nRF52 DK kit can't run ble_app_template

[Nahan_Trogn]

Hi, I've got some issues:

I use nRF52 DK kit run "BLE Blinky Application", it work properly, yes.

And then, I want to dev my own program, so I buid from "ble_app_template". I compile the "ble_app_template" originally, but my kit didn't work (led 1 didn't flash and nRF Connect could not scan it). Arcoding to the guide on Nordic web,:

Test the Template Application with nRF Connect for Desktop by performing the following steps:

1. Compile and program the application. Observe that the BSP_INDICATE_ADVERTISING state is indicated.
2. Connect to the device from nRF Connect (the device is advertising as 'Nordic_Template'). Observe that the BSP_INDICATE_CONNECTED state is indicated.
3. Disconnect the device in nRF Connect and observe that the BSP_INDICATE_ADVERTISING state is indicated. You can wait for 3 minutes and observe that the BSP_INDICATE_IDLE is indicated.
4. In system-off, press Button 1 and observe that the application starts advertising again.

I dont know the reason why my kit run fail.

Thanks in advance, sorry for my English

Hi

What IDE/compiler do you use? Have you made sure that the SoftDevice is flashed onto the nRF52 DK as welll? Flashing the precompiled .hex file on my end does exactly what the test steps say. Have you editted the ble_app_template example at all on your end?

Best regards,

Simon

Hi, I use SEGGER Compiler on Ubuntu, so SoftDevice is loaded automatically. As I mention above, I can run BLE Blinky Application, which also need softdevice (s132)
