This app uses the RF-Sub1GHz module from Techno-Innov to create an example of a
transparent bridge between UART0 and 868MHz RF.

This example has been kept very simple, thus there's no check on what's
received on the serial line, which has to be valid RF packets (with first byte
indicating length and second byte indicating destination address or broadcast).

The RF-Sub1GHz module uses CC1101 transceiver to provide Sub 1GHz Rf
connectivity.

Depending on the version, the module also integrates a TMP101 temparature
sensor, the usual bi-color led used for status, a RTC quartz, a DC-DC step-up
for button battery power source support, and extension ports with a set of
gpio, including ADC, PWM, I2C, SPI, UART and SWD debug port.

Refer to the RF-Sub1GHz module's reference manual for more information.
