UART Communication STM32

[mweaver]

I am trying to program the Nordic nRF51822 MDBT40 Series module to communicate to an STM32 processor chip. The way I understand the procedure is as follows:

First, I must flash the soft device to the module. I am not sure whether the correct version for this module is the s110 or the s130 and I'm not sure how to find out. Here is more info on the module I am using: https://www.raytac.com/upload/download_files/67c126f04087aeb26db74ad04625782e.pdf

Once this is completed, I can connect to the module via the nRF Connect app. 

Is the soft device the only thing I need to flash to the bluetooth module to enable it to transmit to and receive data from the stm32 chip via a UART connection?

Are there any C code examples you're aware of that I could learn from to program the STM32 chip?

Thanks

Hi,

Please take a look at the "Compatibility matrix" to see what combinations of SDK and Softdevices you can use with your nRF51 chip. 

Is the soft device the only thing I need to flash to the bluetooth module to enable it to transmit to and receive data from the stm32 chip via a UART connection?

 You need to program an application to run on top of the softdevice. I think you may find the following links useful:

-  UART/Serial Port Emulation over BLE (example application available in nRF5 SDK) 

-  Running examples that use a SoftDevice
