Hi,

I recommend that you take a look at the UART example in the SDK. You can find the source code and the project file of the example in the following folder: <SDK_InstallFolder>\examples\peripheral\uart.

You can download the SDK 12.3 here.

hi, thank for your help but you did not understood my point maybe. I did not send anything on uart i just connected the TX and RX pin of ec25 to nrf51 board and flashed my program(i had set the baudrate to 115200 as per ec25 requirement) after successfully programming my nrf51 board i opened my termite as soon as i opened it was continuously sending "start[00]". And when i removed the TX and RX pin and changed the baudrate to 38400 and restarted the termit then my ble to uart communication was working fine. I want to know how can i make it to communicate with ec25 on baudate 115200.
