Technical Questions

How do I update OpenGarage firmware?

Compiled firmwares are all released on OpenGarage Github repository. They may be found here.
Before proceeding, note that once a new firmware is uploaded, the log will be erased, so keep a copy of the log if you need to retain it.

  • Use the web interface to update firmware (click the ‘Update’ button at the bottom of the homepage or on the Options page).
  • If the built-in web interface is not responding, perform a factory reset (i.e. pressing the button for 5 seconds or more), then follow the setup steps but leave the cloud token empty (to avoid any potential Blynk connection issues). Once the firmware is updated, go to the Options page and put in the Blynk token, make sure the Accessibility is set to ‘Direct IP + Cloud’.
  • If neither of the above work, you can use a USB cable to flash a new firmware (see instructions below).

After updating firmware, check the bottom of the homepage and make sure the firmware version is correct.

 

How do I reflash the firmware using a microUSB cable?

In the event that the controller cannot boot correctly (such that you can’t have access to over-the-air update), you can reflash the firmware via a microUSB cable.

Step 1: Driver. Depending on your operating system:

  • Windows: driver is not required, except Windows 7 64-bit and Windows XP (install CH340 Windows driver).
  • Mac OSX: install CH340 Mac driver, and reboot.
  • Linux: driver is not required, but you need to run all following commands as root or with ‘sudo’.

Step 2: Bootloading mode and serial port.
Let the device enter bootloading mode. To do so, get a microUSB cable, plug the smaller end to the device’s USB port, then press and hold the pushbutton while plugging the cable’s other end to your computer. The LED light should stay on constantly, and you should not hear any buzzer sound. If not, unplug the USB cable and redo this step.

Next, the device should appear as a serial port and you need to find out the serial port name:

  • Windows: the serial port name is COM? where ? is a number. You can find out the port name in the notification area, or in Device Manager — Serial Port.
  • Mac OSX: the serial port name is /dev/tty.wchusbserial? where ? is a number. You can find out the port name by running ls /dev/tty.wch* in Terminal (i.e. command line).
  • Linux: the serial port name is /dev/ttyUSB? where ? is a number. Run ls /dev/ttyUSB* in command line to find out.

Step 3: Reflash firmware.

Download the OpenGarage reflash package and unzip it. The package includes esptool, nodemcu firmware, and OpenGarage firmware. Open a Terminal (i.e. command line window), cd to the folder where you unzipped the package. Depending on your operating system, run the following command (assuming the device is in bootloading mode):

  • Windows: esptool.exe -cd ck -cb 230400 -cp COM? -ca 0x00000 -cf nodemcu.bin where COM? is the serial port name you found in Step 2 above.
  • Mac OSX: ./esptool_mac -cd ck -cb 230400 -cp /dev/tty.wchusbserial? -ca 0x00000 -cf nodemcu.bin where wchusbserial? is the serial port name you found in Step 2 above.
  • Linux: sudo ./esptool_lin32 -cd ck -cb 230400 -cp /dev/ttyUSB? -ca 0x00000 -cf nodemcu.bin where ttyUSB? is the serial port name. If you use Linux 64-bit, use sudo ./esptool_lin64 instead.

If you encounter any error, check if the device is in bootloading mode. Repeat Step 2 to enter bootloading mode before flashing.

Finally, once the nodemcu firmware is flashed, re-enter bootloading mode (Step 2) and run the above esptool flashing command again, except replacing nodemcu.bin at the end with og_1.0.4.bin. This completes the firmware reflashing.

 

How do I restore settings to factory default?

At any point, you can press and hold the pushbutton for 5 seconds or more until the LED stays on, then release the button to reset the controller back to factory default.
