BBPOS Chipper 2X BT setup

Learn to use the BBPOS Chipper 2X BT mobile card reader with Stripe Terminal.

The BBPOS Chipper 2X BT is a handheld reader for use with mobile applications. It uses Bluetooth Low Energy (LE) to connect to the Stripe Terminal SDK on a mobile device.

This reader is compatible with iOS and Android SDKs. To view the reader’s parts and features, see the BBPOS Chipper 2X BT product sheet.

Turning the reader on and off

To turn on the BBPOS Chipper 2X BT, press and release the power button. The status light turns on to indicate power. The reader waits for a Bluetooth connection for five minutes before turning off.

When the reader is connected to a device running your app, its status light shines steady blue. If inactive for more than 30 seconds, it enters standby mode to conserve power, and the status light begins flashing at 5-second intervals. The reader stays connected to your iOS or Android device while in standby and automatically exits standby mode when you resume activity.

The reader automatically turns off after 10 hours of inactivity. To turn the reader off manually, press and hold the power button until the status light goes out. You don’t need to turn off the reader to conserve power.

Status light

Whenever the BBPOS Chipper 2X BT is turned on, the LED located beside the power button shows the reader’s current status.

Flashing blue every second The reader is on and ready to connect to a device. (Will turn off after 5 min.)

Charging the reader

To charge the BBPOS Chipper 2X BT, use the included micro USB cable. The USB port does not work for connecting the reader to a device—it’s only for charging.

Updating reader software

You must support updating the BBPOS Chipper 2X BT from your application. The reader cannot update itself. These updates include regional configurations that keep you up to date with card network and issuer requirements, as well as potential security updates. Read about reader software updates for details.

In your app, notify the user that an update is available, display whether the update is required, and provide a button to continue with the update. Failing to install a required update could prevent a reader from accepting payments.

  1. Use the checkForUpdate method to check for available updates

  2. If an update is available, your app’s callback receives a ReaderSoftwareUpdate object containing update details, including an estimate of how long the update will take. In your app, notify users that an update is available, and display a prompt to continue with the update. Include the time estimate in your app’s UI.

  3. To proceed with the update, call installUpdate with the ReaderSoftwareUpdate object. As the update proceeds, block the user from leaving the page in your app, and instruct the user to keep the reader in range and powered on until the update is complete. We recommend also providing your user with a visual indicator of the update’s progress.

To test your app’s ability to install reader software updates, use the simulated reader. When you call the checkForUpdate and installUpdate methods with your application connected to a simulated reader, the SDK responds with the same events your application would receive when updating a physical reader.

See a sample implementation in our iOS or Android example apps.
