Latest Stable Release

Latest Beta Release

Access the latest features via our beta releases. Note these releases potentially have bugs and are not fully supported. But if you find a bug, please let us know at - that's one of the reasons we release beta firmware. Download the latest stable release above if you are not keen on testing the new features.

  • No beta releases currently available.

If your Blink does not match the latest Blink firmware available, download the latest stable or beta Blink firmware by clicking one of the links above. Then follow the steps outlined below or in the Blink User Manual to update your Blink.

If your Blink is deployed out in the field, we have a list of the changes between firmware versions at the bottom of the page that can be used to determine if a new update requires retrieving the camera.

How to update Blink firmware

  1. Download the blink_update.bin update file and transfer it to the root folder of a USB flash drive. The USB flash drive must be using the FAT32 file saving format* (typically the default format for USB drives 32GB or less).
  2. Connect the flash drive to one end of the USB OTG Cable and the other end to Blink. Blink should not be connected to the GoPro camera during the firmware update process.
  3. Finally connect the last end of the cable to a power source such as a mobile phone USB charger/USB battery pack/Laptop, etc.
  4. Blink will start the update immediately. During the firmware update, the LED will follow the pattern below.
    1. Magenta flash continuously every 0.25 seconds: Firmware from the USB flash drive is transferring to Blink storage.
    2. Green flash twice: Firmware successfully stored.
    3. Magenta flash continuously every 0.25 seconds: Firmware from internal Blink storage is installing.
    4. Green flash three times: Firmware successfully installed.
    • Any number of Red LED flashes indicates an error has occurred.
      When updating the firmware, if the LED flashes red twice when power is connected, this is an indication that Blink cannot read the file from the USB drive. Blink will not be able to read the file if the USB drive is
      not using the FAT32 format or theupdate filename has been changed from blink_update.bin
  1. Once the LED flashes complete, turn Blink's WiFi on with the remote and connect to the Blink UI page to check the top right corner and verify the update.

  2. After a firmware update, ensure to click the CLEAR ALL button to clear all previously saved information. After clicking the clear button, the status bar should display No upcoming schedules and all schedules should be displayed as disabled. If schedules are still displayed as enabled (highlighted blue), refresh your web browser before re-programming your desired schedules.

    If this button is not used to clear and disable all schedules, information saved before the firmware update, but no longer displayed, may interfere with any newly programmed shooting schedules.

*Note:The USB flash drive must be using the FAT32 format and if the update filename has been changed, Blink will not recognize the file. For example, "blink_update(1).bin" or "blink_update.bin.txt" will not be recognized. Blink does not support partitioned drives or other formats. The FAT32 file saving format is typically the default format for most USB flash drives that are 32GB or less. Large capacity flash drives might be using the exFAT format which is not compatible with Blink. If you are using a MAC, the following link explains how to format a USB flash drive to FAT32.
