I wanted to have the possibility to set the TxPower of my sensors so nearby nodes can be set to a lower power to save the batteries. I changed in my local copy of LoRaNow the following to add this (the sf was already in the lib, but I set it in the text for orientation):
LoRaNow.h:
define LORANOW_DEFAULT_SF 7
#define LORANOW_DEFAULT_POWER 10
class LoRaNowClass : public Stream
{
private:
uint8_t sf = LORANOW_DEFAULT_SF;
uint8_t txpower = LORANOW_DEFAULT_POWER;

void LoRaNowClass::txMode() { LORANOW_DEBUG_PRINT(millis());LORANOW_DEBUG_PRINTLN("[ln] txMode"); LoRa.idle(); LoRa.setFrequency(frequency); LoRa.setSpreadingFactor(sf); LoRa.setTxPower(txpower);
== Maybe this addition is also handy for other users.
