Can't interface nRF52 preview DK with nRF Toolbox-UART iOS app

[Quangca]

dear everyone!

I order a kit- nRF52 preview DK: www.nordicsemi.com/.../nRF52-Preview-DK

And i also download nRF52_SDK_0.9.1_3639cc9.zip: developer.nordicsemi.com/.../

• The first i rebuild and download: ble_app_uart project to the board. And i see that LED2 turn on, LED4 is light but weak.

You can see the project at the location when you extract nRF52_SDK_0.9.1_3639cc9.zip ....\nRF52_SDK_0.9.1_3639cc9\examples\ble_peripheral\ble_app_uart

• Then i run Termite tool with RTS/CTS in setting, i also turn on RTS signal

• And the last i open nRF ToolBox-UART iOS app on my iPhone

nRF ToolBox can't detect the nRF52 preview DK. Can anyone show me how to solve it. I tried to find information on devzone but find nothing :(

When i open ble_app_uart project i see that have nrf52832_xxaa_s132 and s132_nrf52_1.0.0-3.alpha_softdevice in select target dropt box. So i need to work on what option.

Tested it on IOS 8.4(12H143) nrf Tools->UART with the application you mentioned and it works just fine.
