RAK5205-WisTrio-LoRa firmware version 2.x.0.2
1.Fix "at+msg_confirm:x"was invalid bug.
2.Fix "at+set_config=pwr_level:x" was invalid bug.
RAK5205-WisTrio-LoRa firmware version 2.x.0.0
1.This Firmware is based on LoRaWAN 1.0.2 protocol ,support Class A and Class C mode.User could switch the mode by such as 'at+set_config=class:2' command,0:class A,1:class B(unsupported),2:class C.
It supports almost all frequency bands:(HF)->EU868, US915, AU915, KR920, AS923，IN865. (LF)->EU433，CN470.
2.The Firmware folder contains two firmware: "RAK5205_LF_trackerboard.bin"and"RAK5205_LF_trackerboard.bin".
"RAK5205_HF_trackerboard.bin" surpport region:EU868, US915, AU915, KR920, AS923，IN865. "RAK5205_LF_trackerboard.bin" surpport region:EU433，CN470.
Tips： Region switch by such as"at+band=EU868"command.
AT command refer to RAK811 Lora AT Command V1.4.pdf.
3.Method of The Demo project generates different firmware refer to ReleaseNotes.txt.
4.the manual of RAK5205-WisTrio-LoRa refer to RAK5205_User_Manual_V1.2.pdf
