How do I update Pixelblaze?

If you have a recent version of Pixelblaze firmware (v2.18 or above, or any V3), you can update right from settings as long as your Pixelblaze is connected to the internet.

If you can’t connect your Pixelblaze to the internet, you can upload a firmware update file using the /update URL. For example if in AP mode, the full URL would be http://192.168.4.1/update

If you need an update file please contact wizard@electromage.com with information about your model (V2, V3 Standard, V3 Pico).

For older versions of V2 (v2.17 or older), keep reading.

WARNING: Instructions below are for V2 only, and only if you have firmware older than v2.18. DO NOT USE THIS WITH V3

To update Pixelblaze’s firmware older than v2.18, first download and unzip this file:

http://app.bhencke.com/pbupdates/latest.zip

To prevent drive-by firmware updates, Pixelblaze versions before v2.18 can only be updated in AP mode. You might need to put it in WIFI setup mode, give it an AP name+pass, then do the update. To put it in WiFi setup mode, hold the button (or connect one to GP0 and GND for older hardware) for 5 seconds after powering PB. Then configure it in AP mode (it won’t update in setup mode).

Connect to PB’s AP network. For macs & linux, open a terminal and cd to the unzipped directory. Then run the ./update.sh. For windows, run update.bat. Two files will be uploaded, and you should see some 200 OK output from curl.

If anything looks weird or you run in to trouble, try to capture the output and let me know and we’ll get it sorted out.

v2.18 and newer now supports secure online firmware update. Once you install this version, you can then use the update function in settings to check for and update to the latest version.

“v2.18 and above now supports secure online firmware update. Once you install this version, you can then use the update function in settings to check for and update to the latest version.”

Do you mean 2.17 ? Or should I wait for 2.18 so I only have to do it once

I need to rephrase the post!

The latest version as of this moment is v2.21. if you have v2.17 or older, then the update instructions above apply. If you follow them, you’ll have v2.21. Anything newer than v2.17 supports the easier method already.

If your Pixelblaze shipped in the last few weeks, you might have the version that supports the easier method.

I had to do this again today with an old Pixelblaze (hardware v2.7) board I had in inventory - I’m a stickler for step by step documentation so perhaps this helps someone else get all the way to the latest firmware…

Start by downloading the .zip provided by @wizard above and save it on your laptop (or desktop with WiFi) you will need this file, but won’t have Internet access when your connected to the PB in AP mode, so get it now before starting these steps…

  1. hold down the little button for 5 seconds, then release (PB resets and reboots)
  2. connect to the Pixelblaze_XXXXX SSID
  3. visit http://192.168.4.1 in a browser (I used firefox)
  4. press the blue button “Configure AP” and give it a temporary SSID and password (I used: PBupdate with pass: 12345678)
  5. connect to the PBupdate SSID
  6. extract the .zip provided by @wizard above, and assuming you’re running Windows double-click on update.bat (do not run as admin)
  7. wait for the batch file to end with >pause
    Press any key to continue…

– at this point you’re at firmware v2.21, but that’s not the latest, the PB needs Internet by connecting to your WiFi before the Update option shows up under Settings –

  1. hold down the little button for 5 seconds, then release (PB resets and reboots)
  2. connect to the Pixelblaze_XXXXX SSID
  3. visit http://192.168.4.1 in a browser (I used firefox)
  4. click the blue button “Configure WiFi” and connect to your WiFi with working Internet
  5. BP reboots and get’s an IP from your router/DHCP server, look in your DHCP table to find the IP it got, or scan the entire network with software such as “Advanced IP Scanner” to find it
  6. visit http://your_pixelblaze_IP in a browser (I used firefox)
  7. go to Settings, at the bottom pick the green button “Check for Update” followed by “Perform Update and Restart”

– after a short while the browser should refresh to the same IP, at the time of this post, my PB gets firmware v2.23 –
