I work with Teensy3.2, DHT22 and lora module RFM9x (SX1276) with the frequency 868 MHz. I use the lmic library (link: https://github.com/matthijskooijman/arduino-lmic) but I had problems with radio.c ( ASSERT(v == 0x12 ). I use the SPI connection, the pins (CS pin10, MOSI pin 11, MISO pin 12, SCK pin 13) and
const lmic_pinmap lmic_pins = {
.nss = 10,
.dio = {2, 5, LMIC_UNUSED_PIN},
the code is functional with Teensy3.5 but not with Teensy3.2 and TeensyLC.

Thanks for your help
