BLHeli_32 is a free Android application developed by Steffen Skaug in the Utilities & Tools category. It is designed to configure BLHeli_32 Electronic Speed Controllers (ESCs) and supports various USB connections to ESCs. The app requires USB host mode (OTG) support on the device.

The app supports USB connections to ESC(s) via a USB connected flight controller (FC) that supports BLHeli_32 passthrough, a USB adapter with CP210x, FT232 or CH34x USB to UART device, and a USB connected Arduino programmed for BLHeli bootloader. Additionally, it supports connection to FC via SpeedyBee Bluetooth devices. BLHeli_32 is a useful tool for users who need to configure ESCs and provides a simple and easy-to-use interface.
