Ros2 bag deserialize

edit

Hi everybody, I have problem related to the reading of the data contained in a bag. I've recorded data coming from sensors in a bag (.db3) and I would like to read this with sqlite browser, but the data column is filled with BLOB since the record produces binary stream data. I've seen on internet that this problem is related to the serialization of the messages sent over the topic. Is there a simple way to deserialize it, using python?
