Add Characteristic to existing Service

[Inspectron]

I have the PCA 10028 Board. I would like to add a characteristic on an already existing service.

In the nAN-36 I see, what is necessary to set up service and characteristic.

In the LED Button application example there is one service with two characteristics.

UUID_Service 0x1523

UUID_LED_CHAR 0x1525

UUID_BUTTON_CHAR 0x1524

Now I added a characteristic:

UUID_PWM_CHAR 0x1526

I use the nRF Master Control Panel to write/read the value of the LED/BUTTON.

But the new service PWM with the UUID 1526 never appears in the list of the characteristic.

If I copy all this parts for the characteristic and paste it to the new characteristic(0x1526) should it then appear in the nRF Master Control Panel? Or is there something missing in the nAN-36? Is there another guide which one explains how need to set up Service and characteristic?

The project build and load with success. I did everthing step by step like it is explained in the nAN-36 guide.

Hi

There is a different version for the ble_app_lbs available here which contains two leds and two buttons. Perhaps you can take a look at that to see if you can spot something that is missing in your code. It is implemented for SDK 5.2.0 but the added code for the extra characteristics should be also be valid for more recent SDK's. To see exactly what is added to the code, you could compare the code with the original ble_app_lbs code on the SDK 5.2.0 branch.

Thank you! With your help I solved the problem. The initalization of the write handler was missing. Not it appears in the nRF Master Control Panel.
