The “Sensortag” mode on weather station already sends out the accelerometer data, download latest version from ruu.vi/setup and update the firmware. After the firmware has been updated, press “B” to enter sensortag mode. Red led blinks once per second in sensortag mode.
The accelerometer data does not fit in URL, so the data is sent in binary. You can use one of the data collector libraries presented in forum to read the data.
You can modify the configuration to change the transmission power in weather station and the base URL main. Please note that the base URL cannot be any longer to still fit the sensor data.
