?
My best guess at this point is that you have something configured or connected incorrectly, but with limited information all we can suggest are limited ideas.
@EliotBR Thank you for the getting back. I am using pixhawk 1 flight controller with ardurover, software for to test sensor ping viewer but to configure ardurover we are using mission planner.
And configured parameters as
Serial2_protocal= 9 rangefinder
Serial2_baudrate=115
Rangefinder _type1= 23
Rangefinder _min_cm= 10
Rangefinder _max_cm=2700
And I have given 5v bec to power sensor and Tried by changing tx and rx but still sensor is getting no data and in mission planner it’s showing rangefinder 1 no data.
Please help me to resolve the issue.
