There are three IQRF values needed to generate Smart Connect QR Code. Two of them (MID and IBK) are unique for every IQRF transceiver while HWPID is fixed for the specified product and is independent of the contained physical IQRF transceiver. So the task is to read out the MID and IBK from the IQRF transceiver that is part of the product.
If the SPI signals of the IQRF transceiver are accessible then the best way is to use the SPI bus for reading out the values. If the IQRF transceiver can be physically inserted into CK-USB-04A then IQRF IDE can read out the values. Either use USB Device/Show TR Module Info (Ctrl+M) or Tools/IQRF Code Tools (Ctrl+Alt+S). When IQRF transceiver cannot be inserted into CK-SUB-04A then it is often possible to connect SPI bus with CK-USB-04A by separate wiring. Another way is to read out the value by a custom device according to the IQRF SPI specification or to use IQRF_IDE_Command.exe.
If the SPI bus is not available then DPA Service Mode at IQRF IDE can be used to read out the values supposed DPA plug-in is already uploaded at the IQRF transceiver. Please follow the IQRF IDE documentation and then go to Tools/CATS Service Tools/DPA Service Mode.
