Hi Abe,
Thanks for the reply

Yes this will likely explain the missing packets as i was hammering it from the ide to see what was going on.

However with the debug vs stand alone code there seems to be still an issue.

True we are in a 5 second thread but under normal condition we only send on sensed events.
In the test setup I have it the unit will power up and send one message and then wait for an event.
this is what i see under debug with no breakpoints but stand alone nothing happens.

Is there a power on wait period required before trying to send?

Regards
Bart
