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...

However, if we use more than 10 drones with a single dongle, communication problems always arise. Some drones do not ...

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...
