I'm going to read somthing about it!!! Do you think that this goal is too much difficult for a beginner like me or it wold be possible?

Re: change log rate

So, let me to understand better. For example, if I have this code: gyroconf = LogConfig("Gyro", 10) gyroconf.addVariable(LogVariable("gyro.x", "float")) gyroconf.addVariable(LogVariable("gyro.y", "float")) gyroconf.addVariable(LogVariable("gyro....

comunicating crazyflies

Hallo!! I don't have any knowledge about the comunications between two devices. I would know if is it possible to make two comunicating crazyflies. It would be nice that one crazyflie could send some numerical values to another crazyflie!! Could you give me some suggestions to make it possible?? Che...

Re: Quadcopter follower

Hi, I'm working on a similar project. I want to implement a swarm of quadrotor. The problem is which sensor we can add to do this. For example i would that each cf knows the distance from the other cf (without some external tracking systems).

change log rate

Hello! I configured and started a log package at one frequency f1. Then i would change its frequency. I'm trying using this code: log_config.setPeriod(1000/f2) If then i do log_config.getPeriod() i found the right value but the real log frequency seams to be unchanged!! May be i have to stop the log...

[SOLVED] Disconnection after few minutes

Hallo! I'm developing my own software for control the crazyflie (using your library). For now i can fly with it: i can read data and send commands. When i'm testing it, for example when i want only to read the data, after some minute since the connection suddenly the crayflie turns off. Could you sa...

Re: Trying to log data while also sending setpoints

Great, thanks for the info! For what it's worth, I seem to have resolved my initial logging issue by separating the command and logging calls in to their own threads. I think I may have been running in to a race condition trying to log before/while the setpoint was being sent. Without any additiona...

Re: Trying to log data while also sending setpoints

In the master thesis we where involved in there are some good information about the link and bandwidth. The packet rate is currently limited by the USB which is 1000 packets/second. Each packet is max 32 bytes data so 32k/s is the current limit. We have not tested high speed logging that much so th...

Re: Trying to log data while also sending setpoints

Hallo!!
I want to understand the maximun performance of the link too, and how to reach it!
I mean how many variables could be sent in the same package? What's the maximun rate? And in this condition what is the maximun rate of the set point request??
