RF Link between two SX Chips

Wireless & IoT

Hi,

I have two SX28’s and a RF Link - 4800bps - 434MHz. I want to send radio commands from one SX to another. I was wondering if anybody had any idea how I should program it.

Getting UARTs working on the SX28s would be a good start.

Yes but I already have the RF Link from SparkFun and need help using that.

You still need to communicate with them.

Would something like a MAX3100 work and how would I use that?

6

Software UARTs are usually used with the SX28.

I clearly know nothing about UARTs. Some sample code on these software UARTs would be greatly appreciated.

There’s lots of software around for the SX28, including UARTs.
