OTA Uploader vs HelloBlue

OTA updater

HelloBlue turns your iPhone or iPad into a Bluetooth Low Energy (BLE) debugging tool. Scan nearby devices, connect in a tap, explore every service and characteristic, send data, and watch the traffic live, all in one clean app. Built for firmware engineers, IoT developers, testers, and hardware makers who need to inspect and talk to BLE devices quickly. KEY FEATURES - Scan and connect Discover nearby BLE devices with live signal strength (RSSI). Search by name or UUID, sort by name or signal, rename devices, and reconnect to recent devices automatically. - Services and characteristics Browse every GATT service and characteristic. Read values as hex and text, write data, and subscribe to notifications. Give services and characteristics names that make sense to you. - Send data your way Send in Hex, String, or JSON. Save frequently used commands as quick texts and resend them with one tap. - Live operation logs Watch reads, writes, notifications, and errors stream in real time from any screen. Filter entries and turn auto-scroll on or off. - Session history Every session and automation run is saved. Review past logs, rename them, export them to share with your team, or delete what you no longer need. - Automation workflows Chain connect, write, delay, and loop steps into reusable flows. Set message intervals and repeat counts, and choose whether each step stops or continues on failure. - Location history HelloBlue records where a device was each time it connects, making it easier to find again. - iPhone and iPad Works on both, with layouts designed for each screen. Bluetooth must be turned on, and HelloBlue needs Bluetooth permission to scan and connect. Location history requires location permission. Some features depend on the services and characteristics your device provides.
