LoRaMac-Node - question about MODEM_FSK in SX1276.c to reduce code size

1

Hi All
I am looking at SX1276.c SX1276 driver implementation by Semtech. I noticed that the SX1276 Init sets the modem to MODEM_FSK as below:

void SX1276Init( RadioEvents_t *events )
{
    uint8_t i;

    RadioEvents = events;
------
---
    SX1276SetModem( MODEM_FSK );
  1. Can we start with setting modem to MODEM_LORA?
  2. And if we are going to use LoRa modulation only, can the code that handles MODEM_FSK be commented out to reduce the compiled code size?

Thanks :slight_smile:
