Bonding Problem

[Muhammet YILDIZ]

Hello

I am trying to create secure connection between peripheral device and mobile app & central device.

I created my own custom service and want to make them secure.

But i am getting

app: ERROR 2 [NRF_ERROR_SOFTDEVICE_NOT_ENABLED] at ......\main.c:525

and this line is in this function:

How can fix this issue and what am i missing?

I am using nRF52832 and SD132

Here is my project file. ble_app_blinky.7z

can some one help? I still could not solve this problem

Which SDK and SoftDevice are you using? Did you start off with an example using Peer Manager? Do you have any logs showing what is going on?

You are getting PM_EVT_ERROR_UNEXPECTED? Have you tried to debug further to see where it originates from?

Also consider uploading your complete project so I can test it here. You can do it by editing your question and clicking the paper clip icon.

Hello Peter.

Which SDK and SoftDevice are you using?

I am using SD132, nRF5_SDK_14.2.0_17b948a, nRF52840.

Did you start off with an example using Peer Manager?

Yes i did. In fact i used ble_app_gls example.

Do you have any logs showing what is going on?

Here is my project definetions. DEBUG BOARD_PCA10040 CONFIG_GPIO_AS_PINRESET FLOAT_ABI_HARD NRF52 NRF52832_XXAA NRF52_PAN_74 NRF_SD_BLE_API_VERSION=5 S132 SOFTDEVICE_PRESENT SWI_DISABLE0

Here is my console log (i opened colored log);

[0m<info> app: First time boot[0m
[0m<info> app: --> Event received: wrote 44 bytes at address 0x3E000.[0m
[0m<info> app: Fast advertising[0m

[0m<info> app: Connected[0m
[1;31m<error> app: ERROR 2 [NRF_ERROR_SOFTDEVICE_NOT_ENABLED] at ..\..\..\main.c:548[0m

You are getting PM_EVT_ERROR_UNEXPECTED?

That is right. In the pm_evt_handler case

case PM_EVT_ERROR_UNEXPECTED:
{
    // Assert.
    APP_ERROR_CHECK(p_evt->params.error_unexpected.error);
} break;

Have you tried to debug further to see where it originates from?

I made some debug to see what is going on. But did not get much more info. In fact, i did not find explanation for this error code. Usally when i get an error code, i am looking for some explanation for that. And that helps me alot.But i did not find for this error.

Some how i got some feelings that i am getting this because my main loop is this;

// any pending write request?
		if( pending_write == true )
		{
			// clear write request
			pending_write = false;
			
			// write to flash and check for errors
			err_code = nrf_fstorage_write( &fstorage, APP_FLASH_START_ADDRESS, &config, sizeof( config_t ), NULL );
			APP_ERROR_CHECK( err_code );
		}
		
        if (NRF_LOG_PROCESS() == false)
        {
            power_manage();
        }

Am i feeling right?

Also consider uploading your complete project so I can test it here. You can do it by editing your question clicking the paper clip icon.

I guess this is best way. BTW i need docs to understand ble and nordic sdk. I may have a little confuse.

I still did not solve this problem. Can some one help a little?
