I would appreciate help on a problem with my code derived from the Mayfly-sleep.ino example. I am using the SoftwareSerialMod.h library as recommended to resolve a pin conflict. However, when I activate myserial.begin(9600) the program does

not
go into sleep mode.

/* This example sketch puts the Mayfly board into sleep mode. It wakes up at specific times, records the temperature and battery voltage onto the microSD card, prints the data string to the serial port, and goes back to sleep. JOM 2/9/17 added power on/off to EZO board JOM 2/12/17 downloaded ...Mod.h libraries to fix RTC interupt conflicts. Need to turn off rx and tx when putting to sleep otherwise rx/tx powers the sensor after Vcc is turned off JOM 2/13/17 Problem sensor on most of time. may need to serial.flush JOM 3/12/17 problem was not plugged into grove 10/11 socket!! JOM 3/13/17 does not go to sleep even with minimal EZO code JOM 3/14/17 activating myserial.begin(9600) causes sleep mode not to work. */ #include <Wire.h> #include <avr/sleep.h> #include <avr/wdt.h> #include <SPI.h> #include <SD.h> #include <SoftwareSerialMod.h> #include <RTCTimer.h> #include <Sodaq_DS3231.h> #include <Sodaq_PcInt_Mod.h> RTCTimer timer; #define rx 11 //D11 to Tx on EZO (white on Grove conn) #define tx 10 //D10 to Rx on EZO (yellow on Grove conn) SoftwareSerialMod myserial(rx, tx); //define how the soft serial port is going to work.
