JSON is built on two structures:

• A collection of name/value pairs. In various languages, this is realized as an object, record, struct,

dictionary, hash table, keyed list, or associative array.

• An ordered list of values. In most languages, this is realized as an array, vector, list, or sequence.

An example data JSON packet as sent by the ORB is shown below:

Figure 8.1. Example JSON data packet

Users of the Senquip Portal do not need to understand the data format; data can be viewed on the
Senquip Portal numerically or graphically or can be downloaded in spreadsheet format.

If required, further details of the ORB data and setup message format are available from Senquip.

8.3 Data Buﬀer

Where  neither  Wi-Fi  or  GSM  networks  can  be  found,  the  ORB  can  store  up  to  1MByte  of  messages  to
internal memory for later transmission when a network becomes available.  When the internal memory is
full, the ORB will erase the oldest messages.  Once network connectivity is established, the most recently
