[Problem:
I m using SimpliciTI stack with EZ430-RF2500 development kit. I have modified simple link-listen sample application. Instead of blinking LEDs I m issuing ping requests. I have written the code for wake on radio functionality as per application not - AN047. Following are the setting I am using for various registers MCSM0 0x18 MCSM2 0x01 WOREVT1 - 0x01 WOREVT0 - 0xF1 WORCTRL - 0x78 IOCFG2 - 0x06 Also have configured GPIO pin 2.7 of microcontroller to Rising eadge interrupt. Then I m issuing SWOR strobe to put radio in WOR mode. Note : Before putting radio in WOR mode I have linked it to another radio unit (Same as is done in Link-listen application) I m sending stream of packets from another device to wake-up the radio from WOR mode. With this I am getting the interrupt on the microcontroller from the CC2500 GDO2 pin. I am then issuing the idle strobe to come out of WOR mode. And then putting the radio in RXon mode so that it can respond to the further packets. But after this the Radio is showing no activity. It is not responding to the ping requests send to it any more. I also tried flushing the Rx buffer by calling RxIdle but it didn't work Please reply ASAP. ]
