Hi,
I'm starting a new project for a client that needs a 433 MHz transmitter and receiver. The distance between the 2 communicating devices will be fixed at approximately 5 ft apart. There will be potential obstructions of metal between the 2 devices. The data to communicate is 1-way only, and is just the value of a switch (open or closed).
Can you recommend hardware and firmware (including starting example code) that can handle this requirement?
Is there an existing firmware protocol stack for something like this? I need to understand the firmware effort required.
Thanks...
Brian
- I don't see that you need a protocol stack for this since it's a one way system and just two devices. As I understand it, the TX side just have to send one packet with a few bytes that the receiver reads as on or off.
- You caan choose either to use a tranceiver + MCU or a wireless MCU. Either CC113L/ CC115L or CC1310 is what I would recommend.
- How does the metal obstruction look like?
Thanks for the pointers to devices. Is there example code somewhere that shows how to interface to the CC113?
The metal obstruction would be something along the lines of a car door.
