Node-Red, Firmata and NRF24L01

Hello.

I have two programs that work separately; one using Firmata to communicate between Node-Red on a RPI and the Arduino UNO(taken from the Arduino examples, called Standard Firmata), and another that sets up serial comm over an NRF24L01 2.4GHz transceiver. But when we try to combine the two codes, we no longer get the serial comm over NRF24 to work. Could it be a problem setting up both firmata.begin and serial.begin?

Could it be a problem setting up both firmata.begin and serial.begin?

How do you suppose Firmata communicates with the other computer? If you guessed Serial, you win. So, you can NOT use Serial independent of Firmata.

The usual nRF24L01+ modules connect via SPI rather than serial. If you have a module that uses Serial please post a link to it.

I know nothing about Firmata.
