My notes howto make B-L072Z-LRWAN1 can use lmic in arduino, i’m using standard lmic and this library can’t work until you add manually pin spi at your setup.
SPI.setMOSI(PA7);
SPI.setMISO(PA6);
SPI.setSCLK(PB3);
And you can use this pinout
// Pin mapping
const lmic_pinmap lmic_pins = {
.nss = PA15,
.rxtx = LMIC_UNUSED_PIN,
.rst = PC0,
.dio = {PB4, PB1, PB0},
};
For complete code you can see at my github here
