RFM69 433 MHz and 900 MHz Featherwings used at Same time

by chickpeas75 on Thu Jul 29, 2021 7:32 pm

Hello,

I have a project where I need both a 433 MHz and a 900 MHz Featherwing RFM69 Radio listening at the same time.
I know using SPI I can allow one of the radios to communicate to my Feather Huzzah-32 ESP32 if the other radio has its SS or CS pin set to HIGH, but how do I account for the case where I need to toggle between radios based on when each radio receives a signal? Is there a way to set HIGH quickly to the other radio's SS/CS pin when one radio receives a packet?

Thanks
