Parse data from a new controller

alari76 commented 10 years ago

The new controller has a following data format:

<11;336;838;343;33><11;336;838;343;34><13;28;164>

<SensorID; Temperature; Battery voltage; Humidity; Sendcounter>

Each package can consist of several sensor messages, and it always ends with a controller message (3 items) -

<ControllerID; GSM coverage; Battery voltage>

Temperature is calculated using a specific table. Will be updated later
Battery voltage for sensor - multiply the number with * 0.00384 to get exact voltage
Humidity - store this number without modifications
Sencounter is used to deduct the time of the reading. Each count equals to 30 minutes.
GSM coverage - store this number without modifications. Scale is 0-31, where bigger number is better.
Battery voltage for controller - it will have a different coefficient from the sensor. Initially just store this number without modifications.
There might be a bug in the controller, where it sends garbage data after the closing '>'. Just ignore data that is located between '>' and '<'.

Garbaged data can be something like this -

<11;335;838;343;200;59>><10;344;873;211;175>40>><10;344;871;211;177>41>><10;344;873;211;179>42>>~<13;23;200>

Please note that new protocol does not include timestamps, so we have to use server's clock to timestamp data.

Can you give me a couple of example packages? For test cases
