![]() Silicon Labs Bluetooth provides two non-volatile memory options: NVM3 and Persistent Storage (PS) are supported with B/MG1, B/MG12, B/MG13, while NVM3 is supported with B/MG21 and B/MG22. You can adjust the memory block size for your data and settings. Host Network Co-processor (NCP) interfaces include 4-wire UART with RTS/CTS control or 2-wire UART without RTS/CTS GPIOs for sleep and wakeup management. Higher link layer packet size of up to 251 bytes and ATT protocol packet size of up to 250 bytes allow you to increase data throughput and reduce power consumption (larger packets reduce overhead). Silicon Labs Bluetooth provides you with all the specified pairing processes, including Just Works and Man-in-the-Middle with numeric comparison and Out-of-Band passkey. ![]() It avoids energy-intensive GATT database discovery of a remote device during each connection setup by storing a local copy for future use. GATT Caching enables your Bluetooth applications a faster client reconnection time and lowers power consumption. Silicon Labs supports all GATT-based Bluetooth profiles and services, including the GATT caching. The extended advertisement packet size of up to 1650 bytes is supported, allowing you to fit in more payload. The three advertisement channels now only carry pointers to the advertisements, which are transmitted on the 37 data channels. The Bluetooth Advertisement Extensions offload the three advertisement channels to allow more capacity for beacons, way-finding, indoor navigation, and asset tracking. Series 1 hardware supports up to 13 simultaneous connections. Silicon Labs Bluetooth and Series 2 hardware support 32 simultaneous connections – the high number of connections allows you to connect more nodes per device or base station and reduce the costs of large IoT solutions. (SoCs and modules for 2M PHY: B/MG12, B/MG13, B/MG21, and B/MG22) The 1M PHY delivers a throughput of 700 kbps. Our Bluetooth provides the 2M PHY modulation for your high-data throughput IoT applications to unleash a throughput of 1300 kbps on selected SoCs and modules. (SoCs and modules for Long Range: B/MG13, B/MG21, and B/MG22) LE Coded PHY improves sensitivity by 4-6 dB, which reduces retransmissions, and increases battery life and connectivity reliability. LE Coded PHY (500kbps and 125kbps) enables your Bluetooth devices with up to two times (2X) longer range compared to the 1M PHY modulation – which can correspond to several hundreds of meters. It enables high-accuracy positioning of below one meter (<1 m) for your asset tracking and indoor positioning applications – 3-5 times higher accuracy than RSSI.ĭevelop accessories for the Apple HomeKit ecosystem faster and with lower interoperability risks by building upon the full Apple HomeKit support on our BLE stack – it is available via the Apple MFI license on a wide range of SoCs and modules.Īre you developing IoT devices with multiple 2.4 GHz protocols such as Wi-Fi and Bluetooth? With Silicon Labs’ Wi-Fi Coexistence, you can reduce interference and increase reliability! It is based on packet traffic arbitration (PTA) and allows the Bluetooth device to coordinate transmitting and receiving with the collocated Wi-Fi device. Silicon Labs Bluetooth Direction Finding is based on the angle of arrival (AoA) and angle of departure (AoD) techniques. ![]() Here’s a rundown of all the crucial features on the Silicon Labs stack.ĭynamic multiprotocol allows you to run Bluetooth, Thread, Zigbee, and Proprietary protocols reliably on one radio, by time-slicing radio operations seamlessly between multiple stacks. ![]() Keep your products ahead of the competition! Silicon Labs Bluetooth Low Energy stack is in the frontline to support the latest specifications and it delivers all the essential features among the first in the world.īluetooth Low Energy Software Features and BenefitsĪdd the most valuable Bluetooth Low Energy features to your IoT applications. The single-stack approach speeds up development and radically minimizes Bluetooth SW and HW migration efforts to your new products – it results in a more consistent code and reduces software development and maintenance costs. With Silicon Labs, you have just one proven, hardware-agnostic software stack and API for Bluetooth Low Energy. It consists of an extensive library of example projects, peripheral drivers, the Bluetooth Low Energy protocol stack, and the API. The Bluetooth Low Energy Software Development Kit is part of the Silicon Labs GSDK. ![]()
