I would likes to use a 12 alphanumeric characters in CAPS for the device id of the edge. I have also configured the TSI. Is there any character limitations for JSON input fields from edge device.?

Sample JSON would be something like as follows.



"key1" : "value1",

"key2" : "value2",

"key3" : "value3",

"key4" : "value4" etc..


Is there any thing should be concerned for the 12 alphanumeric characters in CAPS for the DeviceID.?

DeviceId: A case-sensitive string (up to 128 characters long) of ASCII 7-bit alphanumeric characters plus certain special characters: - . + % _ # * ? ! ( ) , = @ $ '.
