[OLD] LogicMachine firmware 2018.08

[AEK]

* arg: 1
 * bool: false
* arg: 2
 * nil

as I said before the upgrade script was working

Are you sure device is present?

just checked on my lm3 with rs232 port firmware 20180828

res, err = knxlib.ping('1.1.3')

log(res, err)
if device exist
* arg: 1
 * bool: true
* arg: 2
 * nil
else
* arg: 1
 * bool: false
* arg: 2
 * nil

what do you see in ETS group monitor ?
