Hi Aryan,

    advertising_init();
    conn_params_init();
    for(int i=0;i <100000;i++);
for(int i=0;i <100000;i++);
    printf("%s",start_string);

you c# software should always in scanning to get the port number. Once you get the port number immediately connect it.

make sure RtsEnable = True & DtrEnable = True my SDk version is 9.0.0 my hardware is latest development kit v1.1.0 The program didn't work, when I try to use uvision 5.16a pack installer to download and run the code. I downloaded sdk9.0.0 in Device folder and extract then I went to Load "C:\Keil_v5\ARM\Device\SDK9.0.0\examples\ble_peripheral\ble_app_uart\pca10028\s110\arm5_no_packs\_build\nrf51422_xxac_s110.axf" and open the project using uvision 5.16a

do let me know if you need more info.

Note: Even if you wont be able to see Start... in c# program. Go head and connect it with Master control panel then do the send & receive. it will work. Thanks and Regards Lakshman,PMP,PMI-RMP

Where did you add delay? can you please post the code snippet of this change. Also please mention which SDK version and hardware version you are using.

Hi Aryan, Thank you very much for your reply. Yes initially I did RtsEnable = True & DtrEnable = True. But I didn't get the Start... from BLE UART.. After giving some delay in BLE UART I am able to see the Start....

As i am new to this forum.Kindly help me to close this issue & mark as right answer.

RtsEnable = True & DtrEnable = True and give some delay in BLE UART before printing "Start..."

Thanks Lakshman,PMP,PMI-RMP

I am not an expert in microsoft API but I had a quick look into its documentation. Shouldn't be RtsEnable be set to true for handshake to work?

Hi Arayan, Thanks for your reply. I don't need driver for windows since I am planning to use UART application to send and receive data.

Used ble_app_uart_s110_pca10028 example UART porgram as nRF51 UART slave.

I am facing issue when I use visual studio 2010 C# for programming. I am unable to get "START..." from nRF51 UART slave. My serial Port Configuration in C# program is

BaudRate  = 38400
DataBits   = 8
DiscardNull = False
DtrEnable = False
GenerateMember = True
Handshake = RequestToSend
Modifiers = Private
Parity = None
ParityReplace =63
Portname = COM89
ReadBufferSize = 4096
ReadTimeout = -1
ReceievedBytesThreshold = 1
RtsEnable = False
StopBits = One
WriteBufferSize = 2048
WriteTimeout = -1

But if i use Hypererminal with the same configuration below. I am able to get "Start..." from nRF51 UART slave.

Bits per Second = 38400
Data bits = 8
Parity = None
Stop bits = 1
FlowControl = Hardware

Kindly advise Thanks and Regards Lakshman,PMP,PMI-RMP

There is a BLE driver for windows that can be used to interact with nRF chips. You can find it here. I never used C# before, but i think it is safe to assume that it gives you a way to interact with the drivers and libraries.
