I tried changing to sandboxed: false in my application.adef before but it didn’t help.
The application I’m writing is using the mqttClientService (and mqttClient). Looking at the .adef definition file here https://github.com/legatoproject/legato-af/blob/master/apps/platformServices/mqttClient/mqttClient.adef the sandboxed is set to true.
I changed the mqttClient.adef files sandboxed to false and now it works. I can also use a DNS name instead of IP address.
Should the mqttClient.adef sandboxed property be set to true, or should all platformServices be set to false by default?
