Hi guys!

I have problems when i send to sleep the mote, really when it wakes up.
the flow of my program is:
1.-read sensors from agriculture board.
2.-send the data
2.-sleep for 15 mins.(deep sleep)
3.-wake up
4.-go to point 1
this work for aprox 2-3 hours and after this time the mote don't wakes up.

regards

Hi favila,

did you check the charge of the coin cell and battery? Which sensors did you connect to your board, and what version of the board do you have? Could you please post your code so we can take a look?

Regards.

The battery and the coin cell are charged. The sensor conected to the agro-board are:
-preasure
-hummidity and tempreature
-wind direction
-wind speed
-rain
-soil temperature
-leaf wetness
-1 soil moisture

mi main code is this:

Code:

void setup()
{
  int i = 0;
  xbeeZB.init(ZIGBEE,FREQ2_4G,NORMAL);
  // Powers XBee
  xbeeZB.ON();
  xbeeZB.setAPSencryption(XBEE_ON);
  xbeeZB.getOwnMacLow();
  Utils.hex2str(xbeeZB.sourceMacLow, myMac);
  delay(2000);
}

void loop()
{
  char macDest[17];
  SensorAgr.setBoardMode(SENS_ON);
  //capture the data from sensors
  readSoil();
  readWeather();
  readPlant();
  readClimate();
  toSleep();
}

and the fuction to sleep is:

Code:

void toSleep()
{
  RTC.ON(); 
  //Y:m:d:nd:H:m:s
  RTC.setTime("12:01:01:07:00:00:00");  
  // Go to sleep disconnecting all the switches and modules 
  // After 15 minutes, Waspmote wakes up thanks to the RTC Alarm 
  SensorAgr.setBoardMode(SENS_OFF);
  PWR.deepSleep("00:00:15:00",RTC_OFFSET,RTC_ALM1_MODE1,ALL_OFF); 
  if( intFlag & RTC_INT ) 
  {  
    intFlag &= ~(RTC_INT); 
  } 
}

Regards

Hi favila,

It is probably owed to a collision in the I2C bus, if you turn off the board and then use deepSleep, when trying to configure the alarm the communication in this bus may be corrupted by the non-powered devices connected to the bus on the board. If you don't turn off the board (keep also on the sensors of the low consumption group) and use function sleepAgr from the SensorAgr library the problem should be solved.

Regards.
