Connectors

Alpha Version

Until now, it is not possible, to configure the WiFi settings via the Android app. The user has to configure it with a serial adapter cable (UART, 3.3V or 5V).

Configuration with UART adapter

  1. Connect the serial dapter cable to the WolkenThermometers „Arduino Programming Port“ P4
    Important: do not connect Pin 4 (reset), because then the push button is disabled
    I'm using the FTDI UM230XB. You can also use another Arduino board (e.g. Arduino Nano), when you shorten the RST of that board to GND, and connect Rx with P4.3 and Tx of that board with P4.2.
  2. Connect a battery
  3. Open a serial terminal application on the computer
    I use cutecom on linux. For Windows I recommend hterm
  4. Terminal Settings:
    1. Baudrate: 9600 baud/s
    2. 8 data bits
    3. no parity bit
    4. 1 stop bit
    5. line break: LF only
  5. Check connection by pressing the reset button.
    You shoud see a message like this
    Project: WolkenThermometer V1.0 
  6. Then press and hold the reset button, until the counter is between 4 and 8. This is the way how you enter the setup mode.
  7. Follow the instructions of the configuration dialog. Here a full demo configuration:

    The configuration is finished. Please go on with the smart phone app
  8. Unplug the UART-cable
  9. Restart the firmware by pressing the reset button shortly
  10. After about 20s the first measurement data should be sent to the server
  11. Check this with this url:
