How can I see the transmitted data from PSDK on Mobile SDK?

Hi, I'm now trying to send int value from PSDK to MSDK for around 10 times per second.

So I followed the tutorial of data_transmission, but I can't find window anywhere on the MSDK to see the value. (https://developer.dji.com/doc/payload-sdk-tutorial/en/function-set/basic-function/data-transmission.html)

PSDK works well and no errors were reported.

Where can I see this value. (= "DJI Data Transmission Test Data.\r\n" in test_data_transmission.c)

I have successfully send video streams to RC and control X-Port, so I don't think there is something wrong with device connection or settings.

Or is this function only for Android MSDK?

##What I use

M300RTK

PSDK3.0

MSDK V4 for IOS

Xport

raspberryPi
