Hi,
we are using DW1001 module for ranging (initiator and responder). I got the code from git https://github.com/Decawave/dwm1001-examples. This example is for only two device ranging and MAC filter added in the Nordic controller code. It is working perfectly for me.
Now we are trying to range with multiple responders from multiple initiators. Using the above code it is not possible because of MAC filtering is in the Nordic code. So I used to enable frame filtering on it. But device is not ranging when enabled frame filtering (not receiving any packets in the responder code)
Here is the code for initializing,
static dwt_config_t config = {
5, /* Channel number. /
DWT_PRF_16M, / Pulse repetition frequency. /
DWT_PLEN_1024, / Preamble length. Used in TX only. /
DWT_PAC32, / Preamble acquisition chunk size. Used in RX only. /
3, / TX preamble code. Used in TX only. /
3, / RX preamble code. Used in RX only. /
1, / 0 to use standard SFD, 1 to use non-standard SFD. /
DWT_BR_850K, / Data rate. /
DWT_PHRMODE_STD, / PHY header mode. /
(1025 + 64 - 32) / SFD timeout (preamble length + 1 + SFD length - PAC size). Used in RX only. */
};

Please correct mem if am doing anything wrong. Help me out to figure this issue.
