Hello! I need help with my Lark weather station and have three main questions:

1. Device Connection/Recovery Issue: I'm having serious difficulties connecting my Lark weather station to other devices like Arduino or ESP32 boards. Now the situation has worsened - I can't connect it to any computer. Both Mac and Windows platforms are asking me to initialize the disk, but if I do this, all data will be lost!

Is there a way to restore the device to its initial state?Is the basic disk content available for download as an image file?Why is this happening, and how can I recover the original state of the Lark weather station?

2. I2C Communication: In which state/mode can I work with the Lark weather station via I2C connection? I want to send all measurements to a LoRaWAN device like a Heltec ESP32. So far, this hasn't been possible for me.

3. Gravity 4-Pole Connector Pinout: What is the connection schema for the gravity 4-pole connector? I assume:

Black = GNDRed = VCC??? = SDA??? = SCL

I haven't found any documentation about this pinout.

Thank you very much for any help or answers!

Thank You for your answers. After the formatting and reboot process, I will make - of course - some mores testing. I will document my steps when there are still some errors. Bye thank you again

1. Device Connection/Recovery Issue: Sudden power loss during system data saving may cause partition corruption on the USB storage. You can try using tools like DiskGenius to repair and recover the disk. After formatting the disk, the system will automatically regenerate the configuration files upon reboot. Reconnect the power afterward for normal operation.

 

2. I2C Communication: The system defaults to I2C communication, you can change the communication method in the first line of the config file on the USB flash drive.. Use the library from our Wiki to interface with Arduino/ESP32 for data acquisition: https://wiki.dfrobot.com/SKU_EDU0157_EN_Lark_Weather_Station#UNO%20Tutorial%20-%20I2C If you haven’t succeeded yet, could you specify which step encountered issues?

 

3. Gravity 4-Pole Connector Pinout: Using the 4-wire cable we provided:

Red = VCC

Black = GND

Blue = SCL/RX

Green = SDA/TX
