APM 2.6 response only once after REQUEST_DATA_STREAM

I am trying to get mavlink messages from APM 2.6 via telemetry that is connected to my ordoid u3 usb port.
I am able to read messages when I send the REQUEST_DATA_STREAM message, but it sends them only once, I want to be able to get them continuously without needing to send the request again.

Any ways to solve this?
Thanks.
