BlueNRG app for smartphones

An application is available for iOS™ and Android™ smartphones or tablets that also works

with the BlueNRG-1 BLE sensor profile demo. This app enables notification of the

acceleration characteristic and displays the value on screen. Data from environmental

sensors are also periodically read and displayed.

BlueNRG-1 sensor profile demo: connection with a central

device

This section describes how to interact with a central device, while the BlueNRG-1 BLE

stack is acting as a peripheral. The central device may be another BlueNRG-1 device

acting as a BLE master, or any other Bluetooth smart or Bluetooth smart ready device.

The BlueNRG-1 BLE stack must first be set up by sending a series of BLE API commands

to the processor.

10.2.1

Initialization

The BlueNRG-1 BLE stack must be correctly initialized before establishing a connection

with another Bluetooth LE device. This is done via:

aci_gatt_init();

aci_gap_init(GAP_PERIPHERAL_ROLE, 0, 0x07, &service_handle, &dev_name_char_handle,

&appearance_char_handle);

See BlueNRG-1 BLE stack API documentation for more information on these and following

commands.
