Hi, I am thinking of using the nrf24l01 board from Banggood ([here]) to build a transmitter/receiver set for r/c model planes. However one of the things I would like to do is implement a range check function. On most commercial transmitters there is a setting that reduces the output power of the transmitter by about 90%. In this state the operator walks away from the model (usually about 40-50 paces) and checks that the radio is still working (or checks the RSSI if it is a telemetry radio). If all is okay he can be fairly confident that the range is okay. My question is, is it possible to reduce the output power of the nrf24l01 chip by software control somehow, or maybe by reducing the voltage provided to the board? I'm happy to experiment and find a suitable value for voltage or whatever may be required to reduce the power, but just wondering if it's possible, and if such a test would be valid? Thanks, Ian PS I couldn't figure out how to add tags, sorry.
