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. 

[Mikhail]

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 ...

[Mikhail]

ok, wait.

Since you only mention "SDK15", I will refer to line numbers from SDK15.0.0. If you use another version, you should be able to find it, but the line numbers may vary.

If you look in ble.h on line 492 you can see the possible return values for sd_ble_uuid_vs_add(). On line 490 it states that it will return NRF_ERROR_NO_MEM if there are no more free slots for VS UUIDs. 

You can find all these sd function call descriptions in the SDK. Just search for the function name, and look for the one with SVCALL(...

So try to increase NRF_SDH_BLE_VS_UUID_COUNT on line 8726 in sdk_config.h. Note that changing this may also trigger the project to require more RAM. Look for it in the log.

[Mikhail]

Yes, version is nRF5 SDK v15.0.0

Release Date: Week 12, 2018

Yes, works. Thanks. Problem was in the not worked RTT. Now RTT is works and I can see all messages. I tune like RTT writed and now it works. Thanks.
