Uart interface in sample project ble_app_uart_c does not work on nRF51822

[Louis_263]

Hello,
when I try to send data via the UART interface using a printf statement, unfortunately this does not really work. Only one byte is sent and after that the application hangs. I have attached a photo with a code snippet of where the program hangs (in the write function at the position app_uart_put).

I hope that someone can help me.

Hi,

using a printf statement, unfortunately this does not really work.

1) Could you post the the code you used? where did you call printf? in main() ?

2) Do you see "Uart_c Scan started" being printed when you run the ble_app_uart_c example?

3) What SDK version are you using?

4) What serial terminal are you using?

5) Custom board or nRF51-DK?

6) Are you using UART with or without flow-control? Is the terminal configured with the correct flow-control settings?

Hi Sigurd,

i just recreated the project and now it works. I must have chosen the wrong settings before.

Thanks for your help
