FP_A-ODOMSTATUS

This message is available from the firmware version 2.102.2

Description:

This message contains information regarding the internal status of the Fusion engine. It is output at the configured rate (i.e., alongside other messages, such as the FP-A_ODOMETRY message).

We recommend using this message to observe all parameters' status. Note that the information will not align with the status of, e.g., FP_A-ODOMETRY. This is because the status in the FP_A-ODOMSTATUS message refer to the internal Fusion logic. Therefore, the classification of each parameter state is done differently and thus the values are only fully available once Fusion is initialized

Example message:
