how to add ble_dis_on_db_disc_evt(),dis_c_evt_handler() functions to get Device information service when central scans and connected?

[sankeerthan]

i am using ble_app_hrs_c_pca10056_s140 and when connected to one particular device i am able to get battery level of advertiser but i what advertiser's device information service like it's model number,firmware version etc..,characteristics.

I am uable to find any DIS related files in ble_app_hrs_c_pca10056_s140 and i enabled BLE_DIS_ENABLED but no result.

Please suggest me where and what modification i need to do.

Thankyou.

The SDK does not implement a DIS client, so you would have to implement this yourself.

If you have specific questions or problems, please let me know.

ok,Can you Explain in short how to implement a DIS client or suggest any document to do it,Are the given ble_dis files in ble services can be used only for advertising?

I would suggest to look at how HRS client (ble_hrs_c) is implemented.

The DIS service only contains characteristics that should be read, so you only need to use sd_ble_gattc_read(uint16_t conn_handle, uint16_t handle, uint16_t offset).

The handles are usually discovered by using service discovery (you can use the discovery module), or can be hardcoded if you know the layout of the attribute table.

Hi,As per your suggestion i have modified BAS client(ble_bas_c) and it is working fine for DIS service after changing battery service UUID with BLE_UUID_DEVICE_INFORMATION_SERVICE and character of battery level with BLE_UUID_MODEL_NUMBER_STRING_CHAR and i have also changed structure to store data of DIS with battery level but problem is in ble_bas_on_db_disc_evt() i am able to get only one Characteristic data because it's cccd value is only assigned.In DIS i have 6 Characteristics how can i get and print all Characteristics data(i.e i need to handle all cccd values).

Please suggest me where can i do necessary modifications.

Thank you

The characteristics in the DIS service doesn't support notify, they only support read. You have to use sd_ble_gattc_read()
