CC2530+CC2591 Problem

Other Parts Discussed in Thread: CC2591, CC2530, CC2530EM

Hi,

I have used CC2530+CC2591 in one of our design and followed the reference design from TI(CC2530_CC2591_EM_Schematic.pdf). After I performing the verification test using SmartRF Studio 7 and Packet Sniffer, we found that the performance is very bad compared with other board which is not used CC2591.

My questions are,

1. How do I know the chip of CC2591 is working or not?

2. Have any simple way to check the chip of CC2591 from my side?

Thanks in advance.

Regards,

Porter Liu

    Dear Porter Liu

     

    The simplest method to check CC2530-CC2591 combined performance is naturally a Spectrum analyzer. Since you posted this question I assume you don’t have access to an instrument like that.

    If you have another 2.4GHz radio (It can be another CC2530EM) you can monitor RSSI while changing transmission power in your CC2530+CC2591 Design.  
    Monitoring current while changing between RX, RX+HGM and TX at different power settings should give some indication of operation. Values close to expected (calculated from datasheets) are a good sign. Large deviations in current consumption probably indicate some kind of trouble.
    These are the most basic test I can think of without more specialized lab equipment.

     

    However any new design should be fine tuned and characterized using proper test equipment.

    You can check http://focus.ti.com/general/docs/gencontent.tsp?contentId=29028 for providers of such test/engineering capacities in your area. You’re qualification partner for regulatory verification (ETSI, ARIB, FCC…) might also provide help with these initial test/characterization tasks prior to the final qualification measurements and compliance application.

    Hi Porter Liu,

    You can also buy the RC24xxHP module from Radiocrafts that is already tested to high preformance, tested over temperature and different antenna loads, fully characterised and CE/FCC tested.

    If you are not experienced in RF design this could same a lot time and effort for you. The module consist of CC2591 + CC2530. We also have options with integrated antenna.

    Let me know if you would like more information.

    If you're using the TI-Zstack then you also need to be sure to build it with the proper compilation flags for CC2591. The software needs to configure some of the IO pins as RF control pins which is not done unless you build the stack with the compilation flags.
