NRF51822 add new service ，can not search for  the  ble   ，when i close this service in the service init function  ，it will go back to the normal。

[awneil]

liuzichen said:

can not search for  the  ble

What, exactly, do you mean by that?

The searching is done by the Central - it is entirely independent of anything that you do in your peripheral.

Did you also change something in the Central?

Perhaps your Central is configured to only "see" certain specific advertisements - so your change means that your advertisements are no longer "seen" by it.

Or (perhaps most likely?) your peripheral is just not advertising at all.

[liuzichen]

I also added the dispatch function，Does it really need to be set

[liuzichen]

now  i have known the error code andwhere it is

[liuzichen]

but i do not know how to slove it

[liuzichen]

[liuzichen]

the error lie in here

[awneil]

So the error code ahs come from ble_nus_init().

So step into that function, and see where that error code is generated.

not as an image, please.

So looking at your screenshot:

This means that the error occurs in main.c, the error code is 0x04, which I can find from nrf_error.h is NRF_ERROR_NO_MEM, and the line number is 0x014F (=line 335 decimal). 

From you other screenshot it seems this is caused by ble_nus_init(). If you now can help tell me which nRF5 SDK you are using, then I can try to take a look into ble_nus_init() and speculate what may cause this. You may also set breakpoints yourself into ble_nus_init() to find this if you want to.

[liuzichen]

please tell me how to know which sdk it is

[Kenneth]

Sorry, but don't you know which SDK you are working with?

I would assume it's one of these:
http://developer.nordicsemi.com/nRF5_SDK/ 

[liuzichen]

it is the sdk 11
