The library does not seem to work with the new Microchip AtTiny's, at least with the AtTiny3216, but the Adafruit 5351 library does. I am using Arduino 1.8.15 and MegaTinyCore and the supplied example. The code compiles and runs but the chip does not respond. I have used the library many times before with Nano's and ESP8266's with great success and hoped to port our code to the tiny processors for our balloon trackers.
