Schematics and PCB notes

Notes on the SIM868 Module

• it needs it's 2A peak current recommend connecting power to a battery
• APN doens't really matter what you call it (at least Etisalat egypt)

Notes about data_server

• there is a 30char hard limit on token names
• Expected Hz is .5Hz
  • i.e 30 logs is a minute of data

• About tokens

  • We have 2 kinds of tokens

    • Client Tokens

      • Set by "login" on the client
      • Used for Push notifications and everything else client related by car_token agnostic

    • Car Tokens

      • Preset in QR code on the Device it self
      • Multiple Client tokens can be registered to the Same Car Token
  • ALL Tokens are expected to look like ```xxxx-xxx-xxxx`` this is very critical for Car Tokens since the client expects this to be the case before sending them to the Server

Config Vars

data_server/tests/test_api.py

• email is the email to register the token with
• CAR_DATA_KEYS is the JSON keys expected as the output of the API for for the getData
• TOKEN_METADATA_KEYS is the JSON keys expected outputs of the API for get_metadata
• NOTF_KEYS is the JSON keys expected output of the API for get_notfs
• real_hz how often (in hertz) do we send the data to the server?
• min_of_speeding_to_alert how many minutes should pass before warning the user to a speed_exceeding event?
  • see #17

    server_uri="http://localhost:7060"
    email="mohamed.emad4bubble@gmail.com"
    CAR_DATA_KEYS=["car_token","lat","lot","speed","accuracy","Unixtimestamp"]
    TOKEN_METADATA_KEYS=["car_token","client_token","max_spd"]
    NOTF_KEYS=["client_token","title","msg"]
    real_hz=.5

data_server/notf_man.py

How many logs should pass before sending a warning notf?

    self.MAX_THROT_ENTRIES=15 # 30 logs means a min of speeding
