I want make wireless system with MC13191. My thesis is to accomplish wireless communication between PC and sensors on human body. I read all reference manual but I want be sure in few facts about MC13191's possibilities.</SPAN><BR /><BR /><SPAN>1. Does it true that MC13191 can not support full-duplex communication, and there is no possibility to accomplish its in any way? Undoubtedly, I saw state diagram in reference manual, and from it I saw that MC13191 support only half-duplex communication.</SPAN><BR /><BR /><SPAN>2. Can I accomplish "imaginary" full-duplex communication by manipulating with packet RAMs?</SPAN><BR /><BR /><SPAN>3. If there is no possibility to accomplish full-duplex, where can I find information about MC13191 in star network. I would use one master MC13191 and eight slaves Mc13191s in star configuration. Does MAC software offer that possibility or I should use special protocol for that type configuration?</SPAN><BR /><BR /><SPAN>In fact, my problem is what I need realize real-time system. I had decided for MC13191 because its high data speed (250kbit/s), low power consumption and in the first revision of reference manual someone had wrote state diagram that had showed transition between Rx state and TX state without IDLE state. In other revisions that was changed.</SPAN><BR /><SPAN>If I would not accomplish anything in above questions, I must find other chip. </SPAN><A href="http://freescale.i.lithium.com/i/smilies/16x16_smiley-sad.gif"><IMG alt=":smileysad:" class="emoticon emoticon-smileysad" src="http://freescale.i.lithium.com/i/smilies/16x16_smiley-sad.gif" title="Smiley Sad" /></A><BR /><BR /><SPAN>Thank you very much!</SPAN><BR /><BR /><SPAN>Best regards,</SPAN><BR /><BR /><SPAN>Josko</SPAN></BODY></HTML> Tue, 14 Nov 2006 22:43:54 GMT https://community.nxp.com/t5/8-bit-Microcontrollers/Developing-applications-with-MC13191/m-p/136552#M4391 MC13191 2006-11-14T22:43:54Z Re: Developing applications with MC13191 https://community.nxp.com/t5/8-bit-Microcontrollers/Developing-applications-with-MC13191/m-p/136553#M4392 <HTML><HEAD></HEAD><BODY><DIV>&nbsp;</DIV><DIV>In&nbsp;the strictest definition it is only Half-Duplex since send and receive are on the same RF channel, but from the users point of view it is FULL-DUPLEX, since ZigBee and IEEE802.15.4 use a CSMA-CA (Carrier sense multiple access with collision avoidance) channel access mechanism.</DIV><DIV>&nbsp;</DIV><DIV>Even in fairly busy networks, data can be sent a received almost instantaneously.</DIV><DIV>&nbsp;</DIV><DIV>Regards,</DIV><DIV>&nbsp;- Ware</DIV><DIV>&nbsp;</DIV></BODY></HTML> Wed, 15 Nov 2006 00:47:43 GMT https://community.nxp.com/t5/8-bit-Microcontrollers/Developing-applications-with-MC13191/m-p/136553#M4392 Ware 2006-11-15T00:47:43Z
