Firmware v2026-09-08a-ble-reliabilitySeptember 8, 2026
Faster, more reliable BLE connections
This release improves controller discovery and connection stability, especially when the controller is installed inside a metal espresso-machine enclosure.
- Controller release builds now run the ESP32-S3 at its full 240 MHz clock speed.
- BLE advertising now uses +9 dBm power and a faster 100–150 ms interval for quicker, more reliable discovery.
- A connected scale remains available for up to 10 minutes after the mobile app closes or moves to the background.
- Shots and scale calibration continue to prevent an in-use scale from being disconnected.
- Telemetry pacing, acknowledged profile transfers, and bounded scale scanning remain in place to prevent BLE congestion.
- The matching mobile app keeps Android BLE at high priority while foregrounded and restores balanced priority in the background.
- Matching update and full-install images are available for both production and beta-v1 controllers.
