Hi,
I wanted to understand better about the SERIAL FRAMES coming via Collection and sent through Dissemination Services in TinyOS. I have understood completely about the serial frame received in CTP, the following thread by Phil really helped. http://mail.millennium.berkeley.edu/pipermail/tinyos-help/2007-July/0265 57.html I verified the complete frame in Collection using BRAY's TERMINAL as it gives the exact bytes coming out of the RS232. But I want to understand what does the serial port TRANSMITS when it sends a Dissemination packet to the network. (For DRIP implementation). For collection, the complete packet structure is: typedef nx_struct { > nx_uint8_t serialDelimiter; > nx_uint8_t serialProto; > nx_uint8_t serialDispatch; > > nx_am_addr_t dest; > nx_am_addr_t src; > nx_uint8_t length; > nx_am_group_t group; > nx_am_id_t type; > > nx_ctp_options_t options; > nx_uint8_t thl; > nx_uint16_t etx; > nx_am_addr_t origin; > nx_uint8_t originSeqNo; > nx_collection_id_t type; > > nx_am_addr_t source; > nx_uint16_t seqno; > nx_am_addr_t parent; > nx_uint16_t metric; > nx_uint16_t data; > nx_uint8_t hopcount; > nx_uint16_t sendCount; > nx_uint16_t sendSuccessCount; > > nx_uint16_t serialCrc; > nx_uint8_t serialDelimiter; > } msg_format_t; CAN SOME one please guide me about the serial frame for the message TRANSMITTED using DRIP. My understanding is that it should be something like this: nx_uint8_t serialDelimiter; nx_uint8_t serialProto; nx_uint8_t serialDispatch; nx_am_addr_t dest; nx_am_addr_t src; nx_uint8_t length; nx_am_group_t group; nx_am_id_t type; DRIP headers????? APPLICATION SPECIFIC HEADERS, say for example from Antitheft application, the following three data items: nx_uint8_t alert; nx_uint8_t detect; nx_uint16_t checkInterval; nx_uint16_t serialCrc; nx_uint8_t serialDelimiter; I am trying to set up a 25 node network and I have almost completed it. I am doing network testing NOW and will send my results soon. I am trying to develop a front end application for data aggregation using C#. Has anyone implemented anything with C# or .NET??? Another person is ready to help me to develop this front end if I can tell him the exact coming in and out of the serial port. Thanks, Varun Jain
