Implementing ble mesh on CF2

Hello, I am trying to implement the nordic semi ble bcast mesh implementation here . I understand that I may need to modify the crazyflie2-nrf-firmware, but it looks like both the sdk and soft device that the CF currently uses are a version behind the dependencies for the mesh implementation. Would ...

Re: Z-coordinate issues

Yes, it is definitely working better now. When I move it to different positions in the room, it does seem to find it's lock. Now it seems, though that flight is unstable. I'm not sure if this is still the z-axis issue or not. It seems like the CF takes off and then hits its setpoint, stops, but then...

Re: Z-coordinate issues

Unfortunately, that has not solved the problem. The CF still thinks it's way above where it actually is.

Re: Autonomous Flight Two Red LEDs

Thanks for the reply!

It turns out that I just needed to make callback functions for the enter and handle states of the uninit state. The drone would hang because it didn't know how to leave that state when the function it was calling was 0.

Tags as Anchors for Swarm Positioning

Hello, I am attempting to implement a system to make the Crazyflies broadcast their own position and avoid each other. I have 10 Crazyflies and the LPS system running well. I was wondering if I could set the LPS tags on the Crazyflies to broadcast their position like the anchors do? Would that be a ...

[Solved] Z-coordinate issues

Hello, I am trying to get the CF to take off on its own (without any commands from a computer). I have implemented code that will send setpoints to the commander based on a timer, but the CF doesn't take off because it seems to think that it is at 2.6 meters when it sits on the ground at 0 meters (z...

Re: Autonomous Flight Two Red LEDs

I've figured out that the CF will boot and act normal if I comment out the xTimerStart() in my autonomous.c (first code snippet), but then my autonomous function will not be called. Is there a known issue with this? Is there another way I could implement this?

Autonomous Flight Two Red LEDs

I have just implemented some code that is supposed to allow the crazyflie to hover autonomously (without the computer) based off the ICRA 2017 demo code for retrace. This is the code: #include "FreeRTOS.h" #include "timers.h" #include <float.h> #include <math.h> #include "stabilizer_types.h" #includ...
