I want to know how to set Service and Characteristics anew with BLE sample.

[hitsato]

We use nRF 5 SDK v 15.2.0.

We want to realize BLE using samples.

qiita.com/.../7c448837eedf439b8ee9
In sdk15.2.0, there is no sample called "ble_sdk_app_nus_eval".

Since there was "ble_app_uart", this program is used as a reference.

I executed this program, I used "nRF Connect" on my smartphone and made a CONNECT.

In the Service screen, UUID = 6E400001-B5A3-F393-E0A9-E50E24DCCA9E is displayed.

Once selected, on the Characteristics screen
RX = 6E400002-B5A3-F393-E0A9-E50E24DCCA9E
TX = 6E400003-B5A3-F393-E0A9-E50E24DCCA9E
Was displayed.

As a specification of this development,
Service Name: UUID 1111 (00001111-0000-0000-0000-000000000000)
Characteristics Name: Param 2222, value 0x03
I want to send and receive BLE data in, but how should I customize the sample,
I do not understand.

Please teach us the sample customization.

We apologize for the inconvenience, but thank you.

Sorry for the late reply.

Downloaded and performed debugging with SEGGER.

Failed to set startup completion breakpoint: main symbol not found
Failed to set initial breakpoint: main symbol not found
I got an error and was unable to get it to work.
Is there a setup error?
