Marty can be updated over USB from computer or Bluetooth (BLE) using our Android/iOS app.

We'll release updates periodically, which will enable new features on Marty or improve functionality.

===== Updating over USB =====

You can also update your Marty with our **Web Updater **[[https://updates.robotical.io/web-updater/|here]]. This updater is faster than over Bluetooth so we would recommend using the web updater if you have lots of Marty's to update.

To update your Marty:

**1. Connect Marty to your computer using a USB cable. Click the "Update Your Marty" button.**

After you click you will see a pop-up saying this program "wants to connect to a serial port." If one of the options says "CP2102N" or "USB Serial" then please select that one.

Once you select update, the app will download the most recent Marty firmware, and then upload it to your Marty. This upload process starts at about 10% of the update, and may appear to go very slowly.  __The full update process may take 10 minutes, don't be worried if it looks like it's slow__

After reaching 90%, your Marty will restart and begin running the new firmware. The app will check the update has been successful, and then begin running any additional updates - e.g. to servos or sensors. If updates are required this may also take a couple of minutes - be patient!

If all goes well, you'll see the message that all updates were successful! If something doesn't work, please run the update again
