Which SDK nrf51802 runs supports Bluetooth 4.2?

[Nguyen Hoan Hoang]

The last SDK for nRF51x series is version 12.3 it only supports BLE 4.x.

Hi,

The latest version of our SDK supporting the nRF51 series is nRF5 SDK v12.3.0. This is the recommended release to use with all nRF51 series devices. nRF51802 is compatible with nRF51822, although you may have to take into consideration the anomalies listed in the Product Anomaly Notification.

Hi,

Yes, it supports Bluetooth 4.2. The S130 SoftDevice is a precompiled and linked binary image implementing a Bluetooth 4.2 low energy protocol stack for the nRF51 Series of SoCs.
