Hi.

I am using the  X-NUCLEO-IDB04A1 with Nucleo STM32F103 and the available demos are only for F4, L0 and L4. This is fine as I want to learn about programming bluetooth anyway. The BLUENRG chip on the expansion board is also a MCU and can be programmed. 

My question is: Do I need to program both devices and if so how, or can I treat the BLUENRG as a simple peripheral and control with standard SPI? Does the BLUENRG need to be programmed or is that only when using it as an MCU?

Thanks.

M.

    Quick guide - it's SPI device:

    I know that its SPI but looking at the datasheet it actually is more of a complete MCU. As I will already be using an MCU, I dont need two. So I suppose my question is: Can the BLUENRG behave like a simple SPI device, does it need to be flashed seperately, is there default code in it/bootloader, can I read data from SPI straight away. Just looking to know this before I get stuck in.

    Thanks.
