The service number displayed on Lightblue(one cellphone app)

Hi,

I'm learning the ble example, named ble_app_peripheral. When running the hex image, from the cellphone app, such as Lightblue, it displays there are 2 services. When i enable bass service, still showing 2 services ，but actually there are 3 services.

How to correct it?

Best regards

Fei

Hi feitian0409,

Hi feitian0409,

If I am not mistaken, you are trying to include the BASS profile in the ble_app_peripheral SDK5.0.4 example, aren’t you? The prox_reporter example of the SDK includes the Battery Service. Please check this example

  1. Add the bass.c and bass_task.h files in sdk_profiles folder. Both of them are located under sdk\ble_stack\profiles\bas\bass\src SDK folder path
  2. Add the appropriate header files which are under sdk\ble_stack\profiles\bas\bass path.
  3. #define EXCLUDE_DLG_BASS (0) in user_modules_config.h
  4. Add in user_callback_config.h the user_app_bass_cb as is in prox_reporter project.

Thanks, PM_Dialog

Hi，

Hi，

有一个错误,也许我don't express clearly.

I have enable the BASS profile successfully, and i can use the cellphone app "LightBlue" to see some informations.

But before and after that, the cellphone app still show two services, although there are actually three.

Please browse the attachment .

Best Regards,

Fei

Hi feitian0409,

Hi feitian0409,

My apologies but now I understood which your issue is. Alright, you should include the BASS into the advertising data. The default advertising data in the ble_app_peripherals example are the following:

#define USER_ADVERTISE_DATA ("\x03"\ ADV_TYPE_COMPLETE_LIST_16BIT_SERVICE_IDS\ ADV_UUID_DEVICE_INFORMATION_SERVICE\ "\x11"\ ADV_TYPE_COMPLETE_LIST_128BIT_SERVICE_IDS\ "\x2F\x2A\x93\xA6\xBD\xD8\x41\x52\xAC\x0B\x10\x99\x2E\xC6\xFE\xED")

You should add the Battery service and modify them as follow:

#define USER_ADVERTISE_DATA ("\x05"\ ADV_TYPE_COMPLETE_LIST_16BIT_SERVICE_IDS\ ADV_UUID_DEVICE_INFORMATION_SERVICE\ ADV_UUID_BATTERY_SERVICE\ "\x11"\ ADV_TYPE_COMPLETE_LIST_128BIT_SERVICE_IDS\ "\x2F\x2A\x93\xA6\xBD\xD8\x41\x52\xAC\x0B\x10\x99\x2E\xC6\xFE\xED")

Please let me know if this is working fine.

Thanks, PM_Dialog
