nrf51822 uart question

[DragonAnger]

First of all, Because of my poor English, and I'm newbie this kind of work.

I'm not sure you can understand my question. But I'll try

Currently, To see my borad's log datas, I use debug serial(uart) and connect to PC.

And my purpose is to see the log datas using my Smartphone using BLE.

So I bought nrf51822+ble400 and I tried sample code in SDK12(ble_app_uart) and

NRF Toolbox with my android phone. And It works.

So I tried to connect nrf51822 to my company's borad using uart.

I expected to the board's log datas on my phone, but it didn't work.

What I want to do is this:

My Board ->(uart) nrf51822(+ble400) -> (BLE) my smartphone(NRF Toolbox)

As I said, I'm newbie. so I don't know how make this work, how I search.

So some guidance or links will be very very helpful to me.

If you can't understand my question, please ask me. I'll try to make you understand.

Thanks.

It looks like you need to customize .\examples\ble_peripheral\ble_app_uart\ example project from Nordic nRF5 SDK in order to receive data over physical (wired) UART and push them over BLE link running Nordic BLE UART Service (NUS).

Thank you for your answer!! Can you give me some information about customizing ble_app_uart? I'm not sure but I think Data receiving is a problem. Is there any difference between UART comunication using usb and UART pin on mother board(BLE400)?

[DragonAnger]

In addition, I tested hardware, and data comes perfectly. I think it's software problem as you said.

Which pins are you using for the UART interface? Do I understand you correctly that you are able to send UART messages to/from the nRF51822 device using the USB to UART interface on the BLE400 board?

I solve this problem!

I changed pin number in "pca10028.h" in "ble_app_uart"

#define RX_PIN_NUMBER 11 #define TX_PIN_NUMBER 9

to

#define RX_PIN_NUMBER 5 #define TX_PIN_NUMBER 6

nrf51822 uses different pin USB to UART and wired UART.

Thanks for the comments all of you!
