2.4Ghz Comms Example?

[SteveJ]

Hi.,

Could anybody point me to a working example of a working basic IEEE  802.15.4 communication example, NOT Bluetooth, pure radio frequency in 2.4Ghz.
I spent about 2 months trying to figure this out for my WB55 series without success and can't waste more time now.
There are supposedly tons of examples on the internet, but all are Bluetooth, which I don't want. None for 2.4ghz RF.

The https://wiki.stmicroelectronics.cn/stm32mcu/wiki/Connectivity:Introduction_to_802_15_4 page is of now use as there is not example code. 

Thanks for any help or guidance.

Steve
