Bespoke 2.4 GHz wireless development

There are occasions when complete control of the wireless link is required for reasons such as low latency, reduced packet size or particular unique protocol behavior.

The nRF52 and nRF51 Series wireless SoCs all support 2.4 GHz proprietary development. As multiprotocol wireless SoCs they offer simultaneous Bluetooth Low Energy operation, or another supported protocol, if the application demands it. Whilst 2.4 GHz proprietary development does not offer the interoperability that comes with standards like Bluetooth, it can offer special abilities to tailor both ends of a communication link for maximum efficiencies.

The nRF5 SDK has a range of resources for proprietary 2.4 GHz development and includes Nordic's own 'Gazell' proprietary 2.4 GHz protocol.
