Any suggestion Bluetooth Low Power Modules for STM32F429 Discovery

I'll offer something a little more useful;

Nordic Semi has the nRF8001 chip, SPI + interrupt interface, but their example code sucks really badly. It would take significant effort to figure out what their code is doing and adapt it to your project.

ST has the BlueNRG chip, SPI + interrupt interface, nice looking example code but has a bunch of the Bluetooth stack in a precompiled library. If you aren't using the same compiler as them, and possibly the same target processor family, you may be hooped. (edit: It looks like the stack is built into the BlueNRG chips, so the target system shouldn't be an issue).

Try Roving Network RN41 or RN42 . Operates using AT Command via USART.

Pretty good i will say .

I found that nRF51822 is a good BLE 4 chipset. It has a 32-bit Cortex-M0 SoC. I am not sure how difficult to make it work along with STM32F4.

It is better to have all programming just in STM32F4 while a BLE chip is a Bluetooth 4.0 hardware component.

Unfortunately this is Bluetooth 2.x chip.
