In addition to the 31 bytes of advertising data, the device doing the scanning can request the scan response data. For example, the heart rate central example finds the first heart rate sensor in range and connects to it automatically. While central devices do not advertise, they may scan for devices in range and use their advertising data to determine what to connect to.

Custom data: beacon data for iBeacon, for example.

Service UUID: UUIDs supported by your peripheral device.

Local Name: a descriptive name for your peripheral device.

Type: Basic features supported by the peripheral device.

Standard advertising payload data options include: There are some standard types, or you can use a vendor defined type (0xff) to send any arbitrary data in your advertising payload. The advertising data is small (31 bytes, BLE_MAX_ADV_DATA_LEN). Because of radio congestion and random packet loss, it might take more than one advertising broadcast before the message is received. For devices where latency is not important and want to reduce power consumption, it could be 1 to 2 seconds. The normal fast advertising interval is 100 to 500 milliseconds. This prevents two devices with the same advertising interval from being stuck transmitting at exactly the same time forever and possibly interfering with each other. The interval for advertising ranges from 20 milliseconds to 10.24 seconds, though there is a random 0 to 10 millisecond additional delay added. A mobile app can look for this data and respond to it.įor example, a beacon embedded in a store display might allow a store app to provide additional information about the item, provide a coupon, or customize a store map.

A peripheral device can broadcast continuously as a beacon.Ī BLE advertiser doesn't require any authentication between the peripheral device and the mobile app - the advertiser just continuously outputs data over a short range, typically around 10 meters.

It allows a BLE central device (like a mobile app) to be able to discover the peripheral device.

Enter authentication manually Major concepts AdvertisingĪdvertising is the process by which a BLE peripheral device broadcasts periodically. Workbench or the Web IDE and other techniques directly, if you prefer.Ĭannot use Particle Single Sign-On from outside the Particle domain. This is optional, as you can use Particle You can interact directly with your device from this tutorial page by logging into your

Additional features were added in Device OS 3.0 and 3.1. It is not available in earlier Device OS versions. BLE support was in beta test in Device OS 1.3.0. The SoMs do not have built-in antennas.Ī good introduction to BLE can be found in the Adafruit tutorial.īLE is supported in Device OS 1.3.1 and later.

The B Series SoM (system-on-a-module) requires the external BLE/Mesh antenna connected to the BT connector. The BLE protocol can use the built-in chip or trace antenna, or an external antenna if you have installed and configured one.

Particle devices do not support Bluetooth 5 mesh. Particle devices do not support Bluetooth A2DP and can't be used with Bluetooth headsets, speakers, and other audio devices. When your Particle device is configured as a central device, it might gather data from a sensor like a heart rate sensor and upload it to the cloud over Wi-Fi or cellular, taking the place of a mobile phone app.īLE is intended for low data rate sensor applications. Computers with BLE support can also be central devices. Central devices are things like mobile phones and tablets that communicate with peripheral devices.It can also be programmed to be an iBeacon, to allow iOS apps know they are near a specific beacon. When your Particle device is configured as a peripheral, it might be attached to a sensor and provide that information to a mobile app. Peripheral devices are typically low-power devices like heart rate sensors, body weight scales, thermometers, proximity tags, etc.Particle devices support both the peripheral and central roles: Bluetooth is used to configure your device from the Particle mobile apps for iOS and Android, and Bluetooth LE (BLE) can be used in your firmware to communicate with other devices that support BLE. Gen 3 devices (Argon, Boron, Xenon) support Bluetooth.
