Great hardware deserves great software
Great hardware deserves great software. For the nRF53 and nRF52 Series we offer the nRF Connect SDK, a complete software development kit for developing Bluetooth Low Energy applications. It integrates the scalable Zephyr RTOS, a feature-rich Bluetooth LE protocols stack, a variety of samples, hardware drivers and much more.
We have ported the lower layers of our SoftDevices to the nRF Connect SDK, bringing with us the best-in-class interoperability our SoftDevices are known for. The result is the SoftDevice Controller. The SoftDevice Controller is combined with the Zephyr Bluetooth Host to form a feature-rich Bluetooth LE protocol stack. The stack is compatible with all nRF52 and nRF53 Series SoCs and supports Broadcaster, Peripheral, Observer and Central roles. It is a Bluetooth 5.2 qualified stack supporting 2 Mbps, Advertising Extensions, channel selection algorithm #2 and Long Range. It also supports Privacy 1.2, LE Data Packet Length Extension, configurable ATT MTU, L2CAP connection-oriented channels and LE Secure Connections.
The nRF5 SDK can be still used with the nRF52 Series, but it is in maintenance mode. For all new projects, we recommend the nRF Connect SDK.
