Bluetooth® Low Energy Protocol Stack Fast Prototyping Board Host Sample

1. Overview

This application note describes how to transmit sensor information via Bluetooth using the RL78/G14 Fast Prototyping Board and the RL78/G1D BLE Module Expansion Board. The sensor uses the Renesas HS3001 Humidity and Temperature Sensor Module (humidity, temperature).

The Host Sample is a Host MCU program that runs on the RL78/G14 Fast Prototyping Board using the Bluetooth Low Energy Protocol Stack (BLE Protocol Stack) Modem configuration. Controls the RL78/G1D module (RY7011) that configures the RL78/G1D BLE Module Expansion Board of the BLE MCU connected by UART 2-wire branch connection and pairing information can be saved in the RL78/G14 Fast Prototyping Board.

）

(Note1

. In addition, by using the Security Library

(Note2)

, pairing execution

The module firmware for operation check is written in RY7011 at the factory, and can be controlled from the

(Note3)

Host MCU program using the rBLE API

of the BLE protocol stack.

Notes: 1. In addition to TxD and RxD, which are UART data signal lines, the Host MCU has a WAKEUP

signal line for waking up the BLE MCU at the time of data transmission. The WAKEUP signal line branches TxD of Host MCU and connects with WAKEUP of BLE MCU. For connection between Host MCU and BLE MCU, refer to "6.4.3 Application Circuits".

2. For details on the Security Library, refer to the "Bluetooth

Low Energy Protocol Stack Security

Library" (R01AN3777).

Note: Connect to PMOD2 when using the I2C communication Pmod

module. Then change the pin that assigns the function of serial interface IICA with the peripheral I/O redirect function of RL78/G14. Refer to "Table 3-2 PMOD2 connector pin assignment" for pin assignment.

The overview of the host sample is shown below.

 It uses rBLE API and executes below operations.

• After power up, it starts broadcasting.

• Connection is established by the connection request from Remote Device.

• It executes pairing and starting encryption if Remote Device requires.

• Enable the General Purpose Communication Profile with Indication permission from Remote

Device.

• Erase the security information stored in the data flash with the USER SW.  It is implemented a simple scheduler for management processing sequence.  It changes the RL78/G14 state into the STOP mode if there is nothing to execute.  It supposes that peer device is a smart phone (Android device or iOS device).
