nrf51822 s120 Multi-link add s110 ble_uart NUS service doesn't work ?

[Greed]

Hi,

As title , I try to add the NUS service that show on the ble_app_uart project into Multi-link project. But it doesn't work .

I want to a central connected to at least two peripheral.what should I do ? the Operation is under SDK10 & s120 .

Thanks .

After changing the program ,I can find the NUS service.Thanks.

But I still have some problems. First , I can't connect it ,so i add the "ble_conn_params.h" and something setting. After this operation , I can connect it . Second, Rx service can be used , but Tx service are not lucky.

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

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.
