![]() To ensure that the entire LOCAL_NAME is available during advertising, Anki Drive vehicles only use up to 20 bytes of LOCAL NAME data. However, Bluetooth LE devices may only advertise up to 20 bytes of the LOCAL NAME data ( Bluetooth 4.0, Part C, 11.1.2). The Bluetooth 4.0 specification requires that the LOCAL_NAME field be a UTF-8 encoded string of up to 248 bytes, with shorter values terminated by a NULL (0x0) byte ( Bluetooth 4.0, Part C, 3.2.2.3, 12.1). * - product_id: Value identifying the vehicle as Anki Drive hardware * - model_id: The model type of a vehicle * - identifier: Unique identifier for a physical vehicle * Vehicle hardware information encoded in the MANUFACTURER_DATA This value specifies the 'make/model' of the vehicle ( model_id) and a unique identifier for each vehicle of the specified model ( identifier). The manufacturer data is a uint64_t value that uniquely identifies each vehicle. This UUID can be used to identify vehicles during scanning, or as a handle to discover the read and write characteristics after connecting to a vehicle. The service_id for an Anki Drive vehicle is defined in the GATT profile for the vehicle, and will always be the same 128-bit UUID. * service_id: Anki Vehicle UUID (128-bit) * local_name: parsed data from the LOCAL_NAME string bytes * mfg_data: parsed data from the MANUFACTURER_DATA bytes * Vehicle information present in Bluetooth LE advertising packets. Vehicle advertisements consist of the Anki Drive service UUID ( service_id), along with a unique identifier ( mfg_data), name and state information ( local_name). The Anki Drive SDK provides methods to parse EIR data into records and toĮxtract vehicle information from specific types of records. These records types are defined as part of the GATT profile specification. If raw scan data from the Extended Inquiry Response (EIR) is available, it needs to be parsed to obtain the LOCAL_NAMEĪnd MANUFACTURER_DATA. On Linux and Android, the raw scan bytes are exposed via the bluetooth API ( BlueZ, Linux android.bluetooth, Android) and must be parsed to obtain the GATT profile data members of interest. On iOS, CoreBluetooth parses this data internally and provides an NSDictionary containing the profile data. Vehicles broadcast identifying information and service definitions in the form of advertising packets.Īn advertising packet contains binary data in a parsable format defined by a generic attribute profile (GATT).ĭepending on the bluetooth API available on the central, this information may be exposed in different ways. Once connected, a central device can communicate with vehicles using the Anki Drive message protocol outlined below. This document describes the format of the vehicle advertisement data, which can be used to decode the vehicle identifier, name and model. The protocol is conceptually similar to a client-server architecture, in which a client device (central) can connect to and communicate with a server device (peripheral).įor more information on Bluetooth 4.0, see the Bluetooth 4.0 Core specification.Īnki Drive vehicles are Bluetooth low energy peripheral (server) devices.Īny device capable of acting as a central (client), such as a smartphone or computer, can discover, connect to and control vehicles.Įach vehicle advertises identifying information and a service that consists of characteristics for sending and receiving data. Good luck fellas.The Bluetooth 4.0 specification defines a wireless communication protocol for use with low energy devices. Where nothing crashed, everything was working well, and no menu glitches occurred. before they reworked the campaign that is complete sh- anyways, if you guys can return the old Overdrive with even a new tournament menu layout, then I bet you can late tournament-stage Overdrive. But yet again, old Overdrive was basically like this for a little bit, but it picked itself back up. I tested with the other modes too and had the same results. Then when I opened up tournament mode, I hit the button that has the cars scan the track, then the game just immediately crashes. Instead, the little buttons on the bottom that say lines like, “Learn more about super cars” and such. When I opened the garage, the menu wouldn’t even come up. Yet of course, the older Overdrive as well had a lot of glitches. ![]() Everything is how I’d hoped it would come to. I will admit, sweet thinking bringing back the old Overdrive.
