How do I change the LoRa settings for the following for example?
- carrier frequency
- spreading factor
- coding rate
- sync word
- preamble length
- buffer size
- output power during transmission
Can we update these settings in the LoRaSender example files that use the heltec.h library?
Can we use the same format as for the LoRaWan_APP library? eg #define RF_FREQUENCY 868E6, or is it something different for the heltec.h library, like #define BAND 868E6?
