* `frequency` - new SPI frequency to use, defaults to `10E6`
* `frequency` - new SPI frequency to use, defaults to `8E6`
This call is optional and only needs to be used if you need to change the default SPI frequency used. Some logic level converters cannot support high speeds such as 10 MHz, so a lower SPI frequency can be selected with `LoRa.setSPIFrequency(frequency)`.
