Large size topic transmission problem [4740].

[OpusK]

Hi

We use Client and Agent in RaspberryPi to transfer the LIDAR data in TB3.

• Turtlebot3 LIDAR client

We have been using the LIDAR data of 360 degrees to 180 degrees so far as it is urgent.
But now I want to transfer all the data from the Client.

As a result of my testing, up to 240 data can be transferred without any problem. However, starting from 241, the following error occurs in Agent.

Error written data on DDS entity.

I did not calculate the exact size of the data, but when I send 240 data, it contains about 1000 bytes if I include the remaining data.

Let me know if you need more information.

Hi, @julianbermudez

This method does not work.
There may be a problem with my XML expression. So, can you give an example of how to write XML for writers and readers on the client? (including details about datawriter)
