Carles now i can see characteristics the problem was with "p_sbs_init->notify_data.length" and "write_data.length" variable they where not getting filled because of that add char function was not getting called. Now by editting that i can see both my characteristics. Thanks for your support Carles !!!

Ok let me check

It is the SoftDevice who fills in these handles, so the value will be valid when you return from the _add() functions

The handles are in the variables I mentioned in the comment above. You only need to print them out on the UART

OK i will try with PC Version of Master control Panel even i have a ble sniffer but don't know why its not sniffing data from this device i did try that. Quite strange... How can i get those handles since i am passing that handles in Service add and Characteristics add routine function and in return i am just getting NRF_SUCESS or an Error code.

Honestly I'm not sure what else to suggest. Can you run the Nordic sniffer if you have an additional card with a Nordic IC on it to see the traffic? or maybe the log from the Master Control Panel (PC version) ? Something that gives us a bit more information. Also can you post the handles you get back for your service and the 2 characteristics? they should be in p_sbs->service_handle, write_handles and notify_data_handles

Yes they are different.. #define SMARTBEACON_UUID_SERVICE 0x9E83 #define BLE_UUID_WRITE 0xC203 #define BLE_UUID_NOTIFY_DATA 0xC201

And the 3 sub-UUIDs that you are using: SMARTBEACON_UUID_SERVICE, BLE_UUID_WRITE, BLE_UUID_NOTIFY_DATA, are they different numbers?

@Carles i tried both the ways, (1) i am getting NRF_SUCCESS for Characteristics adding routine (2) Even i tried to check with other phone and android app but no change.

@ Martin i tried by switching different ble apps even i restarted my android phone many times but not helping...

I am not sure if it is the case here, but sometimes the attribute table is cached on the phone. That means that you won't see the changes you make on the device side on your app. The way I usually solve this is closing the app, open another BLE app, then close this app again, and return to the first app. I also think you can turn on and off BLE on your phone and then restart the app.

I see nothing immediately wrong with the code, so there's only 2 things that I can suggest to check. First make absolutely sure that the calls to sd_ble_gatts_characteristic_add() are returning NRF_SUCCESS. Second, can you try with another app (Master Control Panel on the PC, or another Android app) to see if this might be an issue with the Android app itself.

Yes in Custom Service section i should get 2 Characteristics(WRITE/NOTIFY,READ). But they are missing any how. Irrespective of that other all things are seen correctly same as my sdk 6 devices.

So just to be clear, you can see the service (as shown in the screenshot) but not the characteristics, correct?
