[Tinyos-help] GenericComm fails when an event is fired
hi all, i have a problem. In my program, my GetPressure component requests ProvidePressure component to start and get pressure data. when the Pressure.dataready event is fired in the ProvidePressure component, in this event another event is signalled to the GetPressure component that tells that the data was collected and is sent as a parameter to the event. Now we are able to receive this event in the GetPressure component but when we try to use GenericComm.send, it returns successful but does not signal the SendDone event. Please can somebody throw sum light on this issue. Thank You -- - - Regards, Prajakta Choudhari, Project Engineer ___ Tinyos-help mailing list Tinyos-help@Millennium.Berkeley.EDU https://mail.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
[Tinyos-help] MTS420 GPS receiver
Dear all: i am building an application using mts420 gps receiver that keeps on receiving gps packets till it gets a valid gps packet. As soon as the valid packet is received, the application shud glow red light and stop forever. It seems that the gps does not work without a timer. So i have used 2 timers. On the event of the first timer fired the gps is powered . On the event of the second timer fired the gps txrxswitch is enabled. Then the application starts receiving gps packets. On receiving a valid gps packet i have called call GpsCmd.TxRxSwitch(0); call GpsCmd.PowerSwitch(0); to stop gps receiver. But still after the receiving a valid gps packet it,doesn't stop. It starts the ONE_SHOT timers again..and the cycle repeats. I am attaching my code.. It would be really gr8 if somebody throws light on this issue. Thank You.

[Tinyos-help] Help regarding MTS420 GPS receiver
Hi all.. I am trying to write a simple program for MTS420 GPS sensor. The program shud initialise and start the GPS receiver and store the readings in the variables defined. But i am unable to start the GPS receiver. The GPS Receive packet event is not generated. Is their any special way yo initialise the GPS receiver. Can i get a sample code apart from the XMTSensor420 provided by xbow.. Thank You in advance. -- - Regards Prajakta ___ Tinyos-help mailing list Tinyos-help@Millennium.Berkeley.EDU https://mail.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help

[Tinyos-help] Receiving packets from the base station
Hi all.. thank you Mr.Michael Schippling for u r previous response. I was able to send a packet from pc to gateway. We have modified TOSBase such that whenever it receives the request packet from the pc it sends back a response packet to the pc over uart and also broadcasts the request packet on the radio. The request packet that is send to the base station requires acknowledgement. 7e 41 01 ff ff 09 7d 5d 02 00 00 08 bf 7e But when we sent the packet,it is received byTOSBase,broadcasted by the TOSBase over the radio , but the acknowledgement is not shown up on the PC. The PC side tool is a java program using javax.comm apis ,to send and receive packets over COM1 port. If we send 5 request packets , only one acknowledge token is printed on the screen along with the second packet's ack. token first 2 bytes. Output on the pc side tool: 5 packets sent succesfully to gateway 7e 40 0f ed 73 7e 7e 40 I am confused whether the problem isin the java code or in the TOSBase Thank you -- --Regards,Prajakta Choudhari,Project Engineer, ___ Tinyos-help mailing list Tinyos-help@Millennium.Berkeley.EDU https://mail.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
