Amount of data to send using telemetry SiK radio

Hi,

I am trying log multiple signals using the telemetry radios. However, I see data drops. Currently I am sending 4800 bytes/second and the baud rate in the serial port is selected to 115200. In the SiK radio configuration in mission planner I configured there also the baudrate as 115200 and air speed as 250kbps. Still, I see data drops. Is there any limitation on how much data we can send? Considering 10 bits/byte I thought I can send 11520 bytes/second. However, I data drops with this only. Is this because of Mavlink encapsulation or something?

Can anyone please help me understand this?

Thanks,

Sayan

there is a small python application that calculates the real size of the data being transferred

It calculates the mavlink overhead.
