How to add more than one custom service.

[Leonan Fraga Leonardo]

Hi! 

I'm trying to implement my own service, which is based on Thingy TCS and another one I implemented by following this tutorial. https://github.com/bjornspockeli/custom_ble_service_example.

I'm new to developing BLE solutions.

I do these things:

• Create a new Custom Service
• Add new Characteristics
• Add the new CUSTOM_SERV_UUID to advertising array in main.c
• Set NRF_SDH_BLE_VS_UUID_COUNT to 2 inside the sdk_config.h
• Initialize service.
• Set NRD_SDH_BLE_GATTS_ATTR_TAB_SIZE to 2000, instead of 1408, inside the sdk_config.h.

But when I try to run, my application stops to do advertising. My application crashes when executing this code, inside the ble_wcs_init function, which is inside  in ble_wcs.c:

err_code = sd_ble_uuid_vs_add(&wcs_base_uuid, &p_wcs->uuid_type);

And after this, the error 4 is returned from sd_ble_uuid_vs_add() function.

I think I have two possible errors:
1 - I need to set the RAM_START and RAM_SIZE values. But how can I find a correct value from RAM_SIZE?
2 - When I created my new service, I put this in an advertising package and this made it exceed the allowed 31-byte value of advertising, one option is to configure advertising packet to scan response packet. But I do not want to do this, because my own "TCS" service does not need to be inside the ad packet.

Could anyone help me to solve this issue?

Ps: Sorry for my English and my question.

I think my problem was three things.

1 - I was setting a UUID in advertising that was actually overloading the maximum size of 31 bytes, I removed the service from the advertising package. Staying like this:
 
  static ble_uuid_t m_adv_uuids [] = / ** <Universally unique service identifiers. * /
   {
       {BLE_UUID_WCS_SERVICE, BLE_UUID_TYPE_BLE}
   };

2 - My BASE UUIDs were different for services, I believe this could be causing the problem, but I do not have enough knowledge to confirm this.

3 - I did not have to change the values of RAM_SIZE and RAM_START_ADDRESS, since they were already correct.
