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.

I don't see LED1 blinking only LED2 strong light and LED4 weak light.

When i debug, it can't jump into main function. So i don't know where is example execute.

it don't jump into main function, the debug functionality "Step F11"-"Step over F10"- "Step out(Ctrl+F10)",... is disable and can't execute when start press debug button

as I told you last time, if you are seeing LED4 half on and LED2 full on then you are in debug mode but haven't executed anything in the system init routine (which turns trace off). Have you even gotten a simple blinky example to work with no softdevice yet?

[Quangca]

Yes, i test all the sample without softdevice and all work very well. But when i test on softdevice fail

Thank you RK for your support. I solved.
