Flow Control

I start a new thread considering flow control as it might help other users to find it as well. As I see it, the flow control is done in software, since the USART6 has no CTS port on the LQFP64 package. However, there is a port used for NRF_FLOW_CTRL. In the explanation of the protocol you mention th...

Re: Minimal Messaging System for STM32

OK thank you. The syslink stuff seems to work. What I have problem with is the Radiolink apparently. If I change the channel and datarate from standard 0/0/2M to 0/80/250k with Syslink Commands, the Crazyflie client starts finding many different Crazyflies (see picture). Actually if I only change th...

Minimal Messaging System for STM32

Hello I'm still trying to run NuttX on the STM32. Since I don't want to change the Firmware on the NRF51822, I try to implement a minimal system on the STM32 such that I can send stuff using the Python or C library and then use it on the STM32. I realized that I don't get into the main loop but stuc...

Re: Flash over the air after manual flash

OK I could flash over the air, but now the blue light at M2 is constantly lit when powering on and the props dont spin as initialization. If I take flash over debugger, then it works. Edit: Now I can't even flash over the air anymore: make cload ../crazyflie-clients-python/bin/cfloader flash cflie.b...

Re: libcflie

Haha you got me there. Didn't think about that, because the Python scripts automatically detect the address and select it. Thank you very much.

Re: libcflie

OK I tried it but it didn't change. I realized though that if I run ex-gui I can't even see any movements there when moving my CF. I installed everything that was written in the readme file though.

Flash over the air after manual flash

I tried to install other Operating Systems on the Crazyflie. At this moment I want to set back the CF to its factory state such that I can flash the Firmware over the air. I tried flashing the cflie.bin over the ST-flash tool but I'm still not able to flash over the air. The CF is running fine thoug...

Re: libcflie

Thank you for the fast answer.
I first thought this might be the problem since I hade the same issue with the python examples. But then I tried also sending a 0 value and it didn't work. I will try the solution rshum19 suggested.

Re: libcflie

Thank you for the development of the library. I could build everything and also run it, but the crazyflie is not doing a move. I used the ex-simple file and just commented out the pitch/roll/yaw commands and set a fixed thrust to 20000. Is there any problem with the example? I'm using the VM0.6 from...
