3.0 MICROCONTROLLER TO RN4020 INTERFACE

FIGURE 3-1: INTERFACE DESCRIPTION

Figure 3-1 illustrates the interface between PIC micro-

controller 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.

3.1 CTS/RTS Hardware Flow Control

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.

3.2 Microchip Low Energy Data Protocol (MLDP)

The Microchip Low En ergy Data Protocol is 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.

Refer to “ RN4020 Command Reference”, for more

information on how to configure the MLDP service
mandatory for DFU over UART.

7.1 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 it s 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”, docxxx-

xxxxxx, and Application Note AN-xxxxxx for an exam­ple on h ow to crea te a custom service using the

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 us ed 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
4268:2008 industry standard). The RN4020 module
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 Conformity)
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
more information on Australia compliance, refer to the
Australian Communications and Media Authority web
site http://www.acma.gov.au/.

DRAFT

• 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.”
