Softdevice - NVS non volatile storage implementation.

[Neeraj Dhekale]

Hello,

I am new to Nordic. I was trying to find a sample code that has implemented NVS / EEPROM (I don't want to use external EEPROM). But I did not find any example that has this. I had implemented NVS earlier in Zephyr but in softdevice I am seeking help.

Please help. Thanks in advance.

Thanks and regards,

Hello Hung Bui,

I have checked by calling function flash_test before BLE stack then it works fine. but when I try to call after advertising start still I am getting error.

Thanks and regards,

Hello Hung Bui,

Can you please send me the below Section placement Micros? or else can you send your complete project?

Hi Neeraj, 

Did you test the code inside ble_app_hrs ? 
Please make sure that the nrf_fstorage_sd.c backend is used, not nrf_fstorage_nvmc.c file.

I attached here my project that you can test. Please note that the logging in on UART; not on RTT.

Hello Hung Bui,

Thank you very much for the code.

It is getting built successfully but it is not printing anything on UART. So I am not able to check.

I have attached a screenshot for your reference.

UART Properties

What can be the issue? I have posted this question for UART but still facing issues with UART. Standard UART example works well without any issue, but when I was trying to implement it on my own it was not working. So that's why I have posted this question regarding UART to know where and what I am doing wrong. 

Thanks and regards,

Hi Neeraj, 

You can verify if the flash got written or not by reading the flash. If you have the nrfjprog commandline tool you can use: 

nrfjprog.exe --memrd 0x5e000

I would suggest to test using a fresh copy of the SDK. And use an external UART terminal to test not the one comes with Segger Embedded Studio.
