Step by Step quide to STM32F4 NRF51dk

[nrfnovice]

Hi Everone/Nodiac

I had tried so many threads and previous questions but not bale to get my answer so asking after two weeks.

I am willing to send a string from stm32f4 uart to my mobile via nrf51dk

1. I am confused in step by step process to communication the nrf51dk with stm32F4

Do I need to just put s130 soft device in the nrf51, or I have to put ser_130_uart or both

I am trying to modify the STM32Lx nucleo example to use for STM32f4 with Nrf51dk

where they mention put soft device, serialization hex file and than application its very confusing for me

2. could you tell me approach to send first byte our via nrf

3. Any code example anyone have for nrf51 wth stm32f4

Thanks

Easiest approach would be to download sdk 12 zip file and find Nordic UART service client demo. Inside the zip is precompiled hex file that contains everything you need to make it run. The app listens to UART on one end and can be connected by Nordic UART demo for Android over BLE. Just look for nus in examples/ble_peripheral directory
