ok i've found in sdk13 with sd_ble_cfg_set(BLE_COMMON_CFG_VS_UUID, &ble_cfg2, ram_start);

I'm using SDK13 and SDK9, and it's not there, I guess the config is somewhere else

Hi,

That parameter is there in softdevice_enable_get_default_config () which is present in softdevice_handler.c

I'm using SDK11 S130 PCA10028.

this line is not in softdevice_handler.c provided with SDK, can you be more precise? It's nowhere in the project.

You can advertise multiple services with 128-bit UUID by changing following parameter:

p_ble_enable_params->common_enable_params.vs_uuid_count = 1; in softdevice_handler.c

Change 1 to any number, i.e number of 128 bit UUID services you got.

How exactly do you switch out services?

RE: project with NUS prevents DFU from advertising

The solution is you cant advertise to 32byte uuid's in the advertising packet. I got around this by removing all the dfu stuff from my main app, and adding a special write charac to the BAS Battery level. When I write a magic number to the charac, it sets NRF_POWER->GPREGRET = BOOTLOADER_DFU_START, prepare for reset, then NVIC_SystemReset(). This will reboot the device into the bootloader which will require mobile app to reconnect, but it works seamlessly to the user.

Is there a solution? I have the same problem (NRF51 gcc). I see then DFU when i set the nus UUID to BLE_UUID_TYPE_BLE instead of BLE_UUID_TYPE_VENDOR_BEGIN. I tried to "fix' it on the android side: public static final UUID RX_SERVICE_UUID = UUID.fromString("6e400001-b5a3-f393-e0a9-e50e24dcca9e"); I cannot find the string for the modified UUID. Where can i find this?

I believe I found the answer... you cant advertise two 128-bit UUID and all the other services I need. I got around this by controlling which services are advertised. When I need to use the bootloader, I switch out the NUS service and advertise the bootloader instead.

Richard, can you please attach the project when you had error with two 128-bit UUID, i can take a look at it. Want to understand more and can give you proper answer.

You may have something. I changed the NUS service UUID to that of a 16bit one and now the new service name appears as well as the DFU. I could refine the my new NUS service more but would just like a real fix to the problem.

Hi, I am also facing the same problem, I think if try to added two services with 128 bit uuid the second one is not initialize successfully but with combination of one 128 bit uuid service and multiple 16 bit uuid services it advertising properly. could any one known the answer?

RE: project with NUS prevents DFU from advertising

To be clear, I simply took the example from examples\ble_peripheral\ble_app_hrs\pca10036\s132_with_dfu\arm5_no_packs, added the NUS service, and the service does not get discovered. I can remove the DFU init from services_init and the NUS is now discovered. SO, when probably should be more correct and say the service is not discovered (which I assumed related to advertising).

It is not possible that the program is not stuck and still not advertising. Which part of advertising are you talking now, is it NUS advertiser or DFU advertiser that is not working?

RE: project with NUS prevents DFU from advertising

Richard — Wed, 03 Feb 2016 00:15:20 GMT

I started looking at the example app (hrms w/ dfu). I added NUS service to this example and it will not advertise it. only the DFU comes up. No errors are generated!!!!

I was sure I checked this, but it turns out I was wrong. The NUS service is failing on the call to sd_ble_uuid_vs_add with a NRF_ERROR_NO_MEM error. Now where do I go?

You have to debug your application to see why it is not advertising, i am guessing that some condition fails and your system is restarting. Please follow this to see if your NUS app is asserting with APP_ERROR_CHECK
