What's New in BLESerial nRF
3.9.0
September 16, 2026
This Bluetooth serial UART monitor app is designed to communicate with the Nordic UART Service, as used on nRF52 modules and in Arduino, Raspberry Pi Pico and ESP32 projects. Why 3.9? BLE Serial nRF52 and BLE Serial Pro are now built from the same code and share one version number, so this update jumps from 1.5.0 straight to 3.9.0. What’s new: - Dark mode support, with a Light / Dark / Automatic switch in App Settings. - Export Plain Text now really exports plain text. - New system icons throughout.
