[quote userid="7377" url="~/f/nordic-q-a/40055/bluetooth-not-connecting-after-inclusion-of-uart-module-in-hid-example-its-urgent/203959"] I suggest you create a new question for that since it is not related to the original question [/quote]

Indeed.

And, if the original question is now resolved, then verify the answer:

Sounds good. Then I suggest you create a new question for that since it is not related to the original question in this thread.

I figured out that I don't need to put NUS Service in the advertising packet. Now I just need to figure out how to discover the service after the peripheral device is paired with the central.

I am guessing that my advertising packet is too large with the HID service and the NUS service. How to work within these parameters?

Debug. Game changer. I have adjusted the RAM start and RAM size as per info in the Debug Terminal. I am still snagged however:

<error> app: ERROR 7 [NRF_ERROR_INVALID_PARAM] which takes me to:

err_code = ble_advertising_init(&m_advertising, &init);

Top Notch!

Today is a new day. Thank you for the direction. I will give it a go and report back.

Hi,

As awneil wrote to bscdb, you need to debug the issue to understand what is going on first. Since you use SES, you should start by selecting the Debug build configuration in the dropdown usually located in the upper left of the screen. That will turn off optimization and define DEBUG. Then you should observe the log output (UART or RTT), and this will tell you if an error has been detected, and if so, where and with what error code. This is always the first step.

Without seeing the error message, we can only guess, but generally, you need to adjust the memory configuration of the SoftDevice if you add more services, since it will need more RAM. It might be that you need to increase NRF_SDH_BLE_GATTS_ATTR_TAB_SIZE or NRF_SDH_BLE_VS_UUID_COUNT in your projects sdk_config.h. Debugging will tell you which of these. Note that if you do, you also have to adjust the application RAM start address and size, since the SoftDevice RAM usage increases.

I am having the same struggle. When I add

static ble_uuid_t m_adv_uuids[] = {{BLE_UUID_NUS_SERVICE, NUS_SERVICE_UUID_TYPE}};

to the HID example it crashes things immediately. I understand that the HID is a 16 bit UUID and the NUS_SERVICE is a 32 bit UUID.

I haven't figured out how to understand the error codes at this point. It is really frustrating. I followed the basic debugging tutorial but I keep getting a break point with a question mark? I am not sure where I turn optimization off at, I have tried to find it. I have been scouring these tutorials and posts but no luck piecing it together as of yet.

Have you found a solution for this yet?

Indeed - so have you done it?

what have you found?

I think thats a general approach which everyone follows!

you need to find the problem before you can solve it.

May be you can suggest some solution!

So what debugging have you done to find where it's failing?
