The corresponding programs may fail to run if a firmware version is too low.
If the mBlock 5 app does not support firmware update of a device, it is recommended that you use a USB cable to connect the device to computer and update the firmware of the device through mBlock 5 on the computer or web (www.mblock.cc).
Update Firmware Through mBlock 5 on the Computer or Web
(1) Use a USB cable to connect your device to the computer.
(2) Open mBlock 5 and connect the device. (You need to start mLink first if you use mBlock 5 on the web.)
(3) Click Setting, and then click Firmware Update. Click Updates in the dialog box that appears.
Update Firmware Through the mBlock 5 App
When a device is connected to the mBlock 5 app through Bluetooth, mBlock 5 automatically detects the firmware version of the device. If it identifies that the firmware is not the latest one, it displays the Firmware Update button after the device is connected.
Click Firmware Update, and then enter a Wi-Fi name and password to access the Internet. After Wi-Fi connection is successful, the firmware of the device is automatically updated.
