I just new bought two diffrent type xbee modules. These are XBP9B-DMUTB002 and XBP9B-DMSTB002. When I connect the xbee to my computer while using xbee adaptor , xctu couldn’t find the xbee modules. Of course, xctu recognised the COM but when started to search ,couldnt have found the module. These are the hardware configuration and software configurations, [https://resmim.net/album/ss.ZN0VH](https://resmim.net/album/ss.ZN0VH) —\> xbee and xbee adaptor photos ![image](https://us1.discourse-cdn.com/flex016/uploads/digi/original/2X/7/717fb1000ae9701ec6814f38702ba6895f8e5ded.png) ---

These are programmable modules. That is to say, they add a secondary processor between the modules pins and its RF processor that XCTU accesses. You may need to upload a sample application to this processor before XCTU will be able to talk to it. You should also enable the Programmable version option in XCTU. > **[XBee®-PRO 900HP and XSC RF Modules User Guide](https://docs.digi.com/resources/documentation/digidocs/90002173/#concepts/c_module_operation_for_programmable_variant.htm?TocPath=Hardware%257CDesign%2520notes%257C _____ 2)** ---

Thanks for your reply , Actually i have found my xbee’s and configured them with xctu ,but i can not use them with python code with digixbee library. Then i “got couldnt determine operating mode” error. Then I have searched on internet , i need to bypass the nxp microproccessor. how can i apply that ? ---

This code is not intended to be used with the Programmable versions of the XBee modules. It is intended to be used with the standard XBee modules in API Mode. For the programmable modules, you would need to port over the transparent application found in the Programmable SDK via a BDM programmer/debugger. ---

Thanks for your concern, I have solved my problem I first downloaded CodeWarrior and the XBee SDK, along with an older version of XCTU. Using the XModem interface available in the older XCTU version, I uploaded the bypass code from the XBee SDK. This allowed me to bypass the programmable XBee’s internal processor and successfully detect the XBee module in XCTU. By the way, I found and downloaded both CodeWarrior and the Programmable XBee SDK from the following document: [https://docs.digi.com/resources/documentation/digidocs/pdfs/90000976.pdf](https://docs.digi.com/resources/documentation/digidocs/pdfs/90000976.pdf), since the other download links were no longer working. ---

Hi there, I’ve had the same problem and I solved it as the same way you did. However, when I try to use my programmable modules with arduino, I cannot receive data (I serially bypassed the microchip so I think as for now my modules are same with non-programmable ones) . Have you been able to communicate between your programmable modules? If so, could you explain how you did it? ---

The Arduino requires that the radio be in API mode.
