Can you post complete script listing?

Hi, yes here it is;
Thank you

Code:

mqtt = require("mosquitto")
client = mqtt.new()
client:tls_set('/data/ftp/ca.pem', nil, '/data/ftp/client.pem', '/data/ftp/client.key')

client:tls_insecure_set(true)

client.ON_CONNECT = function()
log('connected')
value = grp.getvalue('0/3/4') or 0
client:publish("SOME/TOPIC/1", value, qos, retain)
value = grp.getvalue('0/3/5') or 0
client:publish("SOME/TOPIC/2", value, qos, retain)

client:login_set('someuser', 'somepass')
client:connect(broker,8883)
