HTTP over Serial


Serial interface Paramaters

  • 115200 8N1
    • 115200 Baud
    • 8bits
    • no parity
    • one stop bit


Packet format:

  • [STX][message-string][ETX][CRX]
    • [STX] start of text, (0x02)
    • [message string] (CGI in, JSON out)
    • [ETX] end of text (0x03)
    • CRC: 2 bytes xmodem CRC


Example 1:

 request -> [STX] statusjsn.js?components=16384&svt=1&svi=1&svf=1&brief=1 [ETX] [CRC:0x5d49]
 answer  <- [STX] { "sensor_values":[[[1,1,null,1],[[237.310]]]],"eof":1 } [ETX] [CRC:0x5d49]


Example 2:

 ./hosd --port /dev/ttyS0 --cgi "statusjsn.js?components=16384&svt=1&svi=1&svf=1&brief=1" --batch | python -m json.tool
