The technology behind Freedrum is constantly evolving, so the programmers behind the project make periodic updates to the firmware. These updates are aimed at improving the overall performance of the sensors as well as their connectivity.  Be sure to be on the latest firmware so you can get the best out of your drum kit and also to avoid running into bugs and other concerns. Freedrum Sensorware is the app that lets you update your firmware. It can be found on both Android and iOS app stores for free.  Once you have the app downloaded, follow these steps to update your sensors : Open the Freedrum Sensorware app on your iOS, Android, or Windows device.  Turn on your Freedrum Sensors. Select the appropriate sensor from the list in the app that you want to update.  Scroll to the bottom of the screen and select "Check for Sensorware Update". The app will update the sensor. This will take about 60 to 90 seconds. Do not turn off the sensor or close the app during this time to avoid corrupting the data.  Repeat this process for all sensors. Once updated, restart the Sensorware application to reconnect to the updated sensors.
