The services are enabledvia Command API and serviced in the same manner.Each service manages “Characteristics” which as datavalues are declared and defined by Bluetooth. The val-ues for ea ch characteristic are ca ched in modulesmemory and can be read by another Bluetooth device,such Smartphone acting in Central role. The values ofevery Characteristic are updated via Command APIover UART. 7.1 Public and Private ServicesThe RN4020 provided the ability to cre ate customerservices. If the services a re supported on both endpoints of a Bluetooth Low Energy connection, such asCentral and Peripheral devices, data can beexchanged. For example, two RN4020 modules candefine a custom (private) service with its own u niquecharacteristics. Data can be exchanged easily viaCommand API.Private services are not registered with the BluetoothSIG, and therefore not in teroperable with other Blu e-tooth Low Energy device s, unless the device imple-ments the private service. An example of a bui lt-inprivate service is Microchip Streaming Data service.Refer to “ RN4020 Command Reference”, docxxx-xxxxxx, and Application Note AN-xxxxxx for an exam-ple on h ow to crea te a custom service using theRN4020.7.2 PCB AntennaThe PCB antenna is fabricated on the top copper layerand covered in solder mask. T he layers below theantenna do not have copper trace. It is recommendedthat the module is mounted on the edge of the hostPCB. It is permitted for PCB material to be below theantenna structure of the module as long as no coppertraces or planes are on the host PCB in that area.

Modular approval allows theend user to integrate the R N4020 module into a fin-ished product without obtaining subsequent and sepa-rate FCC approvals for i ntentional radiation, providedno changes or modifications are made to the modul ecircuitry. Changes or modi fications could void theuser’s authority to op erate the equipment. The enduser must comply with all of the instructions providedby the Grantee, which indicate installation and/or oper-ating conditions necessary for compliance.The finished product is required to comply with all appli-cable FCC equipment authorizations regulations,requirements and equipment functions not associatedwith the transmitter module portion. For example, com-pliance must be demonstrated to regulations for othertransmitter components within the host product; torequirements for unintentional radiators (Part 15 Sub-part B “Un intentional Radiators”), such as digitaldevices, computer pe ripherals, radio receivers, etc.;and to additional authorization requirements for thenon-transmitter functions on the transmitter modul e(i.e., Verification, or D eclaration of Co nformity) (e.g.,transmitter modules may also contain digital logic func-tions) as appropriate.8.1.1 LABELING AND USER INFORMATION REQUIREMENTSThe RN4020 module has bee n labeled with its ownFCC ID number, and if the FCC ID is not visible whenthe module is installed inside another device, then theoutside of the finished product into which the module isinstalled must al so display a label referring to theenclosed module. This exterior label can use wordingas follows:A user’s manual for the product should include the fol-lowing statement:Additional information on labeling and user informationrequirements for Part 15 devices can be found in KDBPublication 784748 available at the FCC Office of Engi-neering and T echnology (OET) Laboratory DivisionKnowledge Database (KDB) http://apps.fcc.gov/oetcf/kdb/index.cfm.

These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equip-ment generates, uses and can radiate radio fre-quency energy, and if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the follow-ing measures:• Reorient or relocate the receiving antenna.• Increase the separation between the equipment and receiver.• Connect the equipment into an outlet on a circuit different from that to which the receiver is con-nected.• Consult the dealer or an experienced radio/TV technician for help.DRAFT
