Blink - Troubleshooting Guide

This document is a supplement to the user manuals for our Blink time lapse controller product. The manuals should be read in conjunction with the troubleshooting Q & A below.

Before consulting the troubleshooting guide, make sure that your GoPro and Blink are running the most recent firmware available and you are using an SD card that has a minimum read and write speed of 30MB/s (U3 rating). Our website has a link to an SD card speed tester to determine if your SD card has the required speeds for reliable use with the GoPro cameras.

 

Troubleshooting Questions

Blink WiFi can be turned on via the wired remote that ships with the product. Plug the remote into the 2.5mm jack on the side of Blink (on the opposite side from the mini USB port. It is on the right hand side when look at Blink from the back of the camera).

 

Hold down the wired remote button for 3 seconds - you will see the LED on the back of Blink flash cyan three times to indicate WiFi signal has been enabled. The LED will continue to flash blue every 5 seconds while WiFi is active. Blink WiFi can be turned off manually by pressing the wired remote button again for 3 seconds and the LED will flash cyan twice to indicate WiFi is turned off. WiFi will also automatically turn off after 15 minutes.

Why does Blink's WiFi not activate when I use the remote?

Blink requires more power when the WiFi signal is active. If Blink's LED flashes purple, this is typically an indication of insufficient power available to activate the WiFi signal. Make sure to use a fully charged battery or have an external power source plugged into Blink's USB port when activating WiFi. Once the new shooting schedule has been programmed, WiFi is no longer needed for regular operation and the system can continue to run off a lower charged battery.

I have Blink powered from an external battery pack. Why does the shooting schedule only last for one day when I still have power in the battery pack?

Most of the batteries on the market, including ours, have an automatic power saving feature which turns off the battery if the battery is not constantly supplying power to a device. If the GoPro is powered off for more than a few minutes between triggers, the external battery might automatically shutdown due to inactivity. However, our V15 and V44 battery packs have two modes of operation, the standard Automatic Off mode and an Always On mode. The Always On mode is important to prevent the battery from automatically turning off when insufficient current is being drawn due to the camera being powered off by Blink to conserve power.

If using our V15 or V44 battery, make sure to activate the Always On feature. It is easiest to determine the battery's operating mode when the battery is disconnected and neither charging or supplying power. When in Always On mode, if you double tap the power button a few times, the LED should continue to stay lit. If the LED goes dark between every other double press, you are not in Always On mode. To switch modes, hold down the power button for six seconds. If the charge indicator flashes 3 times and stays lit for a second or two, you are now in Always On mode. If the charge indicator flashes 3 times and then goes dark, you are now in Automatic Off mode. If you are not in the desired mode. Press the button again for 6 seconds to change modes.

Blink is turning the GoPro on at the scheduled time, but why is the shutter not being triggered?

Make sure you do not have have the "Enable Scripting" checkbox enabled at the top of the UI. If this checkbox is enabled, Blink will only turn the camera on at the scheduled time with no further function since it expects a script on the camera's SD card to control the functionality once the camera has been turned on. If you are not using scripts, make sure to disable this checkbox for regular operation.

Why does my device not stay connected to Blink's WiFi signal?

Some phones and computers have a WiFi setting that will automatically connect to a known WiFi network with the strongest internet signal rather than staying connected to Blink. Since connecting to Blink's WiFi network does not provide external internet access, some devices will not stay connected. You might need to temporarily deactivate this setting or remove other known networks in the area for the period required to set up the new shooting schedule of Blink.

Why is my continuous video footage being split into multiple files?

The splitting of the files into sections is called "chaptering", and the final video clip can be joined back into a single file by using GoPro Studio, Adobe, or another video editing software. The chaptering a recording into multiple files reduces the chance of losing the entire footage if the power is suddenly lost, the camera crashes, or another issue causes the last recorded file to become corrupted to the point where it cannot be repaired by the camera. The length of each file is determined by the recording mode used but has a maximum file size of 4GB per file. This is because the GoPro camera saves files to the SD card in the FAT32 format which has a maximum file size of 4GB. The GoPro requires that the SD card has a FAT32 format, or exFAT for 64GB or larger cards, however, the file will still be saved in the FAT32 format that has a maximum file size limited to 4GB. 

Blink firmware will be released periodically with new features and/or bug fixes. Head over to this page for detailed instructions.

When updating the Blink firmware with the OTG cable, make sure to have Blink unplugged from the GoPro camera while having Blink and the flash drive connected to the OTG cable before the male USB-A end is plugged into a 5V DC source. The USB flash drive must be using the FAT file format to be able to perform the firmware update.
