CC2430: Customized ZigBee customized radio settings not able to receive in other SoC

Michal Piekut

Part Number: CC2430

We use CC2430 for customized product. The only radio change we did comparing to standard ZigBee is as below:

SYNCWORDL = 0x0B;

SYNCWORDH = 0xE4;

//[  preamble][sync  ]

//[00][00][00][0B][E4]

 

I have an issue configurating Silicon Labs chip to receive your packet. We tried a lot of things without succes.

On things which came into our mind was what are the settings for DSSS in CC2430. Here is screenshot what I can set in SL chip:

SL support didn't succeed yet, hence they tried decode RF raw data and had beginning 0x00 0x00 0x00 0x0A matched symbols (with DSSS Chipping Code Base as in the picture)

, but the rest doesn't match patterns.

Can anyone help with this issue?

Thanks!

    Hi,

    From your description it seems that your product is already in production, is that so? If that is true and it works with other devices, then the issue is localized in the SiLabs device and we can't help.

    If that is not the case, then I would check the CC2430 output with a packet sniffer to see if the Zigbee packets are being sent successfully over the air. I would retry with the default sync words and see if the issue can be overcome. From the snippet of code you showed, there is nothing seemingly wrong with the sync words chosen.

    Unfortunately the CC2430 device is not recommended for new designs and we don't support the Silicon Labs device, thus our support actions are limited in this case.

    Hope this helps,

    Rafael

    Hi Rafael,

    Product is in production for around 15 years and we need to find another compatible hardware. Unfortunatelly it is quite difficult due to protocol changes (yes, we might regret it now, but it is too late). SL seems to be perfect and even SL support has issues making it receiving.

    They have our hardware and did RF raw bits. There is still something wrong with it. I can share it with you where you might be able decode it to actual packet bytes. If we know what CC2430 is sending, we know how to configure radio in SL.

    Thanks,
