   I discovered an interesting fact (that at least happens for TTGO_LORA32 board) :
   If CONFIG_LPWAN_SX127X_MODULATION_DEFAULT=3 the `sx127x` app doesn't work on LoRa mode (-m 0), but works on FSK mode (-m 1). If CONFIG_LPWAN_SX127X_MODULATION_DEFAULT=2 the app will work fine for LoRa and FSK mode, but not for OOK. If CONFIG_LPWAN_SX127X_MODULATION_DEFAULT=1 none mode will work.
