I am attempting to port the example program STAR_NOBEACON from the MAC_v_2_7_0 esamples using the atmega1281 as my jumping off point. I have modified the pal_board.c, pal_irq.c, and pal_config.h files as instructed in the AVR2025 notes (for my hardware) and modified the makefile to build to the atmega328.
I can walk through the code and see that everything is working OK through the wpan_mlme_scan_req(MLME_SCAN_TYPE_ACTIVE,
SCAN_ALL_CHANNELS,
SCAN_DURATION,
DEFAULT_CHANNEL_PAGE);
statement. However, after that the callbacks for
network_scan_indication_cb and usr_mlme_scan_conf(uint8_t status,
uint8_t ScanType,
uint8_t ChannelPage,
uint32_t UnscannedChannels,
uint8_t ResultListSize,
void *ResultList)
are never reached. Since my target device is only 32K and the release code is about 22K I can't seem to use full debugging mode. Thus, debug is tedious. Does anyone have any thoughts on what to test? It seems that my SPI connections are good and the RST line is good. TST pin is grounded. I get a nice MCLK signal and I assume the I/O between the at86rf230 and atmega328 is working.
I have built a similar project using the RZ600-at86rf230 setup with no issues. But I know this is a large jump to new board hardware and mcu. Any thoughts would be appreciated. TIA -Bruce |

I come up with 2 ideas how to debug this;
a) Can you check if you somehow run out of RAM ?
b) Do see interrupts on the RF230 interrupt pin at all? |

Hi Bruce,
Since you have configured as active scan,do u able to c any beacon requests over the air? |

Thanks. I will check the RAM. I will need to borrow a 'scope to check the interrupt line. I'll post later the outcome. |

Thanks. If I set up one of my Dev boards in Promiscuous mode will that serve as a "sniffer" ? My wireless experience is limited, so forgive my ignorance. |

Yes Promiscuous mode example application will give you the basic sniffer utility. It is more than enough for at early stages of testing the user application  |

Thanks firebee and uracolix for your help. I was able to resolve my problem.
It turned out that I had not set up my timer source correctly. The example code switches between two sources depending on whether the TRX is active or asleep. My active source was not valid, so when it was used all timekeeping stopped. Also, I see that the at86rf230 doesn't connect to the WPAN when in debug mode, but does so when running stand-alone. So I have been able to move on. |
