10028board, not scannable.

Sounds really strange. Please try to do an Erase All, program SoftDevice and then application.

I don't believe it. I closed project and open again and change source code a little. It's same to only add '//' I rebuilt it. But I met the same error before I downloaded SDK11, 'hex has data in Softdevice region'.

What happen? So I fixed change to the original source code but same error occur.

I didn't change anything in the code. What should I do? Download SDK 11 again?

Perfect.

I just put simple nus-sending function 'ble_nus_string_send(&m_nus, p_data, length)' in 'nus_data_handler' then it works as a ble loop back test.

Thanks for Nordic's rapid customer support. Thank you!

Np, but please accept my answer ;) It is not a loopback example. You can send characters from the app to the nRF51 over BLE, and the nRF51 will relay them over UART to a terminal on the PC. Or you can send characters from the PC to the nRF51 over UART, and the nRF51 will replay them over BLE to the app. See this tutorial for more information.

It works, Thank you.

Sorry for asking again. I'm testing with application, nRF UART v2.0. With this app, phone can transmit characters such as "hello" but receive nothing. Isn't it loopback example? What should I do?

You need to use a SoftDevice that is compatible with the SDK. You should try to download SDK 11 from here. Then flash the S130 SoftDevice found in \components\softdevice\s130\hex and then the application.

I have tried but was frustrated. In 'Program Softdevice' tab in NRFGo, I downloaded 's130_nrf51_2.0.0-7.alpha_softdevice.hex' file. It was successful. After that I selected 'Program Application' tab, and tried to download 'nrf51422_xxac_s130.hex' but it failed. NRFGO said the reason as 'hex has data in Softdevice region'.

So I believed application file is nesting a softdevice region. And then I erased all of flash and tried to download by copying 'nrf51422_xxac_s130.hex' file to the PCA10028 folder. But my phone couldn't find this device.

It's my current situation.

Have you flashed the SoftDevice?
