USB communication protocol specification

USB ACM serial port is used when communication is through USB.

Data format

Both USB connection and cloud connections will use CBOR for Things Messages. CBOR has the exactly same content as JSON, but it is compressed to optimise data-size. Things Message specification contains JSON-CBOR mapping table and reference conversion functions between these two formats.

CBOR messages send from device to cloud are compressed using zlib library compiled with parameters suited for embedded SW use. CBOR message send to device from cloud are not compressed (as ready built zlib libraries are compiled with parameters that are not suited for embedded use, that is too large memory usage).

USB serial message protocol

USB Events (HUB->PC) format

Event line format:

(E,<timestamp>,<event-type>,<event-payload>,<crc-checksum>)
  • <timestamp>: Unix timestamp of event (device time, UTC timezone), for example: 1504614160.510
  • <event-type>: type of event, for example: TSM
  • <event-payload>: base64 encoded event payload, for example: OWuV0+z7Cpc=
  • <crc-checksum>: See section ‘CRC Checksum’.

USB Event types

  • “TSM”: payload is CBOR message as described in Things Message specification.
    • Example:

USB Commands (PC->HUB) and responses (HUB->PC) format

Command line format:

(C,<command-id>,<command>,<command-payload>,<crc-checksum>)

Command response line format:

(R,<command-id>,<return-code>,<response-payload>,<crc-checksum>)
  • <command-id>: unique identifier for command/request pair.
  • <command>: type of command, for example: CONFIG_GET
  • <command-payload>: base64 encoded command payload
  • <return-code>: 0 or above if successful, negative number if command failed.
    • Common error codes: -1000=unknown command
  • <response-payload>: base64 encoded response payload
  • <crc-checksum>: See section ‘CRC Checksum’.

USB Commands

  • GET_VERSION: Ask SW version from gateway. Response payload is a string containing SW version number.
  • GET_TUID: Ask TUID from gateway. Response payload is a string containing Thing Unique ID for gateway.
  • CONFIG_GET: Get configuration parameter. Command payload is a string “<key>”, and response payload is “<key>=<value>”, where
    • `: key for configuration item,
    • <value>: value for configuration item.
    • Return code ‘-1’ returned if given <key> does not exist.
    • Example:
  • CONFIG_SET: Set configuration parameter. Command payload is a string “<key>=<value>”, where
    • <key>: key for configuration item,
    • <value>: new value for configuration item.
    • Example:
  • SEND_TSM: Send Things Message CBOR to gateway. Command payload is a Things Message CBOR message.
  • GET_TIME: Ask SW version from gateway. Response payload is a string containing current Unix time in UTC timezone, for example, “1504615898.570687”.
  • SET_TIME: Set system time for gateway device. Command payload is a string containing current Unix time in UTC timezone, for example, “1504615898.570687”.
  • REBOOT: Reboot gateway device.
  • DFU_MODE: Reset gateway device to DFU mode.

CRC Checksum

Message checksum algorithm is CRC-24 with initializer 0xB704CE and generator 0x864CFB. For reference implementation, see RFC 2440 section ‘6.1. An Implementation of the CRC-24 in “C”’. The checksum is calculated starting from initial ‘(’ character to last ‘,’ character of the message. The calculated CRC-24 checksum is base64 encoded and included after last ‘,’ character of the message.

  • Example message with correct CRC-24:
    (E,1504614160.510,TEST,OWuV0+z7Cpc=,T40+)
    
  • CRC-24 calculated for “(E,1504614160.510,TEST,OWuV0+z7Cpc=,” is 0x4F8D3E and this CRC-24 value encoded as base64 is “T40+”.
