Hi, I thought I did, but well, here it is again.I am trying it with a tag 3M Hi Strength (ISO 15693), which with my other PCMCIA reader I receive 0xE0070000121F24CC, but instead, with Listen, I get:
FF FF 51 17 10 01 0A 00 00 C2 02 32 34 30 30 30 30 30 30 30 30 FF FF 51 17 10 01 0A 00 00 0E 03 32 34 30 30 30 30 30 30 30 30 FF FF 51 17 10 01 0A 00 00 D5 02 32 34 30 30 30 30 30 30 30 30 FF FF 51 17 10 01 0A 00 00 D1 02 32 34 30 30 30 30 30 30 30 30 FF FF 51 17 10 01 0A 00 00 1E 03 32 34 30 30 30 30 30 30 30 30Can you give me any hints on this 'conversion'? I tried to interpret the bit pattern and I only got to what is in the pdf. Thanks for your help!

Hello Pablo, Did you send be a PDf attachment? I didnt receive it so not sure what your analysis is. The output from Listen is raw bytes and you need to convert them to appropriate integers of character values before you can work with it. The message interface file does that conversion for you making it easy to understand the output. Shweta On Thu, 2 Feb 2006, Pablo Guerrero wrote:Hello Shweta, thanks for the hints. I am currently inspecting the code you sent, I appreciate it. In the meantime I sent you a pdf with my analysis of what I was receiving with the Listen tool. Because still that is what I receive, right? To make my scenario clearer: First Mote: Mica2 with Skyetek M1Mini RFID reader attached (through a basic sensor board MTS101CA). Running 'TestSkyeReadMini2_Poll'. Should read tags' info and put it in the radio. Second Mote: Mica2 attached to the programming board, running 'TOSBase'. Should forward what receives through UART and put it in the radio and viceversa. PC: Running the java 'SerialForwarder' and 'Listen' programs. What software are you using in the first mote? I also have an xRFID but could not use it since some libs are missing :( Thanks Pablo Shweta Jain wrote:It is quite difficult to interpret the bit pattern via Listen. The best way to read the data sent by the motes is through a message interface file. Like the one I generated. (Payload.java attached). You can generate this file by running make -f jmakefile (jmakefile attached). Finally call the functions from your class file like in RFID.java that I wrote. You will get an error when compiling RFID.java because I hae modified the MoteIf constructor. You can look into MoteIf.java for a list of constructors that can be used.

Unfortunately I cannot answer your question since I think it exceeds my knowledge about it. But actually I thought I was one of the fewer guys who were using it. I was wondering if we could stay in touch and perhaps help each other. May I ask you which software are you using with it? We bought our skyetek M1 mini from crossbow, and their tech support provided me with both the: \opt\tinyos-1.x\contrib\xbow\apps\SkyeReadMini2_MICA2\TestSkyeReadMini2, and \opt\tinyos-1.x\contrib\xbow\apps\SkyeReadMini2_MICA2\TestSkyeReadMini2_Poll I am using the 'poll' version since our reader doesn't have buttons. That means it keeps polling the whole time. I can get the whole stuff working, by having a TOSBase mote attached to a programming board and running the java app net.tinyos.tools.Listen, however the bit pattern I get is quite weird... I don't really understand it. Do you have any idea on how to interpret this bit pattern? Or do you use some other application to do this? Looking forward to help and contribute, regards, Pablo Guerrero Shweta Jain wrote:Hi all, I was wondering if anyone would know the voltage to db conversion formula for the RSSI value read from skyetek's M1 mini.
