ICPROX-OTABRIDGE
The ICPROX-OTABRIDGE is the USB transmitter stick that delivers firmware updates and initial provisioning over the air to ICPROX-Tags and other radino40 devices. It plugs into a PC's USB port and transmits on the 2.4 GHz channel every device listens on while in update mode — no cable at the device, no opening of enclosures, tags can even stay in their charging cradles.
Operation is entirely browser-based (Chrome/Edge, Web Serial) — no software installation. Transfers are AES-256 encrypted and checksummed; a full firmware image is on air within seconds.

Getting started
- Plug the stick into a USB port — it enumerates as a serial port, the green LED pulses.
- Open the update tool (HTML page) in Chrome or Edge and connect to the stick's COM port.
- Select the firmware package (ZIP) supplied by In-Circuit and enter the target device's serial number.
- Restart the target device (e.g. briefly dock a tag in its charging cradle) — it listens for updates during start-up.
- Start the update and wait until the tool reports completion; the device then boots the new firmware.
Full instructions, LED meanings and troubleshooting are in the manual.
