Simple Weather Service

Introduction

The Simple Weather Service provides a simple and straightforward API to specify the current weather and the forecast for the next 5 days. It effectively replaces the original Weather Service (from InfiniTime 1.8) since InfiniTime 1.14.

Service

The service UUID is 00050000-78fc-48fe-8e23-433b3a1942d0.

Characteristics

Weather data (UUID 00050001-78fc-48fe-8e23-433b3a1942d0)

The host uses this characteristic to update the current weather information and the forecast for the next 5 days.

This characteristics accepts a byte array with the following 2-Bytes header:

  • [0] Message Type :
    • 0 : Current weather
    • 1 : Forecast
  • [1] Message Version : Version 0 is currently supported. Other versions might be added in future releases

Current Weather

The byte array must contain the following data:

  • [0] : Message type = 0
  • [1] : Message version = 0
  • [2][3][4][5][6][7][8][9] : Timestamp (64 bits UNIX timestamp, number of seconds elapsed since 1 JAN 1970) in local time (the same timezone as the one used to set the time)
  • [10, 11] : Current temperature (°C * 100)
  • [12, 13] : Minimum temperature (°C * 100)
  • [14, 15] : Maximum temperature (°C * 100)
  • [16]..[47] : location (string, unused characters should be set to 0)
  • [48] : icon ID
    • 0 = Sun, clear sky
    • 1 = Few clouds
    • 2 = Clouds
    • 3 = Heavy clouds
    • 4 = Clouds & rain
    • 5 = Rain
    • 6 = Thunderstorm
    • 7 = Snow
    • 8 = Mist, smog

Forecast

The byte array must contain the following data:

  • [0] : Message type = 1
  • [1] : Message version = 0
  • [2][3][4][5][6][7][8][9] : Timestamp (64 bits UNIX timestamp, number of seconds elapsed since 1 JAN 1970) in local time (the same timezone as the one used to set the time)
  • [10] Number of days (Max 5, fields for unused days should be set to 0)
  • [11,12] Day 0 Minimum temperature (°C * 100)
  • [13,14] Day 0 Maximum temperature (°C * 100)
  • [15] Day 0 Icon ID
  • [16,17] Day 1 Minimum temperature (°C * 100)
  • [18,19] Day 1 Maximum temperature (°C * 100)
  • [20] Day 1 Icon ID
  • [21,22] Day 2 Minimum temperature (°C * 100)
  • [23,24] Day 2 Maximum temperature (°C * 100)
  • [25] Day 2 Icon ID
  • [26,27] Day 3 Minimum temperature (°C * 100)
  • [28,29] Day 3 Maximum temperature (°C * 100)
  • [30] Day 3 Icon ID
  • [31,32] Day 4 Minimum temperature (°C * 100)
  • [33,34] Day 4 Maximum temperature (°C * 100)
  • [35] Day 4 Icon ID
