Hi,

All versions of S130 have been Bluetooth 4.2.

The first version of S110 was Bluetooth 4.0, the first version of S120 was Bluetooth 4.1, and the first version of S130 was Bluetooth 4.2.

The latest version of S110 is Bluetooth 4.1, the latest version of S120 is 4.1, and the latest version of S130 is Bluetooth 4.2.

Hi,

For new development on nRF51 series devices we recommend to use nRF5 SDK v12.3.0, which is the newest nRF5 SDK that supports the nRF51 series. The BLE SoftDevices provided with that SDK release are Bluetooth 4.2.

For further questions regarding Bluetooth specification version numbers, I refer to our online documentation.

My product used to use S110 in sdk8.0 of nrf51802 chip. Now it needs Bluetooth 4.2 version if it is certified, and the S130 under sdk8.0 will change into Bluetooth 4.2 with less changes
