What is the difference between "uart_example" and "ble_app_uart"(under path S110/experimental) for PCA10001?

Hello all,

I little confused with these two examples as mentioned in my question. Both examples are different and their use case is also different. Can somebody please suggest which one to use when?

Hi, Simple uart app is just for uart communication (in ARM core) You can send/receive data through UART line. (9, 11 pin for EV board) The example is not using bluetooth at all, only ARM core.

ble_app_uart is somthing like SPP (Serial Port Profile). it sends data through ble when it recevie data from UART. And also, it sends data to UART when data comes into ble. For that fucntion, it configures BLE stack, SoftDevice, etc.

Thanks a lot LKH! As you mentioned in [[https://devzone.nordicsemi.com/question/12238/how-to-send-data-from-pic-controller-to-nrf51822-using-uart/?answer=12246#post-id-12246]] that I should use experimental/ble_app_uart. OK! So do i need to have any physical pin connection between Pic and nrf-ble chip? Can I use nus custom service for both the communication between Pic & nrf and between nrf & phone app? Looking forward to your reply.
