I'm also trying to install wireless camera on my crazyflie, and I already got stuff ready.
This is what it looks:
I can already acquire video through VLC media player. However, when I try to connect to the Crazyflie at the same time, the client can't see the file. Then I removed the power supply to the FPV system, and the flie was detected. I first thought that was because of the channel crash, but after I changed the flie's channel to some other channels, the flie still can't be detected. Have you ever met with this problem? What are your settings? I'm using 2414 MHz for the video signal, and I have tried the flie's channel at ch 1, 10 (default of the Crazyflie), and 110.
: I changed to ch 110 and now I can connect both crazyflie and video at the same time BUT the signal is not stable. Link quality is worsened and sometimes lead to signal lost. Anyway, I tried unplugging the supply to the voltage regulator, and the connection is stable like normal. I also tried putting another crazyflie close to the one with camera, connecting at adjacent channel (110 vs 111) and the one without camera can also connect with no problem. At this point I think it is not the problem of interference of the frequency. What I doubt is whether my circuit has some problem, or the camera system draws too much current causing drop in the crazyflie's transmitter power.
I'm using this transmitter
, with Pololu
step-up/down voltage regulator. On the receiver side, I'm also using an EasyCap USBTV007 Wireless receiver.
I also have a problem of getting video from the EasyCap USBTV007 on ROS, as I have asked here
: I found out that I burned the regulator U9 on the crazyflie!!! It came to my mind that I have got similar problem like this before but that time was more severe: the connection was lost quicker than this time (See here
for reference.) So I measured VCC pin and it was 2.1 V instead of 2.8 V. Then I also found that the voltage regulator was well swollen and I remember seeing some smoke coming out from the flie. This all binds together and I decided to change the voltage regulator (what a tough task!) and finally can now connect to both crazyflie and video at the same time.
Anyway, I still cannot connect my EasyCap USBTV to ROS. If anyone knows, please
