CC2480 AF_DATA_REQUEST

Does anyone know the possible options for the Transmit options field?  The documentation only says "Options – 1 byte – Transmit options"

Also, does anyone know what values can be manipulated within NV memory?

I am working on a new distance technique and need this information if anyone has it.

Thanks,
Dave

    The options are AF_ACK_REQUEST, AF_EN_SECURITY and AF_SKIP_ROUTING bit fields defined in eZ430-RF2480\common\zaccel\cc2480.h.

    You are correct, these are not documented in the CC2480 Interface Specification, as they should be.

    Hi Brandon,

    Thank you for your response. I feel like there should be at least 8 different transmit options because of the way those three, as well as AF_FRAGMENTED, AF_DISCV_ROUTE, are defined.  Specifically, I am looking for a way to turn off acknowledgments and speed up the transmission process. The three bits that are undefined are 0x02, 0x04 and 0x08.

     

    Thanks,
    Dave

    Does anyone know what these values represent? Or what NV memory values can be changed?

    The values of 0x02, 0x04 and 0x08 are in fact not defined in the CC2480.

    Are you asking about User defined non-volatile values as represented by the SYS_OSAL_NV_WRITE and SYS_OSAL_NV_READ commands?
    Or the ZCD_NV_* values?

    I am asking about user-defined values. What can be done with them?

    Is there any way to shut off acknowledgements to speed up the communication process?

    Thanks,
    Dave

    Only use AF_ACK_REQUEST to request APS ACK service for the message transmission. AF_DISC_ROUTE should always be turned on. This instructions the routing logic
    to always do a route discovery if a routing table entry for that destination does not exist.

    AF_EN_SECURITY, AF_SKIP_ROUTING are not officially supported.

    I happened to program the cc2480 ZCD_NV_STARTUP_OPTION with a value of 0x04 and now the chip behaves like crazy. It only returns the first poll for reset and accepts 1 more command after that and then just stops working.

    I have my own hardware and I am not using the demo boards. Without the previous command, my designed boards work fine but since I executed this command, its all in a mess. I have ruined 4 boards already and have none left for any more research.

    Any help will be greatly appreciated.
