Firmware updates add features to Marty V2 and improve how the robot works. Use the Marty Web Updater to install them over USB from a computer.
Firmware updates over Bluetooth (BLE) are no longer supported. You need a USB connection to a computer to update Marty.
In the current Robotical app, open Robot settings using the robot-and-gear icon at the bottom left to see Marty's Current Version. The Update Your Marty button opens the web updater; it does not install an update over Bluetooth. If you are using an iPad or phone, open the updater on a computer instead.
Updating over USB
Use Google Chrome on a laptop, desktop or Chromebook with an internet connection. Your USB cable must support data transfer, not just charging. Disconnect any other app or browser tab using Marty's USB serial connection before starting.
1. Connect Marty and open the updater
Connect Marty to your computer using the USB cable, then open the Marty Web Updater.
2. Start the update
Click Start Update. In the browser's serial-port chooser, select Marty's USB device, then click Connect. Its name may contain CP2102N, USB Serial or CH340, depending on the hardware and driver.
If no device appears, check that the USB cable supports data and see the Driver Installation section below.
3. Let all update stages finish
Keep the USB cable connected and the updater page open while it updates Marty, including any servo and sensor updates. Marty may restart during the process.
If the updater reports that the main robot update is complete but the servo and sensor update still needs to run, choose Finish Update (or Finish update in the message). If a recovery message offers Update Servos and Sensors, use that button to finish the remaining updates. Select Marty's serial port again if prompted.
If colour-sensor calibration is requested, follow the on-screen instructions before continuing.
Wait until the updater shows Firmware update successful at 100%. You can then reconnect to Marty in the Robotical app and check the current version in Robot settings.
