20 BLUETOOTH SIG APPROVALS
20.1 Subsystem Combinations
This section covers the procedure for generating a new EPL (End Product Listing) on the Bluetooth SIG
website. In the instance of subsystems, a member can combine two or more subsystems to create a
complete Bluetooth end product.

20.1.1 Assumptions
This procedure assumes that the member is simply combining two subsystems to create a complete end
product. This is achieved by using the EPL interface on the Bluetooth SIG website. The following diagram
shows the basic subsystem combination of a controller and host subsystem. The controller provides the
RF/BB/LM and HCI layers, with the host providing L2CAP, SDP, GAP, RFCOMM/SPP, and any other
specific protocols and profiles existing in the host subsystem listing.
The following link provides an overview of the EPL system:

For a detailed procedure of how to make an EPL entry, please refer to the following SIG document:
https://www.bluetooth.org/docman/handlers/DownloadDoc.ashx?doc_id=71880
In the case of the Laird and Cambridge Consultants Limited subsystem combination, please search for
QDID B016072 in step 4 and then ‘Create New EPL’ as per step 5. Under step 7, enter QDID B017578 in
the box ‘Link additional QDLs’.
