SDK12 ble_app_buttonless_dfu

[Sergy]

Hi,

Im tryin to use the ble_dfu service example from SDK12, I get DFU SERVICE NOT FOUND when trying to update from Android. Any suggestions what to look for?

I use S132v3, bootloader is flashed and I performed successful upload of the application via BLE when there was no app loaded.

When I write 0x01 into characteristics we get into the following code:

static void on_rw_authorize_req(ble_dfu_t * p_dfu, ble_evt_t const * p_ble_evt)

{ if (p_ble_evt->evt.gatts_evt.conn_handle != p_dfu->conn_handle) { return; }

const ble_gatts_evt_rw_authorize_request_t * p_auth_req =
    &p_ble_evt->evt.gatts_evt.params.authorize_request;

if (
    (p_auth_req->type == BLE_GATTS_AUTHORIZE_TYPE_WRITE)
    &&
    (p_auth_req->request.write.handle == p_dfu->control_point_char.value_handle)
    &&
    (p_auth_req->request.write.op != BLE_GATTS_OP_PREP_WRITE_REQ)
    &&
    (p_auth_req->request.write.op != BLE_GATTS_OP_EXEC_WRITE_REQ_NOW)
    &&
    (p_auth_req->request.write.op != BLE_GATTS_OP_EXEC_WRITE_REQ_CANCEL)
   )
{
    on_ctrlpt_write(p_dfu, &p_auth_req->request.write);
}

}

and this condition fails: (p_auth_req->request.write.handle == p_dfu->control_point_char.value_handle)
