Communicate with Crazyflie with BLE alt_hold

I have checked the python client code, where you can set the altitude hold enabled by setting the param alt_hold to true. I wonder if this is possible by using BLE from an iPhone. That means, setting the param alt_hold to true by BLE. If yes, what's the characteristic value I need to communicate to ...

Re: Implement PID control on iOS client

First thing what kind of PID control are you thinking about? Position PID control? I don't think any lower level control will work as the latency is to big over BLE. I know it has been done using the Crazyradio but that has much lower latency. So what's the typical low latency required to make Posi...

Implement PID control on iOS client

I want to implement PID control on the iOS client side. From the ios-client-example, I know how to control the thrust output etc, but how can I get the sensor output from crazyflie (yaw,pitch,alt,acceleration.. etc) I read a post saying I can log those parameters, but I am not very clear how to star...

I have browsed through several thread on this forum, about adding FPV to flie. They all u...

Re: Craziflie 2.0 not respond to iOS client

OK, I seem to have found out the trick. Every time I restart the flie, I need to place it horizontally, only after I do that it will start to accept the command.
Is that something bug or maybe a safety precaution? :D

Craziflie 2.0 not respond to iOS client

I just assembled the craziflie, and I downloaded the iOS app. I tried to control the flie from my iPhone 5s. Bluetooth was turned on and the flie was connected. However, when I tapped my two fingers on the screen and moved around, nothing happened to my drone. Anyone know why is that? I can see the ...
