(Mono C#) JSON Estimote DataDemonstrates accessing some data from an Estimote REST API response. The Estimate REST API responds with a JSON array (i.e. something beginning with "[" and ending with "]"). To parse, this must be made into a JSON object by prepending "{"*":" and appending "}". This example uses the following JSON object: {"*":[{ "id" : "B9407F30-F5F8-466E-AFF9-25556B57FE6D:28203:50324", "uuid" : "B9407F30-F5F8-466E-AFF9-25556B57FE6D", "major" : 28203, "minor" : 50324, "mac" : "dd6fc4946e2b", "settings" : { "battery" : 100, "interval" : 950, "hardware" : "D3.4", "firmware" : "A3.2.0", "basic_power_mode" : true, "smart_power_mode" : true, "timezone" : "America/Los_Angeles", "security" : false, "motion_detection" : true, "latitude": 37.7979, "longitude": -122.4408, "conditional_broadcasting" : "flip to stop", "broadcasting_scheme" : "estimote", "range" : -12, "power" : -12, "firmware_deprecated" : false, "firmware_newest" : true, "location" : null }, "color" : "blueberry", "context_id" : 339488, "name" : "blueberry ibeacon1", "battery_life_expectancy_in_days" : 1377, "tags" : [] }, { "id" : "B9407F30-F5F8-466E-AFF9-25556B57FE6D:25845:21739", "uuid" : "B9407F30-F5F8-466E-AFF9-25556B57FE6D", "major" : 25845, "minor" : 21739, "mac" : "ff5454eb64f5", "settings" : { "battery" : 100, "interval" : 950, "hardware" : "D3.4", "firmware" : "A3.2.0", "basic_power_mode" : false, "smart_power_mode" : true, "timezone" : "America/Los_Angeles", "security" : false, "motion_detection" : true, "conditional_broadcasting" : "flip to stop", "broadcasting_scheme" : "estimote", "range" : -12, "power" : -12, "firmware_deprecated" : false, "firmware_newest" : true, "location" : null }, "color" : "blueberry", "context_id" : 339483, "name" : "blueberry2", "battery_life_expectancy_in_days" : 1168, "tags" : [] } ]}
