NRF_ERROR_NO_MEM nrf52810, S112, SDK15

[Mikhail]

I have this error.

In a last time with same error on a nRF52832 I decided this problem with increase:

// <o> NRF_SDH_BLE_GATTS_ATTR_TAB_SIZE - Attribute Table size in bytes. The size must be a multiple of 4. 
#ifndef NRF_SDH_BLE_GATTS_ATTR_TAB_SIZE
//#define NRF_SDH_BLE_GATTS_ATTR_TAB_SIZE 1408
#define NRF_SDH_BLE_GATTS_ATTR_TAB_SIZE 2000
#endif

// <o> NRF_SDH_BLE_VS_UUID_COUNT - The number of vendor-specific UUIDs. 
#ifndef NRF_SDH_BLE_VS_UUID_COUNT
#define NRF_SDH_BLE_VS_UUID_COUNT 3
#endif

On the 52832 it works. But on the 52810- project fall. 

How to fix it?

May be should increase some memory?

Another problem- I can't tune RTT viewer for nrf52810.

Have you tried with the example: SDK15\examples\ble_peripheral\ble_app_uart\pca10040e\s112

And where exactly did you get the error NRF_ERROR_NO_MEM?

[Mikhail]

Yes, this example works. But in this example only one NUS service. It works. In the my project I have BAS and DIS services. And want to add third service- NUS. At this moment projectg fall with error- no memory.

 Is it one of the sd_...() calls that return NRF_ERROR_NO_MEMORY?

[Mikhail]

After call third service NUS.

And you can't get the log to work? Usually, the NRF_LOG will tell you what memory settings you should set. Do you use SDK15.0.0?

It is the function nrf_sdh_ble_enable() in nrf_sdh_ble.c that says what RAM settings you should set. What happens when you try to monitor the log? 

If you can't get the log to work, you can try to call ram_end_address_get() (and see what it returns). and check the *p_app_ram_start to calculate the RAM start and size.

RAM Start = p_app_ram_start (the content, not the pointer itself)

RAM Size = ram_end_address_get() - p_app_ram_start (again, the value, not the pointer itself).

Thanks. With RTT log in this project I have problems- doesn't work. In the another project- 52832- it works.

When I run RTT- only black window- no any information.

I'll try to check memory returned address.

What IDE do you use? If you use SES and you are debugging, the RTT log is printed in the IDE. 

Do you have any log processing in your main-loop? Most examples have. Did you remove it?

Try to get back to a working state (by only adding two "NUS" services), and check that the log is working here before you move on. 

[Mikhail]

I think- no errors in the RAM allocation. I still can't to run RTT viewer. 

[Mikhail]

Seems, RTT works.

But as screen above, no instructions to change memory. Error after try to init third sevice- NUS.

The screenshot shows you that the error was checked at line 287 in nus.c - which is the APP_ERROR_CHECK.

So put a breakpoint just before the call to ble_nus_init(), step into that function - and see where, exactly, the error occurs and what causes it ...
