DPA v4.03 for OS 4.03D - Current for TR-7xD

PDF IQRF Quickstart guide – How to start
PDF IQMESH Network Deployment Technical guide - How to implement IQRF network
PDF DPA plug-ins – Download DPA plug-ins, as a part of IQRF Startup package
INFO Custom DPA handler headers and examples - Maybe more up-to-date than the ones in Startup package


DPA v4.02 for OS 4.03D - Obsolete. A bug presents.

Errata: Any of MemoryRead+1 FRC commands also executed a DPA Request stored internally at bufferAUX (e.g. from the previous FRC AcknowledgeBroadcast). This may cause a problem expecially in Autonetwork.
Workaround: Use DPA v4.03.



DPA v4.01 for OS 4.03D - Not recommended for new designs



DPA v4.00 for OS 4.03D - Not recommended for new designs



DPA v3.03 for OS 4.03D - Not recommended for new designs

Errata: Send and Send Selective commands of the FRC peripheral pass only 20 bytes of the UserData parameter. This bug was introduced into DPA v3.03. If it is bugging you, contact IQRF support for the workaround, please. We apologize for your inconvenience.



DPA v3.02 for OS 4.02D - Not recommended for new designs

Known issues:

  • SPI Peripheral: The DPA for Node without DPA interface support at standard RF mode (HWP-Node-STD-7xD-V302-171116.iqrf or HWP-Node-STD-7xD-V301-170814.iqrf) does not initialize enabled SPI Peripheral.
    Workaround: Call enableSPI() at DpaEvent_Init event.
  • UART interface shutdown: The DPA for Coordinator with a UART interface (HWP-Coordinator-STD-UART-7xD-V302-171116.iqrf or HWP-Coordinator-LP-UART-7xD-V302-171116.iqrf) does not shutdown the UART interface before Discovery, Reset, Restart, Run RFPGM and LoadCode commands are executed. This might cause a malfunctioning in case of Discovery or missing DPA Response in other cases.
    Workaround: Enable Node interface at the HWP Configuration although the device is the Coordinator.
These issues are fixed in DPA v3.03. Thus, the best workaround is to migrate to OS v4.03D and DPA v3.03.
