i working on pixhawk 2.4.8
and i connect it by 3DR radio
i programming on python by dronekit Library
I can’t get more than 10 readings per second by 3DR radio
Note that I reach about 200 readings per second when i connect by USB
what are the parameters should help me to increase the reading by 3DR ?
can you help me plz
10Hz is pretty fast for radio telem.
My radio is 433 MHZ
Is it reasonable that I can’t reach more than that with this radio?
That rate depends on two things:
- SR1_ (or SR2_) parameters that dictate update rates for certain classes of mavlink data,
- and indirectly Baud rate of the serial link.
SR0_ is for the USB port, SR1_ is for the serial1 port and so on…
The baud rate of the 433MHz sik radios can be increased but you will lose range. I have a set running at 115k baud (like USB) but I would only use them for very close range testing at that rate.
- Baud 115200
- Air 128
- Max Window 80
and you need to adjust your telem/serial ports to match of course.
