i'm new to Node Red , i'm working with a Lora Gps Hat.
i have raspberry C code to send Data and another to receive data . the Lora hat can't be receiving and emitting at the same time
i have tested the exec Node to send data it's working perfectly
and i used a daemon Node to receive data also it's working
what i like to do is when i need to send data from the pi to the Arduino
i want to stop the receiving daemon node ,run the send exec node , then rerun the receiving daemon node
