Upgrading the XRS2i/SRS2i Bluetooth firmware (automatic method)

Upgrade the firmware on your XRS2i or SRS2i EID stick reader for improved Bluetooth connectivity

Updated over a week ago

In early 2025, we released a firmware upgrade for the XRS2i and SRS2i EID stick readers. This firmware upgrade improves Bluetooth performance, providing a more reliable connection between the EID stick reader and other devices. There are a number of steps required to complete this upgrade.

📝 This is a one-off upgrade. Once you have performed the steps in this article, you will not need to repeat this procedure again.

📝 This article describes the automatic method of performing this upgrade. This is the normal, recommended method. However, if you have been supplied with the upgrade files, you can use the manual method.

Before you start

Before you begin the upgrade process:

  1. Update Data Link PC software. It must be version 5.19.0.1 or above. Lower versions do not support the Bluetooth upgrade.

  2. Check your PC to make sure it has a Bluetooth. If not, we recommend purchasing a Bluetooth 5.0 dongle and skipping to step 4. If you decide not to proceed with the upgrade, see What if I decide not to upgrade the Bluetooth firmware on my XS2i/SRS2i EID stick reader?

  3. If your PC has Bluetooth, check that it has Bluetooth LMP version 6.1 or above. See the Microsoft article here for information on how to do this. If your Bluetooth LPM version is 6.0 or below, we recommend purchasing a Bluetooth 5.0 dongle. This will have LPM version 9.0. If you decide not to proceed with the upgrade, see What if I decide not to upgrade the Bluetooth firmware on my XS2i/SRS2i EID stick reader?
    📝 Lower versions of Bluetooth LPM will not allow you to perform the firmware upgrade on the EID stick reader. You must ensure your LPM version is 6.1 or above before proceeding.

  4. Check the Bluetooth settings on your XRS2i/SRS2i EID stick reader.
    The Bluetooth Connect Mode and Output settings must be set to default.

    (a) Go to Settings / Bluetooth / Advanced.

    (b) Set Connect Mode and Output to [Default] (XRS2i only):

  5. Check the Bluetooth settings on your PC.
    (a) On your PC, search for 'Bluetooth and other devices settings':


    (b) Check that Bluetooth is ON and check that the XRS2i/SRS2i EID stick reader is not connected (not paired):


💡 If the stick reader is connected (paired), disconnect (unpair) it. To do this, click on XRS2i/SRS2i ... and select Remove Device:
