Thanks. I solved the problem of service. But I still have some problems. By the way , if I want to do a project following. The central that has NUS service can connect to at least two peripheral . Two peripheral also have NUS service. So , What am i to do in ble_app_multilink_central project? does it Such as add a NUS service into the ble_app_multilink_peripheral project? Thanks.

It does not stop at power_manage, it waits for an application event.

Anyways, I had a look at your application.

In advertising_init() you are adding the NUS UUID to scanrsp struct, but you are not providing it to ble_advertising_init(&advdata, NULL, &options, on_adv_evt, NULL);

I changed this to

err_code = ble_advertising_init(&advdata, &scanrsp, &options, on_adv_evt, NULL);

But this returns the 0x00000007 error, NRF_ERROR_INVALID_PARAM.

This is because you are giving it an UUID type that we haven't added to the stack with sd_ble_uuid_vs_add(), this is giving to the stack in services_init(), which is called after advertising_init(). Change the order of services_init() and advertising_init() and see if you get the result you want.

I updated some information . I think that my project and ble_app_uart project stop at power_manger in debug mode. Thanks.

Then you have probably gotten a returned error somewhere. Have you used to the debugger? If you put a breakpoint on ble_advertising_start(), are you hitting it? If you want me to take a look at your code, please zip your complete project and upload it.

Hi, First, If the central isn't be connected to the power , I can see the peripheral on the phone. When central is connected to the power , I can't see the peripheral on the phone. So , I can sure that ble_app_multilink_peripheral & ble_app_multilink_central are working.

Second I try to add the NUS service into ble_app_multilink_peripheral project that like files above. It also can do ble_app_multilink_peripheral & ble_app_multilink_central are working. But i can't see NUS service on the phone.

By the way "main.c" is the project that I try to add the NUS service . "modify.txt" is the code which I modify or add.

Thank.

So you have started off ble_app_multilink_peripheral? And you have tried to add the NUS service to this example? How have you added it? What is it that doesn't work? You need to provide some more information.

I can use Iphone to find the peripheral before adding the NUS service into Multi-link project. When added the NUS service, I can't find it .
