Hello, friends.Firstly, sorry for my bad english.

I'm testing data transmission with M200 drone, and using PSDK development board, which is recommended from DJI, STM32F407-EVAL.
I saw that the board's OS is freeRTOS and then I can't use High speed data transmission.
I thought that when I transmit data, the channel of data transmission is UART ( Command Channel ), and the bandwidth is <=3072bytes. ( Channel and Bandwidth Information is from Document )

With those information, I wanted to know the exact bandwidth, so I tested with my Dummy data Transmitter.
When I sent about 2000bytes data per second, the App(developed with MSDK) ran very well.
But, when I sent about 2500bytes data per second, the App went down.
About this two test, I just think that, with real drone control command, the bandwidth can be smaller.
However, when I sent 20bytes per 0.01second, the App went down or the portion of data was taken.
How can I explain this problem, and handle it...?

Have you ever handled this problem like data transmission with freeRTOS board?
If I want to use High speed data Transmission, what should I do?
Is there no way without using Linux OS?

Thank you for your advice
