Even I was having the same issue. Thanks for the solution.

We modified the count to 2 as we have 2 custom services, however the nrf gets stuck in softdevice_enable(&ble_enable_params) function. How do we resolve this issue? Is it due to RAM size?

@hkartadi Are you able to solve your issue? I have same issue and error is "NRF_ERROR_NO_MEM", The custom service is really tiny - only one characteristic.

Maybe good for the migration document. Although a logical thing to look for if you get a NRF_ERROR_NO_MEM, it's still nice to know that this needs to be set now.

I was having the same issue that the original poster described and this solved my problem. Thanks!

Hi, You need to modify number of custom UUIDs, which can be added. Change the following parameter: p_ble_enable_params->common_enable_params.vs_uuid_count = 1; from 1 to a number of custom services you want to have. Look into the softdevice_handler.c file.

Well I'll give you the same advice. Put a breakpoint in the error handler. Boards don't just disappear into the sunset, or stop working and they don't get all upset and just stop advertising because they don't feel like it. The processor is somewhere doing something, hit break and find out where and what.

I also have the same issue, basically I modified a example of heart rate monitor with adding custom 128bit uuid service (I removed all standard 16-bit UUID services). The board works and advertising that 128bit. However, when I enable the Over the air DFU defined which is by default using different 128bit UUID. The board does not work anymore - no led to indicate anything that probably means the code doesnt even execute to main while loop.

Then, if I comment out my custom 128bit UUID and enable just the 128bit DFU services. The board works and advertise!. Does it mean only 1 base 128bit UUID can be used? or other workaround I can try?

Usual advice - put a breakpoint in the app error handler because that's most likely where you went after a function returned an error. And most likely you went there because the advertising encoder returned an error code because there's no room in the advertising packet for a long custom UUID along with all the other stuff which is already in there. Put it in the scan response.

Again: what S132 version is it? In the alpha releases of the S132 e.g. there is a bug causing sd_ble_uuid_vs_add() to return NRF_ERROR_NO_MEM if you try to call it twice or more with the same UUID. Have you tried stepping through your code and looked for asserts? Here is a guide on how to look for asserts.

Hi. What S132 version are you using and how exactly are you trying to add more services? Could you post your code?
