Guided_noGPS + Ras Pi not working

Hi everyone,

Recently I am working on a project to control Pixhawk with Rasp berry Pi running ROS and MavRos. I am sure that the communication between the Ras Pi and Pixhawk is set up, because I can view the copter status from the subscription topic in ROS. However, I am not able to get other substription informations such as battery and waypoints. Moreover, the pixhawk is not able to receive the attitude setpoint (mavlink ID 82) through MavRos when RasPi is sending the topic. The connection between Pixhawk and RasPI is through telemetry 1 port tx and rx pins.

Has anyone experienced anything like this?
