Modifying the Wireless Sensor Monitor Embedded code to work with Low-Power PEH

1. The Wireless sensor Monitor program only runs on Windows-XP. Sometimes it can work in latest windows OS but after disconnect, it might not reconnect and you can have inconvenience in troubleshooting.
2. Start IAR Embedded workbench 5.60.7
3. Extract Slac139g.zip into a folder and open it as workspace in IAR.
4. Open the Go to menu; Project --> Edit Configuration. And choose "CC2500 Sensor Demo-End Device"
5. Go to menu; Tools --> option --> Editor. Click the checkbox "Show line numbers"
6. In workspace, open the following file: Sensor-Cemo_AP_as_Data_Hub-CC2500 Sensor Demo-End Device --> Applications --> End Device --> main_ED.c
7. In main code, set TACCR0 to 60000, the time delay is now set at 5 seconds, the previous value will set it at 1 sec.
8. Comment the following code as below in while (SMPL_SUCCESS != SMPL_Init(0)) to save power in LED turn ON and OFF
   1. //BSP_TOGGLE_LED1(); //Hamid: comment to save power
   2. //BSP_TOGGLE_LED2(); //Hamid: comment to save power
   3. /* LEDs on solid to indicate successful join. */
   4. //BSP_TURN_ON_LED1(); //Hamid: comment to save power
   5. //BSP_TURN_ON_LED2(); //Hamid: comment to save power
9. Comment the following code as below in static void linkTo() to save power in LED turn ON and OFF
   1. //BSP_TOGGLE_LED1(); //Hamid: comment to save power
   2. //BSP_TOGGLE_LED2(); //Hamid: comment to save power
   3. /* Turn off LEDs. */
   4. //BSP_TURN_OFF_LED1(); //Hamid: comment to save power
   5. //BSP_TURN_OFF_LED2(); //Hamid: comment to save power
10. Following changes are to reduce the Power Consumption of the wireless Transceiver CC2500. It will also result in the reduced data communication distance between End_device and AP. Define new Power Level of the Tx in mrfi_fif2.c file. The values in the table are from low to high. The default settings set 3 values: -20 dBm, -10 dBm, and 0 dBm. The default at startup is the highest value. I swap the values, so the default is the lowest value always.
    1. In workspace under Components --> mrfi--> Output folder --> mrfi_f1f2.c change the following
       • #if defined( MRFI_CC2500 )
       • static const uint8_t mrfiRFPowerTable[] =
       • {
       • 0xFE, // I swept the lower and highest values in the table, so the default Power is always Lowest
       • 0x97,
       • 0x46
       • };
    2. In the main_ED.c--> main code after BSP_Init() add following lines
       • /* Set desired output power */
       • sCurrentPwrLevel = MAXIMUM_OUTPUT_POWER;
       • /* IOCTL_ACT_RADIO_SETPWR is defined in nwk_ioctl.c */
       • SMPL_Ioctl( IOCTL_OBJ_RADIO, IOCTL_ACT_RADIO_SETPWR, &sCurrentPwrLevel);
