Bolt - Getting Started

The Bolt is Digital Matter’s new compact, plug and play OBDII tracking device. It is available in 2G or 4G Cat-M1/Nb-IoT versions.


The device requires next to no installation, drawing its power from a vehicle’s OBDII port. (Note the Bolt will not read OBDII diagnostic data) It is designed to provide extremely cost-effective tracking with all the quality and support of a Digital Matter product. It includes the latest GPS and cellular technology to give excellent performance at an entry level price.

In the Box

You'll get a compact box containing the Bolt with unsealed housing inside a sleeve and a backing sticker with an LED hole.

Setting it up

Sim Card

The Bolt uses a Nano SIM (4FF)

  1. Remove the board from the housing, the board will be sitting inside the bottom housing and can slide out smoothly without detaching any screws or clips.
  2. Orientate the Nano SIM with the contacts facing down and the keyed corner towards the board.
  3. Slide the SIM into the SIM holder


Make sure once you're online, to declare your APN in the Admin parameters to ensure if you lose the network connection the device knows where to re-connect, and doesnt take time and battery life scanning through all known frequencies

Close the Housing

The housing clips together and does not need screws, once it is sealed, it will snap firmly shut – Re-opening of the housing will often result in the breakage of the clips. Digital Matter can supply a replacement if you damage the unit by opening it.

Plug into Vehicle

The Blue LED will flash at 1Hz if it is getting powered. You can find where your vehicle’s OBDII point is by researching the make and model online


Once the battery is connected, the internal LED will come on and flash blue and the device will do the following:

  1. Connect to the server: If the SIM card works, the device will connect to the OEM Server. It will attempt to download any firmware and parameter updates and fetch fresh GPS aiding data.
  2. Get a GPS Fix: the device will attempt to get a GPS fix. Speed this up by moving to an area with good GPS signal.
  3. Reconnect to the server: The device will attempt to connect again to upload the result of the GPS Fix.
  4. Stop flashing: once complete, the LED will stop flashing. If the device does not complete these steps in 10 minutes, it will go to sleep and try again on the next heartbeat or the next trip start.

OEMServer Installer

Go to for ease of testing

If the LED flashes but the Bolt does not connect, check the SIM is in the holder correctly and check that the SIM is working. 

Default Settings

The Bolt will operate with default settings out of the box. These can be changed using the OEM Admin interface. The defaults include:

  • Hourly Heartbeats: the device will log a heartbeat record, connect to the server, and refresh its GPS data every 60 minutes.
  • Logging: The device is set to log a record every 60 seconds or 500m of distance travelled, whichever comes first.
  • Heading Changes: The Device will also log a record when the heading change of is detected and will track when the vehicle corners.
  • Emulated Ignition: By default, the Bolt will track a trip if only if the ignition of the vehicle is activated. A trip will commence recording if the vehicle has moved more than 150m from its starting position. The Trip will automatically end if device has been stationary for 6 minutes. The device will upload at the beginning and end of a trip.
