try the latest commits - you need to install it manually since it will take a day for the version to get updated in the library manager note we havent tested it with samd21 it ought to work, but its not tested!
Thanks, apparently your las commit fix the problem!!
I experiment whit this library for a while with samd21 and it worked good for my project
I made a little modifications to fonaTest example for use it with samd21
https://github.com/wifixcort/samd21_examples/tree/master/SAMD21_examples/samd21_fona_test
I update my Adafruit_MQTT library this morning and compile as few days ago. Now in my sketch I see this compiling error. I use SAMD21 for this!!!
cannot declare variable 'mqtt' to be of abstract type 'Adafruit_MQTT_FONA'
It referes to this line:
Adafruit_MQTT_FONA mqtt(&fona, MQTT_SERVER, AIO_SERVERPORT, MQTT_USERNAME, MQTT_PASSWORD);
Is the same code I always use, I just "update" your library. Testing if I have something wrong I try to compile your mqtt_fona example include with the library, selecting Arduino UNO board, and I got the same error.
Something helpfull could be this errors with the library and debug redefinitions:
