does knxlib.ping('1.1.0') require TP1 connection?

[kropfm]

Hello

I seem to be totally talent free when it comes to scripting. I've used the following code to check the existence of the IP/TP couplers . But get all 'falses' as a result in the log, when in fact only one of them is offline, 1.4.0. I must add that my LM is connected to the bus through IP. Does it require the TP1 bus connection? I get no errors, just false results.

Code:

result1 = knxlib.ping('1.1.0')

sleep(3)
result2 = knxlib.ping('1.2.0')

sleep(3)
result3 = knxlib.ping('1.3.0')

sleep(3)
result4 = knxlib.ping('1.4.0')

log(result1,result2,result3,result4)

the results:
* arg: 1
  * bool: false
* arg: 2
  * bool: false
* arg: 3
  * bool: false
* arg: 4
  * bool: false


Look forward to hearing from you.

Cheers!
