Hey y'all.
How far can it be, when using wireless updating? I don't have the crazyflie by hand, so i can't. Once upon a time, i develop a pair of device with Nordic nrf24l01+ and nrf24lu1+, these devices was developed as a wireless Arduino programming tool. The NRF24LU1+ was made to a Serial device. But when i test it the valid distance is about 5ms, it is so frustrated.

How about the perform of the Crazyflie and the Crazyradio?

Regards.

More than 50m

It might actually work that far but the wireless updating is a lot more picky as there can't be any lost packages. We have never tried more then a couple of meters as you sit next to your computer anyway, but we are interested in the result. The software could also be tuned to retry more often so theoretically it should be possible to make it updatable as far as the radio communication go.

I did a quick test in my house and it was no problem ~12m away.

Thank you TheFrog4u and tobias:
Though i don't have crazyflie, but i may find a stm32f10x board to instead and test the performance of the 2.4G wireless part, and expect to get some idea to improve my project WirelessDUEProg.

WOW, excellent performance. Now I'm sure that my project has some design defect.
