Stream data between two nRF51 devices over BLE to UART

Hello! I'm really interested in this example but when I try to compile this example, compiler returns me several erros - files cannot be found (error: #X: cannot open source input file "app_util.h": No such file or directory".

I'm using SDK V8.0 and the patched version code.

EDIT: OK, the patched code works fine. When adding the extracted example folder to SDK folder, you must edit/correct the files' paths.

@sele835: Please use SDK v8.0.0 , not v8.1.0

Hi Bui. I am trying to do the same thing but with two nRF51 DK boards (pca10028). When I import the main file from your code into an existing hrs project and try to build it, I get linker error: ._build\nrf51422_xxac_s120.axf: Error: L6200E: Symbol GPIOTE_IRQHandler multiply defined (by app_gpiote.o and nrf_drv_gpiote.o)

Hi kilianod: I found a bug in the code. You can try the fixed branch here.

What you need to do to test is to connect the DK boards to PC (s) and type something into one COM Port after they get connected. The DK will send what you type to the other DK, and will be forwarded to the other COM Port on every 20 byte entered.

So I got it to compile, but I'm not sure what to do with it next and how to connect the two devices. For my setup, I have two nRF51-DK boards. One with the linked example running on S120, while the second device has S110 and running the ble_app_uart_s110_pca10028 example code as suggested on the Github readme file. I have the first board connected to a Serial Terminal program and I get the message "Start.." and it does nothing else. Am I missing something here?

Thanks

Thanks for the link. However, I'm having trouble compiling the code, I get the following error, any idea what is causing it, looks like a missing library or something:

..\..\main.c(477): error:  #136: struct "<unnamed>" has no field "gap_enable_params"
  ble_enable_params.gap_enable_params.role              = BLE_GAP_ROLE_CENTRAL;

@Kilianod: We made an example for the nRF51 on client side (central role). You can have a look here.

What it does is to act as the phone in the example you pointed to in your question.
