Crazyradio connection problem

Post by chuhao » Wed Jul 12, 2017 3:12 am

Hi

I meet problem to connect crazyradio with my PC.

I installed crazyflie client on my Ubuntu 16.04. I start the client software, and cannot find crazyradio connected.

Then I tried to check devices,

Code: Select all

lsusb
It shows,
Bus 002 Device 002: ID 8087:8000 Intel Corp.
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 8087:8008 Intel Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 002: ID 062a:4101 Creative Labs Wireless Keyboard/Mouse
Bus 003 Device 016: ID 1915:0101 Nordic Semiconductor ASA
Bus 003 Device 004: ID 214b:7000
Bus 003 Device 003: ID 1a2c:2124 China Resource Semico Co., Ltd
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
I thought device name should be "crazyradio PA USB", isn't it?

So, I tried to flash a new firmware to crazyradio, After,

Code: Select all

python usbtools/launchBootloader.py
It says
BootLoader started
. Then, check with

Code: Select all

lsusb
, the listed devices does not change at all.
If flash a new firmware by

Code: Select all

python usbtools/nrfbootload.py flash cradio.bin
, it shows,
('Found nRF24LU1 bootloader version', '18.0')
Flashing:
Flashing 7471 bytes...
Flashing done!
Verifying:
Reading firmware/bin/cradio.bin...
Reading 7471 bytes from the flash...
Verification succeded!
After the whole firmware flash process, I enter

Code: Select all

dmesg
, it shows,

When you start the client and when you click "Scann" do you see the RED LED on the Crazyradio lighting up?

If so, the "select an interface" dropdown menu will show all powered-on Crazyflie detected (both radio and usb-connected Crazyflie). You should then be able to connect it.

The Crazyradio is VID:PID 1915:7777, the Crazyradio USB bootloader is 1915:0101. From your logs, there seems to be no problem with the Crazyradio USB connection.

If scanning from the client does not work, check that you have the user right to use the Crazyradio: https://github.com/bitcraze/crazyflie-l ... ermissions

Hi Arnaud

After start client, it still cannot found devices. The log showed on terminal is showed as below,

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

Scanning drone address would be hard and and it is actually a feature: right now the link has no protection but switching it a different address makes it harder to connect accidentally to the drone.

One thing I have been wanting to do for a while is to have the Crazyflie broadcasting its identity when not connected, this would allow for a passive scanning (this is how wifi works for instance). I guess it would solve this problem. But until that is done, the USB connection is the way to recover a Crazyflie from a random address.

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. Especially when I move the drone further than 2m to crazyradio. It always lost the connection.

Is there any way to improve it?

Thanks

What radio parameters are you using? 2m range with a Crazyradio PA is not normal and surprising, we are observing much more range.

I use radio with parameters: radio://0/100/2M/E7E7E7E701

OK, do you see any difference if you try a lower channel like 45?
