transmit power and nrf
Hi! We are continuing to study Python code and firmware code to see if there are even dozens of drones that can communicate seamlessly. There are two questions. I found that I could adjust the transmit power of the nrf51 on the drone firmware and adjusted it to 4dbm (the default value is 0dBm) to se...

Communication errors and abnormal values in multiple drones
Hi! These days, we have got 50 crazyflies and try to make drone show. But there are some problems. We use 8 anchors, TDOA mode in 5m X 5m X 2M. 1. We want to fly more than 10 drones. However, if we use more than 10 drones with a single dongle, communication problems always arise. Some drones do not ...

Hi, these days I have been trying to modify several example codes and it is successful! But few days ago, loco positioning system was disfunctional suddenly. Drone's location was very irregular even though I used just original example code. For example, if i order the drone to move at (3,4,2), then ...

ranging data
I found some posts about peer-to-peer communication between Crazyflies but there were no exact explanation. I want to use other drone's real-time information. I can get ranging data from loco positioning node to drone with positioning deck(DWM1000). I wonder that if it would be possible to get rangi...

I followed a post (https://github.com/bitcraze/crazyflie-lib-python/issues/72) but it still doesn't work. I have previous version of crazyflie-lib-pyt...
