Hi Phil, thanks for the reply.
I have received the JSON data using a test application and it looks like this:
POST / HTTP/1.1
Host: 192.168.1.113:1883
Accept: /
Content-Length: 64
Content-Type: application/x-www-form-urlencoded
[{"ID":"2", "TS":"1566412285","ST":"71","VR":"[66,71,183,224]"}]POST / HTTP/1.1
Host: 192.168.1.113:1883
Accept: /
Content-Length: 63
Content-Type: application/x-www-form-urlencoded
[{"ID":"2", "TS":"1566412286","ST":"1","VR":"[67,110,14,168]"}]
The data i want are the 2 numerical values - 66,71,183,224 and 67,110,14,168 - Frequency and Voltage values.
It also took me a while to figure out the data format. Its a 32Bit float but each 8 bits is in decimal. I have gotten the correct values by converting each 8 bits to binary and inputting the result into a IEE754 converter. Can this be done with the data in mango?
As i said I have the device sending the data to the test app, running on the same pc as mango, but when i change the url to 192.168.1.113/httpds and use the listen function on the data source setup menu I don't get anything back.
Thanks again Phil.
