Can you post the working 'final' code if you have it ?

Thanks for your reply. The project is working fine now.

Hello,

Took a look at your project. It says that it fails on line 181 in main.c (as it says in the log output that you attached).

Now that I had your main.c I see that you commented outt line 177, err_code = app_uart_put(...);

This means that the APP_ERROR_CHECK(err_code); will use the err_code with the value from it's declaration on line 166:

uint32_t err_code;

So it is set to a random value (whatever was on that address in the RAM from before), not necessarily 0.

To fix this, either comment in the err_code = app_uart_put(...);

or change the declaration on line 166:

uint32_t err_code = NRF_SUCCESS;

Of if you don't intend to print the data on the physical UART at all, you can remove the app_uart_put(...); and the APP_ERROR_CHECK(err_code) on line 181 as well.

Best regards,

Edvin

Yes, sorry for not making my point clear. I still stuck with the problem I updated at 9 PM.

So do you still get the NRF_ERROR_NO_MEM message? Not sure when you updated the original question (don't know what timezone you are in), but the last log window you posted describes another error code.

Error 0x20005732. Is that the error you are currently stuck with?

BR,

No. 『Insufficient RAM allocated for Softdevice 』message hasn't shown since I adjusted RAM allocation .

Do you still get the "Insufficient RAM allocation for the SoftDevice" message?

Unfortunately , No, I still got the same problem. Is there any other suggestion??

Do you still get the NRF_ERROR_NO_MEM after you changed the RAM settings?

BR,

If the UUID count is adjusted, the suggestions by the SoftDevice should be okay.

Hi Andre

Thanks for your reply.

I have adjusted the RAM Base and size by the suggestion which Softdevice hinted me. Do I still have to adjust it?

and here are RAM Base and size of my project

I don't exactly know how to do this in Keil, but you'll probably need to adjust your linker settings. Raise the start of application ram address, to give the soft device more ram.
