RESOLVED :Smartshunt and smart solar Bluetooth beta firmware 2.33 fails to install.

6a92f710-2823-4bc5-9ec6-33428f0980be.pngA new beta came out today that includes smartshunt 2.33. It failed during the upgrade. I now cannot connect. I get the message to install the firmware. Tried the officially released version and it fails also. the smartshunt is connected to my color control and appears to be reporting fine. I just can’t connect to it via Bluetooth without getting the message to upgrade the firmware.

Anyone know where I can obtain the Bluetooth firmware file? I logged into the Pro section but it doesn’t have any Bluetooth files.


Resolved: I placed my device within 3 inches of the mppt and then the SmartShunt. The Bluetooth firmware updated successfully. Prior attempts were about 3 feet away. Go figure.

I had the same issue with the iOS beta. The update continued to fail after reinstalling the app, removing the Bluetooth device and disconnecting / reconnecting the BMV.


I downloaded the MacOS beta and tried the update here. It worked! Now the iOS app can connect as normal.

Try doing the update here on the vrm you could also manually download the firmware and use this to install that version. Dont know if this will fix the issue but it will do away with the bluetooth part of the update

Getting the same error with a SmartSolar 250/100.


Tried bring the iOS device closer (1 inch!), no good.

Tried OSX version, no good.

Updating the Bluetooth Firmware not offered as an option in VRM, so, no good.

Guess we can at least definitively say that v 2.33 Bluetooth update (or at least the update process!) is FUBAR.
