I was wondering what actually happens when I do not use the SF parameter while intilaizing LoRa settings like this
lora = LoRa(mode=LoRa.LORA, region=LoRa.US915, sf=9, coding_rate = LoRa.CODING_4_8, tx_power=20, rx_iq=True)
here I have used SF 9 what if I remove this parameter does it mean that there would be no SF applied ? or will the default of SF 6 be chosen.
What should i do, if i dont want any FEC at all? Do i just remove this parameter as well or by default will some value be applied.
