Hi,

You will need to look at the call stack to find where the error is coming from. In the debugger, open the p_error_info and find the value of err_code...

Hi,

sorry for the late reply, i placed the breakpoint in ble_nus_init() but the LED error show nothing

void services_init(void)
{
    uint32_t       err_code;
    ble_nus_init_t nus_init;

    memset(&nus_init, 0, sizeof(nus_init));

    nus_init.data_handler = nus_data_handler;


    err_code = ble_nus_init(&m_nus, &nus_init);
	Err::signalWithCode(err_code,6);
}

problem is if i debug it the device can be found but the code goes direct to NRF_BREAKPOINT_COND;

but if i only flash and run the device could not be found at all.

best regards,

Andhika

Hi,

Do you call ble_nus_init() in service_init()? If yes, place a breakpoint in the code line right under it, so for example if you have:

err_code = ble_nus_init(&m_nus, &nus_init);
APP_ERROR_CHECK(err-code);

Try sending a breakpoint at the APP_ERROR_CHECK line. Then check the value you get in err_code.

Hi,

Sorry for the late reply. Have you increased NRF_SDH_BLE_VS_UUID_COUNT from 0 to 1 in sdk_config.h?

Hi,

thanks for your reply, and yes NRF_LOG_ENABLED is set to 1. bu as I debug the program my code stop at service_init the program didn't go through this and go to NRF_BREAKPOINT_COND instead.

i did exactlc like tutorial.

Hi,

Sorry for the late reply. Do you get any error messages in nrf_log when this happens? Remember to set NRF_LOG_ENABLED to 1 in sdk_config.h

Hi majeris,

thanks for getting back, sorry for late reply I had exam yesterday

it has no error it just the bluetooth device could not be found anymore (the deivce name and it's service doesn't appear)

thanks for your link to the tutorial custom service i'll able to keep a track, I already compare it and follow it step by step. but still my device could not be found

previously I hv similar issue when i tried modify the ram, my device could not be found but when I reset to the orginal ram it appear again, and yeterday i tried to change the ram like the tutorial suggest but didn't work. Is it possible that the root of these issues lies on ram?

here is the original ram it's bigger then the ram that suggested

MEMORY
{
  FLASH (rx) : ORIGIN = 0x26000, LENGTH = 0x5a000
  RAM (rwx) :  ORIGIN = 0x20002b88, LENGTH = 0x3d478
}

best regards,

Andhika

Hi,

What error message are you getting now? Have you tried to compare your application to ble_app_uart?

In ble_app_template the function advertising_init is called before service_init(). If you want to advertise the NUS UUID you need to change the order and call advertising_init() after services_init().

Best regards,

Hi,

[quote userid="73427" url="~/f/nordic-q-a/56812/device-could-not-be-found-due-to-changes-in-m_adv_uuids/230403"]How have you defined BLE_UUID_NUS_SERVICE? Did you include ble_nus.h in your project? Please take a look at the ble_app_uart example. This example runs the Nordic UART Service (NUS) and can be found under 'examples/ble_peripheral/ble_app_uart' folder.[/quote]

yes I defined it through ble_nus.h i already included it in makefile and yes i took the example for my project from ble_app_uart.

yeah i also aready defined BLE_UUID_TYPE_VENDOR_BEGIN in nus_service_uuid_type this one that cause the problem i think.

The Nordic UART service is a custom service, so we use a 128-bit vendor specific UUID and you need to use UUID type BLE_UUID_TYPE_VENDOR_BEGIN.

You can change the base of the 128-bit vendor-specific UUID by changing NUS_BASE_UUID in ble_nus.c if you want (for example if you want to create a custom UART service for your application), please take a look a this tutorial for more information about custom services and UUIDs.
