Hey guys,
I have been trying to establish a communication interface between the Arduino Uno and the NodeMCU 1.0 ( ESP-12E ) for a project where I need to read data from the NodeMCU and transfer it to the Arduino Uno - to which a radio transreceiver module is connected ( nrf24l01 ) - for data transmission.
I am not using the built-in WiFi module of the NodeMCU to transmit the data as the range is restricted to a few metres whereas the nrf24l01 has a range of around 1000 m. Also, the NodeMCU provides a much faster CPU frequency ( 80 / 160 MHz ) in contrast to the Arduino Uno which maxes out at 16 Mhz, thus, making NodeMCU a much better alternative for reading real-time data.
I have also tried interfacing the nrf24l01 with the NodeMCU directly but my attempts to do the same were futile.
Please advise me as to how I can easily transfer the data read by the NodeMCU to the Arduino for the radio transmission. Or if possible, please suggest a way to interface the nrf24l01 radio transreceiver with the NodeMCU so that I can eliminate the need to transfer data to the Arduino Uno.
Thanks in advance. Any help would be appreciated.
