RAK4631-Lora P2P TX to send every 1hour and go back to sleep mode

WisBlock
#1

Hi there,

i’am beginer to Lora communication.we bought rakwireless wisblock kit-2 module. and i tested sample code given in rakwireless library in arduino. lora p2p communication [TX/RX] .All the task are working fine. Now i’ve to modify the code to send the 4 byte data packets every 1hour and go back to sleep mode and this process should be repeated. can any one help me for arduino firmware support

For such a task, there is a real-time clock module
with wake on interrupt RTC Module Micro Crystal RV-3028-C7
It is important to note here that the RAK12002 module has the ability to work with interrupts - this is a very important feature for your task.
RAK12002 is a WisBlock (RTC) Real-Time Clock module based on Micro Crystal RV-3028-C7 which has its own battery backup via super capacitor.

All you need to do is program the watch’s internal alarm clock to wake up every hour (the Melopero_RV3028 libraries have all the functions).
Of course, this should put the microcontroller into sleep mode after waking up.
Here is how it is implemented in the library examples.

// set the interrupt to trigger every day at 1 minute from now
// since we set the hour to 15:20 we don't have to check if the 
// minute value exceeds 59...
  rtc.setDateModeForAlarm(false);
  rtc.enableAlarm(/* weekdayOrDate not important */ 0, /* hour */ rtc.getHour(), /* minute */ rtc.getMinute() + 1,
            /* dateAlarm */ false, /* hourAlarm */ true, /* minuteAlarm */ true, /* generateInterrupt */ true);

  // setup the pin to listen for the interrupt
  pinMode(intPin, INPUT_PULLUP);
  attachInterrupt(digitalPinToInterrupt(intPin), interruptCallback, CHANGE);

Успехов!
