#86238 - UART is not a good choice
Responding to: ???'s previous message
Stephen Harris said:
... but heres the link ...

And that product's datasheet, in the typical application section, refers to another datasheet for an encoder/decoder chipset that uses Manchester for its balanced code. Thus you can infer that the RF link 'likes' a DC-balanced encoding scheme and thus an MCU's UART is not a good choice. You'll probably want to consider bit-banging a Manchester or 4B/5B coding scheme.
