LoRa SX1278 and KL25Z

I am trying to use a LoRa module based on the SX1278 RF transceiver with the KL25Z MCU. The two devices are meant to communicate through SPI so I have developed a library to implement this, and then another library specifically for the LoRa SPI communication. The problem is that I am not receiving appropriate messages from the LoRa module in response to the commands I am sending.

Some key points...

-> I have tested the SPI library with Arduino and confirmed it's working;

-> I have developed a LoRa library to implement SPI communication specifically to address the SX1278 module based on the same library implemented in Arduino projects (I have simply translated from C++ to C);

-> I know the KL25Z is sending commands to the LoRa module as I observed with a logic analyser, but the RF module is not responding at all.

Does anyone know how to fix this?
