<![CDATA[Talkie Walkie like on radio frequences 466MHz or other frequences]]>Hello,

I have 2 M5Stack and I was thinking to make a "like talkwie walkie" system using radio frequences, I'm quite lost, I found arduino projects but nothing for M5Stack could you give me some ideas? I don't want to use wifi :-)
