USB BLE receiver: TPMS data on the screen you already have A BPU301 USB BLE receiver pulls pressure, temperature and battery status from our BLE sensors and hands it to your Android head unit over a virtual serial port. No receiver box to mount, no wiring to the cab - it plugs into the USB port you already have.

What the BPU301 actually is

The BPU301 is our BLE receiver board in a small USB housing: the BPU300 bare board, a USB-to-UART stage, and a standard public-mould USB enclosure. It pairs with our BPU100 / BPU110 / BPU120 sensors and outputs their data as a serial stream over USB.

Your head unit, tablet or app reads that stream and decides what to show. We do not lock the presentation, and the pairing list is not tied to one particular screen. If you give us the sensor IDs, we pair the receiver to your sensors at the factory, so the unit arrives already matched to the set that ships with it.

Radio is 2.4 GHz BLE 5.1, the same platform as the rest of the GZ MOTO range. One USB port is all the hardware needs: no external power supply, no CAN wiring, no separate display. Wheel positions follow the same architecture as our other receivers - up to 256 per receiver, so a multi-axle trailer is a software question rather than a second box.

Who it is for

• Android head-unit manufacturers who want a tyre-pressure screen without building and stocking a full TPMS kit.
• Fleet and workshop apps running on an Android tablet or a fixed display.
• Any device with a USB host port that needs pressure data from a sensor - it works with an existing Android app; the app is the customer's, not ours.

What you supply, what we supply

We supply the USB receiver (paired to your sensors at the factory if you send us the IDs), plus the serial protocol document, which is open and documented. You supply the app or the screen, and whatever user interface you want on top of it. We can supply a reference Android app (APK, not published on any app store) for evaluation only.

Customisation

Firmware key mapping, output format and pairing behaviour can be adapted to your app; that is quoted per project. The receiver is a BLE product, so the model number stays in the BPU3xx range - none of the 433.92 MHz receiver names apply to it.

What we do not claim

We do not publish a list of certified host devices, and we do not claim that every Android head unit on the market will accept the virtual serial port out of the box. Send us the head-unit model and the Android version you are working with, and we will answer for that combination rather than for Android in general.
