INTERFACE DESCRIPTION
AF
FIGURE 3-1:
Figure 3-1 illustrates the interface between PIC microcontroller and RN4020 module. The minimum interface
consists of UART and WAKE HW line. This enables the
microcontroller to communi cate with RN 4020 module
using ASCII comman d API. T he command API is
described in Sec XX.
CTS/RTS Hardware Flow Control
3.1
For customer applications using the Microch ip Low
Energy Data Protocol (MLEDP), Pin 8 (CMD/DATA) is
required. CTS/RTS hardware control is also highly recommended for this service to avoid buffer overruns.
DSXXXXXXXXA-page 6
3.2
Microchip Low Energy Data
Protocol (MLDP)
The Microchip Low En ergy Data Protocol i s a private
BTLE service that provides a 20kbps serial data transport over Bluetooth Low Energy on the RN4020. Pin 8
(CMD/DATA) is required. CTS/RTS hardware control is
also highly recommended for this service to avoid data
loss.

SUPPORTED SERVICES
The RN4020 firmware support the following built-in profiles listed in Table 7-1 below. The services are enabled
via Command API and serviced in the same manner.
Each service manages “Characteristics” which as data
values are declared and defined by Bluetooth. The values for ea ch characteristic are ca ched in modules
memory and can be read by another Bluetooth device,
such Smartphone acting in Central role. The values of
every Characteristic are updated via Command API
over UART.

PCB Antenna
The PCB antenna is fabricated on the top copper layer
and covered in solder mask. T he layers below the
antenna do not have copper trace. It is recommended
that the module is mounted on the edge of the host
PCB. It is permitted for PCB material to be below the

Public and Private Services
The RN4020 provided the ability to cre ate customer
services. If the services a re supported on both end
points of a Bluetooth Low Energy connection, such as
Central and Peripheral devices, data can be
exchanged. For example, two RN4020 modules can
define a custom (private) service with its own u nique
characteristics. Data can be exchanged easily via
Command API.
Private services are not registered with the Bluetooth
SIG, and therefore not in teroperable with other Blu etooth Low Energy device s, unless the device implements the private service. An example of a bui lt-in
private service is Microchip Streaming Data service.
Refer to “ RN4020 Command Reference”, docxxxxxxxxx, and Application Note AN-xxxxxx for an example on h ow to crea te a custom service using the
RN4020.

LABELING AND USER
INFORMATION REQUIREMENTS
The RN4020 module has bee n labeled with its own
FCC ID number, and if the FCC ID is not visible when
the module is installed inside another device, then the
outside of the finished product into which the module is
installed must al so display a label referring to the
enclosed module. This exterior label can use wording
as follows:
RN4020:
Contains Transmitter Module FCC ID: T9JRN4020
or
Contains FCC ID: T9JRN4020
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference,
and (2) this device must accept any interference
received, including interference that may cause
undesired operation
AF
The RN4020 module has received Federal Communications Commission (FCC) CFR47 Telecommunications, Part 15 Sub part C “Inte ntional Radiators”
modular approval in accordance with Part 15.212 Modular Transmitter approval. Modular approval allows the
end user to integrate the R N4020 module into a finished product without obtaining subsequent and separate FCC approvals for i ntentional radiation, provided
no changes or mo difications are made to the modul e
circuitry. Changes or modi fications could void the
user’s authority to op erate the equipment. The end
user must comply with all of the instructions provided
by the Grantee, which indicate installation and/or operating conditions necessary for compliance.
8.1.1
8.0
The finished product is required to comply with all applicable FCC equipment authorizations regulations,
requirements and equipment functions not associated
with the transmitter module portion. For example, compliance must be demonstrated to regulations for other
transmitter components within the host product; to
requirements for unintentional radiators (Part 15 Subpart B “Un intentional Radiators”), such as digital
devices, computer pe ripherals, radio receivers, etc.;
and to additional authorization requirements for the
non-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 functions) as appropriate.
 2014 Microchip Technology Inc.
A user’s manual for the product should include the following statement:
This equipment has been tested and found to comply
with the limits for a Class B digital device, pursuant to
part 15 of the FCC Rules. These limits are designed
to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses and can radiate radio frequency 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 following 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 connected.
• Consult the dealer or an experienced radio/TV
technician for help.

RF EXPOSURE
8.2
Canada
The RN4020 module has been approved for mixed

with other transmitters may need additional evaluation in accordance with FCC multi-transmitter
guidelines.
The RN4020 module has been certified for use in Canada under Industry Canada (IC) Ra dio Standards
Specification (RSS) RSS-210 and RSSGen. Modular
approval permits the installation of a modu le in a host
device without the need to recertify the device.
All transmitters regulated by FCC must comply with RF
exposure requirements. KDB 447498 General RF

The New Z ealand radio regulations do not provid e a
modular approval policy similar to the United States
(FCC) and Canada (IC). However, RN4020 module RF
transmitter test reports can be used in part to demonstrate compliance against the New Z ealand “General
User Radio License for Short Ra nge Devices”. New
Zealand Radio communications (Radio Standards)
Notice 2010 calls up the AS / NZS 4268:2008 industry
standard. The RN4020 module test reports can be
used as part of the product certification and compliance

The Australia radio regulations do not provide a modular approval policy similar to the United States (FCC)
and Canada (IC). However, RN4020 module RF transmitter test reports can be used in part to demonstrate
compliance in accordance with ACMA Radio communications “Short Rang e Devices” S tandard 2004 (The
Short Range Devices standard calls up the AS/NZS

test reports can be used as part of the product certification and compliance folder. For more information on the
RF transmitter test reports, contact Microchip Technology Australia sales office.

To meet overall Australian final product compliance, the
developer must construct a compliance folder containing all relevant compliance test reports e.g. RF, EMC,
electrical safety a nd DoC (Declaration of Con formity)
etc. It is the responsibility of the integrator to know what
is required in the compliance folder for ACMA compliance. All test reports are available on the RN4020
product web page at http://www.microchip.com. For

Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
