Development board nRF52832 with multilink + UART

[Yoann_F]

Hello everybody !

Here I am designing a system with 3 development boards nrf52832, where a card called "central" is connected to the computer by USB and this board will then communicate with the other 2 boards "device" with the code from this this tutorial: github.com/.../custom_ble_service_example.

So, my current problem is that I would like to have my computer communicate with the "central" development board. I then used the code example of the sdk "ble_app_multilink_central" and I added to it the parts of the code "ble_app_uart_c" to initialize the UART. During initialization, I get error 8 with APP_ERROR_CHECK (err_code). As I use the traces NFR_LOG I think that the problem thus comes from that. I would like to know if there is a way to debug (by seeing traces on the COM port). And for example what does it take to use printf? (I use Segger with the Nordic SDK 14.2).

Thank you in advance for your assistance !

Hi Yoann_F, 

do you added the Uart part to the Multilink or some parts of the Multilink to the Uart example?

Hi !
I added some of the UART to the multilink.

If you send your Data with the gattc_write function, how you recived? 

Do you have something like a example code which would help? 

[Yoann_F]

At the moment my shipping code is not ready yet.

For the Peripherals, have you used the blink example? 

If I use the Code above I will get the error:  #5: cannot open source input file "nrf_sdh.h": No such file or directory

Do you know why it can't find this file ? I copied your code in the Multilink example.

[Yoann_F]

no I use another example to establish a connection, you just need to change the "static char const m_target_periph_name [] =" what you want ";"

Have you added the "nrf_sdh.h" to your project?

[MootSeeker]

Which example you have used?
