Need some directions on how to proceed. My project is semi-work and semi-hobby related so I have to disclose some information from you guys, bare with me on that.
What I’d like to do: Have a UNO connected to a device via RS-323 or LAN. This UNO would send text strings to the device via the serial or the LAN and wait for return text. Then the text would be relayed to another UNO via XBEE or NRF24l01. The user would then see from the UNO with the touch TFT messages and would also be able to send commands back to the UNO that connected to the device. The UNO with the screen has to be a portable device, hence the wireless technology.
The device I’m connecting to is on LAN so this is something I’d have to take into account.
I don’t really know what questions to ask you guys, more or less I’m hoping to spark up a conversation about this subject.
I’ll draw a picture for you guys…hold tight.
