What's happening?

  • Followup: RE: I can read from bus but I cannot write to it

    Sorry, but it's not possible to reproduce/diagnose the problem based on this description. You may also want to try Calimero NG- it has quite some improvements over 1.x! Regards, Georg.

  • Followup: RE: ESF reference file with list of all DPTs

    Hello, You mean the "EIB session file" that is created via "File" > "Extract Data (e.g. OPC)..." > "Export to OPC Server" in ETS3, whose 3rd column says things like "Uncertain (2 Byte)", right? If so, this is a tool-specific issue and definitely not covered by the KNX specification. Maybe support@knx.org can help? Georg.

  • Followup: RE: message between client and server

    Matteo, You're welcome. The PropClient tool is intended as an example to display the capabilities and usage of the Calimero library, not as a reference implementation of the KNX standard. That is why there are more service invocations than strictly necessary: The property value is not printed after the first PropertyValue\_Response is received, but only after an additional...

    > There are time limits for responses > from shrinking? Sorry, I do not understand. > Once you receive the message TUNNELLINGREQUEST (CEMI LData.ind: APropertyValueResponse-PDU), the client should print on screen the result of the request, right? The PropClient tool actually sends two *A_PropertyValue_Read* requests, plus a *A_PropertyDescription_Read* inbetween. Apparently...

  • Followup: RE: message between client and server

    Assuming a connectionless(!) *A_PropertyValue_Read*, the remaining messages are (leaving the Tunnelling connection open): Server sends TUNNELLING_ACK Server sends TUNNELLING_REQUEST (cEMI L_Data.con: A_PropertyValue_Read-PDU) Client sends TUNNELLING_ACK Server sends TUNNELLING_REQUEST (cEMI L_Data.ind: A_PropertyValue_Response-PDU) Client sends TUNNELLING_ACK HTH...

  • Followup: RE: Dimming with CalimeroNG

    Probably, you want to use a "step code" of 1 (i.e., "increase 1")- that's what most (if not all) push buttons send. The "step code" denotes the fraction (!) of the dimming range the actuator should sweep (until stopped by a "break"). Also, this would be a CommandDP (not a StateDP, since there is no state you could possibly read back from this group...

  • Followup: RE: NAT/Internet routing

    This is mainly a firewall/switch setup issue- depending on how your network is configured (and the security requirements you have!), a VPN may be useful/necessary. KNXnet/IP Tunnelling uses IP unicast (UDP in all cases known to me), the default port number is 3671; originally, it did not support NAT natively (and many devices still do not), since the IP address is/was included in the...

  • Followup: RE: How to watch / read group status

    Houssem, On KNX/EIB, datapoint values are "pushed" via GroupValue_Write or can be "pulled" via GroupValue_Read, depending on the configuration of the devices in the network. In Calimero, the ProcessCommunicator provides the easiest access to these services. The ProcComm "tool" actually is a code example for this API. HTH, Georg.
