3 low power Bluetooth modules WF121, BLE113 and SLSTK3301A comparison, which excellent?

Mandarin, simple, safe independent WF121 Wi-Fi module reference design for fast-landed Internet of Things applications Introduction: WF121 is a separate Wi-Fi module that provides complete integrated 2.4 GHz 802.11 B / g / N radio, TCP / IP protocol stack, and 32-bit microcontrollers for simple, low-cost and low-power embedded applications. MCU) platform. Power Wireless IP connection. It also provides a flexible peripheral interface, such as SPI, I2C, ADC, GPIO, and Timers, can connect various peripheral interfaces directly to the WF121 Wi-Fi module. The WF121 Wi-Fi module also allows you to use a simple BGScriptTM scripting language and free development tools to embed the end user application into the 32-bit MCU. This eliminates the need for additional MCUs and enables end users to develop smaller and lower Wi-Fi devices. In applications where external MCUs are needed, WF121 can also be used to similar modem modems. Also included with 802.11 access points and HTTP server functions, it is easy to configure and direct access to mobile phones, tablets, and PCs. With integrated 802.11 radio, antenna, single power and CE, FCC and IC regulatory certification, WF121 can provide low risk and rapid marketing time for applications that require Wi-Fi connection. Be High integration of wearable device solution - small, low-power intelligent Bluetooth module BLE113 reference design Introduction: BLE113 is an intelligent Bluetooth module for small and low power sensors and accessories. It integrates all the features required for Bluetooth Smart applications, including Bluetooth radio, software stacks, and GATT-based profiles. The BLE113 smart Bluetooth module can also host the end user application, which means that there is no need for an external microcontroller in a size or price-limited device. In addition, BLE113 has a flexible hardware interface that can be connected to different peripherals and sensors, which can be powered directly with a standard 3 V button battery or a pair of AAA batteries. In the lowest power sleep mode, it consumes only 500 NA and will wake up internally.
