| </h1> |
| <p>This document describes the Spinel protocol, which facilitates the control and management of IPv6 network interfaces on devices where general purpose application processors offload network functions at their interfaces to network co-processors (NCP) connected by simple communication links like serial data channels. While initially developed to support Thread(R), Spinel's layered design allows it to be easily adapted to other similar network technologies. </p> |
| <p>This document also describes various Spinel specializations, including support for the Thread(R) low-power mesh network technology. </p> |

| <p id="rfc.section.1.p.1">Spinel is a host-controller protocol designed to enable interoperation over simple serial connections between general purpose device operating systems (OS) and network co-processors (NCP) for the purpose of controlling and managing their IPv6 network interfaces, achieving the following goals: </p> |
| <p/> |
| |
| <ul> |
| <li>Adopt a layered approach to the protocol design, allowing future support for other network protocols.</li> |
| <li>Minimize the number of required commands/methods by providing a rich, property-based API.</li> |
| <li>Support NCPs capable of being connected to more than one network at a time.</li> |
| <li>Gracefully handle the addition of new features and capabilities without necessarily breaking backward compatibility.</li> |
| <li>Be as minimal and light-weight as possible without unnecessarily sacrificing flexibility.</li> |
| </ul> |
| |
| <p> </p> |
| <p id="rfc.section.1.p.3">On top of this core framework, we define the properties and commands to enable various features and network protocols. </p> |
| <h1 id="rfc.section.1.1"><a href="#rfc.section.1.1">1.1.</a> <a href="#about-this-draft" id="about-this-draft">About this Draft</a></h1> |
| <p id="rfc.section.1.1.p.1">This document is currently in a draft status and is changing often. This section discusses some ideas for changes to the protocol that haven't yet been fully specified, as well as some of the impetus for the current design. </p> |
| <h1 id="rfc.section.1.1.1"><a href="#rfc.section.1.1.1">1.1.1.</a> <a href="#scope" id="scope">Scope</a></h1> |
| <p id="rfc.section.1.1.1.p.1">The eventual intent is to have two documents: A Spinel basis document which discusses the network-technology-agnostic mechanisms and a Thread(R) specialization document which describes all of the Thread(R)-specific implementation details. Currently, this document covers both. </p> |
| <h1 id="rfc.section.1.1.2"><a href="#rfc.section.1.1.2">1.1.2.</a> <a href="#renumbering" id="renumbering">Renumbering</a></h1> |
| <p id="rfc.section.1.1.2.p.1">Efforts are currently maintained to try to prevent overtly backward-incompatible changes to the existing protocol, but if you are implementing Spinel in your own products you should expect there to be at least one large renumbering event and major version number change before the standard is considered "baked". All changes will be clearly marked and documented to make such a transition as easy as possible. </p> |
| <p id="rfc.section.1.1.2.p.2">To allow conclusive detection of protocol (in)compatibility between the host and the NCP, the following commands and properties are already considered to be "baked" and will not change: </p> |
| <p/> |
| |
| <ul> |
| <li>Command IDs zero through eight. (Reset, No-op, and Property-Value Commands)</li> |
| <li>Property IDs zero through two. (Last status, Protocol Version, and NCP Version)</li> |
| </ul> |
| |
| <p> </p> |
| <p id="rfc.section.1.1.2.p.4">Renumbering would be undertaken in order to better organize the allocation of property IDs and capability IDs. One of the initial goals of this protocol was for it to be possible for a host or NCP to only implement properties with values less than 127 and for the NCP to still be usable---relegating all larger property values for extra features or other capabilities that aren't strictly necessary. This would allow simple implementations to avoid the need to implement support for PUIs (<a href="#packed-unsigned-integer">Section 3.2</a>). </p> |
| <p id="rfc.section.1.1.2.p.5">As time has gone by and the protocol has become more fleshed out, it has become clear that some of the initial allocations were inadequate and should be revisited if we want to try to achieve the original goal. </p> |
| <h1 id="rfc.section.2"><a href="#rfc.section.2">2.</a> <a href="#frame-format" id="frame-format">Frame Format</a></h1> |
| <p id="rfc.section.2.p.1">A frame is defined simply as the concatenation of </p> |
| <p/> |
| |
| <ul> |
| <li>A header byte</li> |
| <li>A command (up to three bytes, see <a href="#packed-unsigned-integer">Section 3.2</a> for format)</li> |
| <li>An optional command payload</li> |

| <p id="rfc.section.3.2.p.1">For certain types of integers, such command or property identifiers, usually have a value on the wire that is less than 127. However, in order to not preclude the use of values larger than 255, we would need to add an extra byte. Doing this would add an extra byte to the majority of instances, which can add up in terms of bandwidth. </p> |
| <p id="rfc.section.3.2.p.2">The packed unsigned integer format is based on the <a href="https://www.w3.org/TR/exi/#encodingUnsignedInteger">unsigned integer format in EXI</a>, except that we limit the maximum value to the largest value that can be encoded into three bytes(2,097,151). </p> |
| <p id="rfc.section.3.2.p.3">For all values less than 127, the packed form of the number is simply a single byte which directly represents the number. For values larger than 127, the following process is used to encode the value: </p> |
| <p/> |
| |
| <ol> |
| <li>The unsigned integer is broken up into <em>n</em> 7-bit chunks and placed into <em>n</em> octets, leaving the most significant bit of each octet unused.</li> |
| <li>Order the octets from least-significant to most-significant. (Little-endian)</li> |
| <li>Clear the most significant bit of the most significant octet. Set the least significant bit on all other octets.</li> |
| </ol> |
| |
| <p> </p> |
| <p id="rfc.section.3.2.p.5">Where <em>n</em> is the smallest number of 7-bit chunks you can use to represent the given value. </p> |
| <p id="rfc.section.3.2.p.6">Take the value 1337, for example: </p> |
| <pre> |
| 1337 => 0x0539 |
| => [39 0A] |
| => [B9 0A] |
| </pre> |
| <p id="rfc.section.3.2.p.7">To decode the value, you collect the 7-bit chunks until you find an octet with the most significant bit clear. </p> |
| <h1 id="rfc.section.3.3"><a href="#rfc.section.3.3">3.3.</a> <a href="#data-blobs" id="data-blobs">Data Blobs</a></h1> |
| <p id="rfc.section.3.3.p.1">There are two types for data blobs: <samp>d</samp> and <samp>D</samp>. </p> |
| <p/> |
| |
| <ul> |
| <li><samp>d</samp> has the length of the data (in bytes) prepended to the data (with the length encoded as type <samp>S</samp>). The size of the length field is not included in the length.</li> |
| <li><samp>D</samp> does not have a prepended length: the length of the data is implied by the bytes remaining to be parsed. It is an error for <samp>D</samp> to not be the last type in a type in a type signature.</li> |
| </ul> |
| |
| <p> </p> |
| <p id="rfc.section.3.3.p.3">This dichotomy allows for more efficient encoding by eliminating redundency. If the rest of the buffer is a data blob, encoding the length would be redundant because we already know how many bytes are in the rest of the buffer. </p> |
| <p id="rfc.section.3.3.p.4">In some cases we use <samp>d</samp> even if it is the last field in a type signature. We do this to allow for us to be able to append additional fields to the type signature if necessary in the future. This is usually the case with embedded structs, like in the scan results. </p> |
| <p id="rfc.section.3.3.p.5">For example, let's say we have a buffer that is encoded with the datatype signature of <samp>CLLD</samp>. In this case, it is pretty easy to tell where the start and end of the data blob is: the start is 9 bytes from the start of the buffer, and its length is the length of the buffer minus 9. (9 is the number of bytes taken up by a byte and two longs) </p> |
| <p id="rfc.section.3.3.p.6">The datatype signature <samp>CLLDU</samp> is illegal because we can't determine where the last field (a zero-terminated UTF8 string) starts. But the datatype <samp>CLLdU</samp> <em>is</em> legal, because the parser can determine the exact length of the data blob-- allowing it to know where the start of the next field would be. </p> |
| <h1 id="rfc.section.3.4"><a href="#rfc.section.3.4">3.4.</a> <a href="#structured-data" id="structured-data">Structured Data</a></h1> |
| <p id="rfc.section.3.4.p.1">The structure data type (<samp>t(...)</samp>) is a way of bundling together several fields into a single structure. It can be thought of as a <samp>d</samp> type except that instead of being opaque, the fields in the content are known. This is useful for things like scan results where you have substructures which are defined by different layers. </p> |
| <p id="rfc.section.3.4.p.2">For example, consider the type signature <samp>Lt(ES)t(6C)</samp>. In this hypothetical case, the first struct is defined by the MAC layer, and the second struct is defined by the PHY layer. Because of the use of structures, we know exactly what part comes from that layer. Additionally, we can add fields to each structure without introducing backward compatability problems: Data encoded as <samp>Lt(ESU)t(6C)</samp> (Notice the extra <samp>U</samp>) will decode just fine as <samp>Lt(ES)t(6C)</samp>. Additionally, if we don't care about the MAC layer and only care about the network layer, we could parse as <samp>Lt()t(6C)</samp>. </p> |
| <p id="rfc.section.3.4.p.3">Note that data encoded as <samp>Lt(ES)t(6C)</samp> will also parse as <samp>Ldd</samp>, with the structures from both layers now being opaque data blobs. </p> |
| <h1 id="rfc.section.3.5"><a href="#rfc.section.3.5">3.5.</a> <a href="#arrays" id="arrays">Arrays</a></h1> |
| <p id="rfc.section.3.5.p.1">An array is simply a concatenated set of <em>n</em> data encodings. For example, the type <samp>A(6)</samp> is simply a list of IPv6 addresses---one after the other. The type <samp>A(6E)</samp> likewise a concatenation of IPv6-address/EUI-64 pairs. </p> |
| <p id="rfc.section.3.5.p.2">If an array contains many fields, the fields will often be surrounded by a structure (<samp>t(...)</samp>). This effectively prepends each item in the array with its length. This is useful for improving parsing performance or to allow additional fields to be added in the future in a backward compatible way. If there is a high certainty that additional fields will never be added, the struct may be omitted (saving two bytes per item). </p> |

| <p id="rfc.section.5.p.1">Spinel is largely a property-based protocol, similar to representational state transfer (REST), with a property defined for every attribute that an OS needs to create, read, update or delete in the function of an IPv6 interface. The inspiration of this approach was memory-mapped hardware registers for peripherals. The goal is to avoid, as much as possible, the use of large complicated structures and/or method argument lists. The reason for avoiding these is because they have a tendency to change, especially early in development. Adding or removing a property from a structure can render the entire protocol incompatible. By using properties, you simply extend the protocol with an additional property. </p> |

| <p id="rfc.section.A.1.p.4">We also <strong>RECOMMEND</strong> an Arduino-style hardware reset, where the DTR signal is coupled to the <samp>R̅E̅S̅</samp> pin through a 0.01µF capacitor.

| <p id="rfc.section.A.1.1.p.1">When using a UART, the issue of an appropriate bit rate must be considered. A bitrate of 115200 bits per second has become a defacto standard baud rate for many serial peripherals. This rate, however, is slower than the theoretical maximum bitrate of the 802.15.4 2.4GHz PHY (250kbit). In most circumstances this mismatch is not significant because the overall bitrate will be much lower than either of these rates, but there are circumstances where a faster UART bitrate is desirable. Thus, this document proposes a simple bitrate detection scheme that can be employed by the host to detect when the attached NCP is initially running at a higher bitrate. </p> |
| <p id="rfc.section.A.1.1.p.2">The algorithm is to send successive NOOP commands to the NCP at increasing bitrates. When a valid <samp>CMD_LAST_STATUS</samp> response has been received, we have identified the correct bitrate. </p> |

This will induce the slave device to indicate the length of the frame it wants to send (if any) and indicate the largest frame it is capable of receiving at the moment. This allows the master to calculate the size of the next transaction. Alternatively, if the master has a frame to send it can just go ahead and send a frame of that length and determine if the frame was accepted by checking that the <samp>RECV_LEN</samp> from the slave frame is larger than the frame the master just tried to send. If the <samp>RECV_LEN</samp> is smaller then the frame wasn't accepted and will need to be transmitted again. </p> |

If these bits are set for both the master and slave frames, then CRC checking is enabled on both sides, effectively requiring that frame sizes be two bytes longer than would be otherwise required. The CRC is calculated using the same mechanism used for the CRC calculation in HDLC-Lite (See <a href="#hdlc-lite">Appendix A.1.2</a>). When both of the <samp>CRC</samp> bits are set, both sides must verify that the <samp>CRC</samp> is valid before accepting the frame. If not enough bytes were clocked out for the CRC to be read, then the frame must be ignored. If enough bytes were clocked out to perform a CRC check, but the CRC check fails, then the frame must be rejected and the <samp>CRC_FAIL</samp> bit on the next frame (and ONLY the next frame) MUST be set. </p> |
