how to import printed C console to node red

问题:

i'm using Dragino rpi Lora transceiver C code on the pi to send and receive packets to the Arduino .

the C code is working perfectly where it prints the received packets and the Signal to noise ratio and the timestamp , but i want to use it in node red . how can i import the received packet from the C console to node red ?

You need to use the node-red-node-daemon for long running processes that run until stopped and receive input via standard in and send results by standard out.
