Activating IMU on PDoA tag and node

Hi, I am trying to pull the IMU data that is sent to the node and use this data for localization. Currently I am using a serial library to send the “node” command and then parse through the output. However, all the IMU values are reading as zero. I tried using the “ADDTAG” command as it explains that this will activate the imu functionality, however it seems that this functionality is just used to determine if the node is stationary or not. I have the PDoA node application running and the X, Y Z parameters are all zero. How can I make then display the IMU values?
