Hi,

Can you:

Post your code (I can make the case private first if you prefer it).
Re-build the program in debug mode and re-flash the code to your device. Is the log more verbose now? Does it detail where it asserts?

To rebuild your code in debug mode in SES, change from Release to Debug in upper left corner:

Yes it has. Can the problem occur because I’m initializing uart but don’t use uart pins on my custom board?

Hi there,

Does your custom board have an external low frequency crystal?

I think that it goes wrong by buttons_leds_init. But I don't know if I'm debugging in the right way.

If I run it in debug mode I do get this.

<info> app_timer: RTC: initialized.
<error> app: Fatal error

Hi,

Is the program actually reporting any specific errors except for the LED not blinking as you expected? Have you checked the log?

I think it is a problem with the UART. Do you know what the problem might be? It gets stuck by the UART initialization.

I didn't connect with any device. I think it is some other problem

Hi,

LED1 in ble_app_uart will only blink during advertising, once it has connected it will stop blinking. Have you checked the log whether a CONNECTED event has been generated?

I tried the basic ble_app_uart, programming goes fine but it doesn't work right the connection LED stays on instead of blinking. Do you know why this is?

Blinky does work fine.

Exactly what issues? Please specify.

[quote user="Juniorprogrammer"]So you refer to start a new project and put the code inside?[/quote]

Yes, that would probably be the easiest approach.

The code worked fine for the DK, but I have some issues on the custom board. So you refer to start a new project and put the code inside?

Hi,

[quote user=""]I did read I have to change some settings to program it on the nrf52811 on Nordic Semiconductor Infocenter. Do I have to use the folder of pca10056e?[/quote]

Yes, it's much easier to start with a PCA10056e project and then add the code into that project since it's already configured for the nRF52811.

The S112 is the Softdevice that we recommend using for nRF52811. It should be ok as long as you're using features that is supported by S112.
