BOOT Version: V3.0.0
*General
1. This is an entirely new firmware which is developed based on RAK SDK RUI. It is a baseline version, and we will release more new firmware based it.
2. A set of entirely new AT commands which are same with all of other RAK products which are developed based on RUI too.
3. A set of APIs which means you can develop your own firmware as you want by calling these APIs.
4. Add sleep mode. It has a very low power consumption: 10.3uA.
5. Add a bootloader. It means that you can upgrade the firmware from local or remote without jump BOOT pin whenever you want to do it.

*LoRaWAN
1. It only support LoRaWAN 1.0.2 now, which means that it can only support Class A and Class C.
2. There are two firmwares files, one is used for low frequency which includes EU433 and CN470, and the other is used for high frequency which includes IN865, EU868, AU915, US915, KR920, and AS923.
3. We've tested it, and it can work with TTN, loraserver, and LoRaWAN Server in all frequency perfectly.
