I have been toiling away at this project (sketches attached) and now its time to “ask an Expert” !!
I have written code for TX & RX utilising 2 x NRF24L01. All functioning.
The Transmitter (UNO + NRF24L01 + Data Logger Shield) monitors 3 x analog inputs, transmits CSV & logs CSV file to SD card, constantly.
The receiver (Nano + NRF24L01) receives CSV file, constantly.
Almost perfect !
Would some-one (“Arduino Guru”) be able to advise of the required modifications to sketch to enable a “Latching Pushbutton”, located at Receiver (Slave) to “Start & Stop” recording of data on SD Card only. Transmission of Data to Receiver to continue “at all times” (only start & stop SD card recording).
I would greatly appreciate any recommendations/assistance offered.
Thanks in advance
