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…
- hold down the little button for 5 seconds, then release (PB resets and reboots)
- connect to the Pixelblaze_XXXXX SSID
- visit http://192.168.4.1 in a browser (I used firefox)
- press the blue button “Configure AP” and give it a temporary SSID and password (I used: PBupdate with pass: 12345678)
- connect to the PBupdate SSID
- extract the .zip provided by @wizard above, and assuming you’re running Windows double-click on update.bat (do not run as admin)
- 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 –
- hold down the little button for 5 seconds, then release (PB resets and reboots)
- connect to the Pixelblaze_XXXXX SSID
- visit http://192.168.4.1 in a browser (I used firefox)
- click the blue button “Configure WiFi” and connect to your WiFi with working Internet
- 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
- visit http://your_pixelblaze_IP in a browser (I used firefox)
- 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 –
