combining central and peripheral

[Henk Pragt]

Hi,

my application is normally a BLE scanner, listening for beacons. This runs OK.

Now, I tried to add a tested piece of connectable gap/gatt firmware, that runs fine in another application. The idea is to have the processor check a pushbutton at power-up. Normally the processor will call "sd_ble_gap_scan_start" to begin scanning, but if the button is pressed it calls the standard gap/gatt initialisation to start advertising:

  flash_timer_init();
  observer_init();
  gap_params_init();
  gatt_init();
  services_init();
  advertising_init();
  conn_params_init();
  peer_manager_init();

As I mentioned, this gap/gatt software works fine in another application, but here it crashes at the first call to "sd_ble_uuid_vs_add" with error_code 203995, which does not tell me how to fix it.

Is there possibly a conflict between central and peripheral, or a config setting that needs changing?

thx,

Henk

Hi,

203995 does not seem like an expected error code from sd_ble_uuid_vs_add, are you sure this is the correct error code?

Have you changed the sdk_config.h file (NRF_SDH_BLE_VS_UUID_COUNT) and project memory config to allow space for the vendor-specific UUID? 

Which SDK version are you using? Can you upload your project for us to reproduce and debug the error?

Best regards,
Jørgen

From the code you posted, it looks like you are not assigning the error code to the err_code variable. What you are seeing is most likely garbage from RAM. Please change your code to this:

err_code = sd_ble_uuid_vs_add(&base_uuid, &char_uuid.type);
APP_ERROR_CHECK(err_code);

Hi Jorgen,

I can't believe I missed that, shame on me ;-)

Thanks for your support,

Henk
