Hi at all,

I want to implement a program that localize a Crazyflie 2.0 Quadcopter. Four Crazyradio PA's will be represented the beacons and the localisation is based on trilateration. In the stock of the new firmware is now included the RSSI measurement:
https://github.com/bitcraze/crazyflie2- ... /src/esb.c
But this code isn't documented. I'm totally new in programming a crazyflie. How can I use the methods? Did someome got experience with the RSSI measurement?

Best regards

Hi o_boo,
You might like to check out this recent blog post from Bitcraze if you haven't seen it yet...

Also, for the RSSI question, you might like to check out this comment from this blog post.

Or maybe you've already seen those?

I do not know of anybody successfully using RSSI for location. The rssi values typically have a very large variance, which gives uncertainty up to several meters. It can be used to check which room something is in, but not accurate location.

But please prove me wrong on this, it would be amazing
