I just released v7.5-rc1 for the latest ESP32-based controllers. This one is mostly about reliability and cleanup rather than big new features. Assuming further testing goes well, this will become the full v7.5 release.
Smarter BMS temp probe handling
Battery temp probes now behave much better when one disconnects or reports bad data. The firmware is better at ignoring temporary bad readings without throwing unnecessary alerts, while still catching real issues.
BLE cleanup
We also removed the old legacy BLE telemetry path and standardized on the newer packed telemetry format, which simplifies the firmware and helps prepare for future work.
If you want to try it now, you can update through the SP140 configurator, but for the moment, you’ll need to enable the prerelease firmware toggle in the updater tool.
Looking ahead
Because of some larger architecture changes already underway, we’ve decided the next major release with app support will be 8.0 rather than 7.x. v7.5 helps set the stage for that.
