New Features
Bluetooth can be used to configure the JuiceBox WLAN interface in compatible devices using the JuiceConfigure app, for iOS or Android.
Local configuration of maximum current level to reduce the maximum JuiceBox output current can be performed via JuiceConfigure through either the Wi-Fi or the Bluetooth interfaces.
Resolved Issues
NTP time synchronization was not frequent enough, resulting in incorrect start and stop charging times when the charger is offline, as well as incorrect 15-minute interval data reporting. Frequency increased to once every 24 hours
In certain situations, the crystal oscillator may become an unreliable time source. This firmware overcomes this by using the WGM160P internal oscillator as the time source when the crystal oscillator is found to be incorrect. Checks performed every 1 minute
Known Issues
Power measurements across two phases (for example, on Isolated Terra power grids) are not reported correctly.
Known Limitations
European-style over-current protection is not enabled on JuiceBoxes sold in North America. Over-current protection is not required by US/North American standards.
