Other Parts Discussed in Thread: MSP430F5438, TIMAC, CC2531EMK

hai i am using the cc2520-2591 emk when i configure the chip and  simply load the data  in the txfifo buffer  in one board and transmit the data.on the other side  by disabling the frame filter enable bit FRMFILT0.FRM_FILTER_EN and i start receiving the data on the other board i get the same data what i was transmitting is received  on the rxfifo buffer .

 

i want to know  the IEEE802.15.4 frame format details
and the local address information that is SHORT_ADDR ,PAN_ID,EXT_ADDR

and Source address matching control.

    Did you look at http://www.ti.com/tool/timac? TIMAC is TI's implementation of the 802.15.4 MAC. It contains multiple projects for implementing a IEEE802.15.4 MAC, the EXP5438 project using the CC2520-CC2592 EMK. All the code you need is already written for MSP430F5438, you can use the MSP430F5438 (www.ti.com/.../msp430f5438) and take the code as is, or you can use it as a reference.

    Alternatively you could consult the spec standards.ieee.org/.../802.15.html

    regards,
    TC.

    hai thanks for the information that you have shared with me. i put my transmitter board into ieee 802.15.4 frame format and i transmited when i captured the data using the cc2531emk dongle the frame is fine when i receive in my receiver board by enableing the frame filter and reading the rxfifo the length byte and mac payload and source address are all corrupt but the FCF and sequence no and destpanid and destaddress are receiveing correct is it my frame filtering algorithm and address mathing enable table problem and i receiving the rejected frame.
