ADF7023 cann't received packet

HI,

I am used ADF7023 chip.

But   I can't received the packet.I used packet mode.We used a module to  send packets by RF, and I test the anthor module's gp3 by oscilloscope, it is always logic high.

I used the spectrum,I can see the module can send CW wave.

The config:

struct ADF7023_BBRAM ADF7023_BBRAMDefault =

Anther qustion:

We used 1K bate,then send one byte by RF ,It may need 287ms,is it correct?

Best regards,

Kanta

  • Hi Kanta,

    You have to clear an interrupt after it is generated.

    With your configuration, the packet would comprise of 32 bytes preamble, 8 bytes sync word, 2 bytes CRC, 2 bytes Postamble, and 4 bytes payload (1 byte length, 2 bytes address, 1 byte data).

    The time to transmit/receive the packet would be around:

    ((32 + 8 + 2 + 2 + 4) * 8 bits/bytes)  / 1000 bps = 384 ms

    Regards,

    Aldrich
