JSon via MQTT escaping issue

[psyciknz]

I know I’ve got an escaping issue.

I have thw following json I want to me able to send as the on Commandtopic for mqttv2:

on="{"command":"c:\\Windows\\SysWOW64\\WindowsPowerShell\\v1.0\\powershell.exe"},

I’ve left the json as I want it to appear in teh mqtt server.
What escaping do I need to get it to supply the above.
I’ve tried replacing all the internal " with ’ and “” and " to no avail.

Can you show the full configuration? The snippet is certainly missing at least a trailing "…

My first guess would be:

on="{\"command\":\"c:\\Windows\\SysWOW64\\WindowsPowerShell\\v1.0\\powershell.exe\"}",

… though you may need to adjust all your double \\ to quadruple \\\\…

It’s for running a powershell command via IOTLink on windows.
