how to measure rssi signal strength, or calculate the distance between transceiver nrf24l01.
sorry for my not very good english
base of the information here (RSSI of NRF24L01 - Nordic Q&A - Nordic DevZone - Nordic DevZone), "the nRF24L01 has no RSSI. Please consider using the nRF51822 instead. It has RSSI"
Even with a wireless device that shows RSSI values I don't think they will be sufficiently reliable to give a usable distance measurement. Wireless propagation is affected by many external factors.
If it was possible the Posyx system would not so expensive
