Use UART in Characteristic Tutorial

[Sascha]

Hello again,

i wanna use the UART communication for transfering data from my µc to the nrf51 and vice versa.

For a test i used the ble_app_uart example and it works fine. I got my data in the uart_event_handler from app_uart_fifo.c. Now i want to use UART inside the characteristic-master example, which i use as my ground project-> if there is a better way to built up a project like this, pls tell me :)

What i have to do to include the UART part, to get the data as i did it in the app_uart example? if i try to get it in the uart_event_handler from app_uart.c i dont get any data.

Thank you

*additional data: i user nRF51DK with SDK11

Hi

As I understand you , you want to use UART together with BLE, am I correct? I anyway don't realize what example is "characteristic-master example" that you refer to.

Have you looked at the ble_app_uart example in the nRF5 SDK 11.0.0? It implements communication with the hardware UART and also transfers data over BLE via the NUS (Nordic UART service) service. In that example, when you send data from your microcontroller to the nRF51 via the UART, it should appear on a connected BLE peer device.

Ok i try to explain. I want a simple hardware UART communication between the nRF51 and our microcontroller. In a simple test i only want to transfer one byte: 0x01 over UART (P0.09) from our µc to nRF51 and when received i send 0x02 back over UART(P0.11) to our µc. 0x01 will correct received by nRF51 in uart_event_handler from app_uart.c, but when i want to send 0x02 back from nRF51 to our µc, there is no data send over the uart tx pin.
