Soft device specification details

Hello All

Could you please tell me what is the main difference between following S130,S120,S110, Please help me

(What about to read it in the Infocenter?) If you are going to develop anything on nRF51 it's highly recommended to go with S130 V2 because that's the one with latest fixes and potentially the only one maintained (if there will be any SW maintenance on nRF51 at all, Nordic is pushing all new developments on nRF52).

The S110 SoftDevice Specification can be found here.

The S110 SoftDevice is a Bluetooth low energy (BLE) Peripheral protocol stack solution. It integrates a low energy controller and host, and provides a full and flexible Application Programming Interface (API) for building Bluetooth low energy System on Chip (SoC) solutions.

The S120 SoftDevice Specification can be found here.

The S120 SoftDevice is a Bluetooth low energy (BLE) combined Central and Peripheral protocol stack solution, which means that the SoftDevice can be initialized to run either as a Central protocol stack or as a Peripheral protocol stack. When initialized as a Central, it supports up to eight simultaneous Central role connections and an Observer. When initialized as a Peripheral, is supports a Peripheral connection and a concurrent Broadcaster. The SoftDevice integrates a low energy controller and host, and provides a full and flexible Application Programming Interface (API) for building Bluetooth low energy System on Chip (SoC) solutions.

The S130 SoftDevice Specification can be found here.

The S130 SoftDevice is a Bluetooth low energy (BLE) Central and Peripheral protocol stack solution. It supports up to eight connections with an additional Observer and a Broadcaster role all running concurrently. The S130 SoftDevice integrates a BLE Controller and Host, and provides a full and flexible API for building Bluetooth Smart nRF51 System on Chip (SoC) solutions.
