Hi Arnaud

Sorry for late reply. I tested it with different batteries. But it flies unstable as well. I have three batteries which are all used for 12 months. I'm not sure is it because the battery quality.

Thanks

Re: Crazyradio connection problem

usb connection is also a possible method. Another problem I met is radio loss. When I put crazyflie within 1m of crazyradio, it can be connected. However, the connection is unstable.

Re: Crazyradio connection problem

It looks like I didn't set crazyflie address correctly.
I checked drone address over usb cable and set the adress to client software. It now can connect to crazyflie !
Just thinking it might be better to have a function to scan drone address automatic.

Thanks

Re: crazyflie2.0 cannot enter DFU mode

Hi Arnaud

There is another problem I'm not sure. How to flash firmware for NRF51 on crazyflie?

I checked the wiki https://wiki.bitcraze.io/doc:crazyflie:dev:starting. But I'm not sure can I flash NRF51 firmware over radiolink? It seems it require SWD cable and looks complex.

Thanks
