+ * HelTec Automation(TM) Wireless Stick Lite factory test code, witch include
+ * follow functions:
+ *
+ * - Node A search WiFi and send WiFi AP number to another node B via LoRa, Node B
+ *   will send a string "abc" back to Node A, if Node A received "abc", test pass.
+ *
+ * - Basic serial port test(in baud rate 115200);
+ *
+ * - LED blink test;
+ *
+ * - WIFI join and scan test;
+ *
+ * - LoRa Ping-Pong test(DIO0 -- GPIO26 interrup check the new incoming messages;
+ *
+ * - Timer test and some other Arduino basic functions.
