I just only want software UART (bit-banging) for my receiver that's all.

What would you have the bit-banged UART do that the hardware UART does not do?


Okay, I tell what happened. I tried to implement serial communication using with hardware UART in order to transmit simple byte to another microcontroller with RLP-434 which also implement hardware UART. In my transmitter code, I simply send two different byte (0x01 and 0x02) which forece my receiver to switch red LED on and off, delay few seconds then swithc blue LED on and off.

I tested it and learnt that the blue or red LED would not switch on. So I suspected it was antenna but I am not 100% sure because I put two core wire about 10 inches in the transmitter and receiver. Since I don't have plenty of money and I prefer to test it with bit-banging (software UART) in order to see if it work better.

According to the data sheet for TLP-434 and RLP-434, it need 5ohm antenna. Can't I make it or I need to buy it?
