Sending file over mqtt using mqttClient-for-Legato

hi i am using mqttClient-for-Legato.
I am able to publish data.
But i am not able to send file using “mqtt pubfile topic filename”
It says cannot open file and I have already given all the permissions.

Any help would be appreciated


From the code, it is simply using mqttClient_PublishFileContent() and readFile() in mqttClientApi.c to read the file you specified.
Suggest you debugging by trying to open it by copying those code to another hello world project.
