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

Thanks for your clarification.

Do you use UART hardware flow control? If so, then having the CTS line high prevents the UART from sending bytes.

Thank you!! This was the solution. I changed

APP_UART_FLOW_CONTROL_ENABLED

to

APP_UART_FLOW_CONTROL_DISABLED

Now it is running. I dont need the flow control. To your question for the characteristic-master example, i used this one Characteristic Example when i download the zipped file, the folder is named "nrf5-ble-tutorial-characteristic-master" so my description. Thank you Stefan!
