Hi, Here I use JSON utility library to code and decode the JSON data string. Now JSON_Coder works fine to create JSON data in root object. Example below: { \t"application": „external“, \t"requestId": „b84“ } But the manual is not very clear about how to create the next leve JSON Data, example below. The JSON in data section. { \t"application": „external“, \t"requestId": „b840e6f4-5502-4fde-aa15-3c396f4422ce“, \t"responseTo": „csp/response/EV002“, \t"type": „device write“, \t"data": { \t\t"data1":„v1“, \t\t"data2":„v2“ \t} } Did someone have any experience on this? Thank you. Xinjun
Hello Xinjun, I am afraid that what you want to do is not possible with the current version of the JSON coder. The manual states: [quote]The multiple instances of this method allow to build a full tree of JSON elements, with the exception of the JSON arrays and JSON objects.[/quote]In this case „JSON objects“ means the „next level JSON data“ that you refer to. This feature might be included in a future version of the JSON coder. ~ Martin.
