I have and issue to give a solution.
I have two stations which are located 100m away from each other and i want to transfer strings from one statins to another. Master station is the always sending msgs to slave station. Slave station i only need to receive the string msgs and display in display board.
Since my master station has the PC what i tried first is made python tkinter gui and give master facility to enter his desired string msg and then by python i sent the string to arduino board and then transfer that master arduino data to slave arduino. Then i tried to display that slave arduino data on slave station P10 LED board. The process was quite hard with a lot of wiring and i don't think this is a reliable system since i want to run this system 24*7 hours per week.
What i want to ask from you is is there any opportunity that i can use two R-pies at master and slave stations and display that on PC monitor by using node red. Up To now i am thinking connecting those two R-pies via ethernet cables.
I am still at planning stage of this Use of R-pie for this project. Before i purchase hardwear i want to know that above mention is good or not? Is there any other reliable good method to do this task? All i want is transfer STRINGS from master to slave and display at slave station. Master station also need to display what he has sent to salve.
