Hello
I have a Wireless Stick Lite (Panda Board) and I use VSCium or Arduino when I run the Wireless Stick Lite factory test code sketch

- HelTec Automation™ 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.
