Hi All I am new to this forum, I just join to this site today. I do need some help about writing the code for NRF24L01 with multiple pipes. Basicly 3 transmitters and 1 receiver. I am planing to do the project by using NRF24L01 to power on the garage (Not Open the garage). I have 3 cars. me, my wife and 1 very old car (most the time the old car stay home). If 2 cars out the house then power off the garage. if my wife's car or my car home then power on the garage. If I use the NRF24L01 then how can detect the what pipe not receive signal to turn off the garage vise versa. I am not concern the string or data. I concern the transmit and receive connectivity. I did try to use bluetooth HC-05 but the range is short did not work well (from garage to the car park about 30ft). all you help will be appreciate.
Thank A lot
