It allow to send receive data over air and could be useful for debugging radio communication and protocols. It is still in beta release, so I will be glad to any feedback, notes, constructive critics and advicesRFM75pythonFT232ftdihttps://community.element14.com/challenges-projects/project14/rf/w/setup/26951/featured-content-triptych-setup-docMon, 06 Dec 2021 01:50:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:4e180fc3-7759-41a5-91a6-1b6442360d30tariq.ahmadGot mail!
