Sudden extreme battery drain [SOLVED]

Strixx

So now I have been investigating some more. I tried to upload my own sketch again, but that made no difference. The constant power consumption was still there. So I then took the example code from the homepage and did some small adjustments and tried again.
It still consume power even when sleep. But now my meter only shows a constant 26-28 mA.

Here is the code that I use now:

#define MY_DEBUG  // Enable debug prints to serial monitor
#define MY_SPLASH_SCREEN_DISABLED  // Save memory
#define MY_SECURITY_SIMPLE_PASSWD "secret"  //Simpel soft signing with password
#define MY_SIGNING_SOFT_RANDOMSEED_PIN A3  // Unconnected analog pin for random seed
#define MY_RADIO_NRF24
#define MY_RF24_CHANNEL 110  // Set the frequency to channel 110 (2,510MHz), to prevent interference with all available WiFi channels (ch 14 -> 2,495MHz)


#include <SPI.h>
#include <MySensors.h>  
#include <DallasTemperature.h>
#include <OneWire.h>

#define ONE_WIRE_BUS 3 // Pin where dallase sensor is connected 
#define MAX_ATTACHED_DS18B20 1
unsigned long SLEEP_TIME = 30000; // Sleep time between reads (in milliseconds)
OneWire oneWire(ONE_WIRE_BUS); // Setup a oneWire instance to communicate with any OneWire devices (not just Maxim/Dallas temperature ICs)
DallasTemperature sensors(&oneWire); // Pass the oneWire reference to Dallas Temperature. 
int numSensors=0;
bool receivedConfig = false;
bool metric = true;
// Initialize temperature message
MyMessage msg(0,V_TEMP);

void before()
{
  // Startup up the OneWire library
  sensors.begin();
}

void setup()  
{ 
  // requestTemperatures() will not block current thread
  sensors.setWaitForConversion(false);
}

void presentation() {
  // Send the sketch version information to the gateway and Controller
  sendSketchInfo("pool", "2.2");

  // Fetch the number of attached temperature sensors  
  numSensors = sensors.getDeviceCount();

  // Present all sensors to controller
  for (int i=0; i<numSensors && i<MAX_ATTACHED_DS18B20; i++) {   
     present(i, S_TEMP);
  }
}

void loop()     
{     
  // Fetch temperatures from Dallas sensors
  sensors.requestTemperatures();

  // query conversion time and sleep until conversion completed
  int16_t conversionTime = sensors.millisToWaitForConversion(sensors.getResolution());
  // sleep() call can be replaced by wait() call if node need to process incoming messages (or if node is repeater)
  sleep(conversionTime);

  // Read temperatures and send them to controller 
  for (int i=0; i<numSensors && i<MAX_ATTACHED_DS18B20; i++) {

    // Fetch and round temperature to one decimal
    float temperature = static_cast<float>(static_cast<int>((getControllerConfig().isMetric?sensors.getTempCByIndex(i):sensors.getTempFByIndex(i)) * 10.)) / 10.;

    if (temperature != -127.00 && temperature != 85.00) {

      // Send in the new temperature
	  send(msg.setSensor(i).set(temperature,1));
	  Serial.print("Temperature sent: ");
      Serial.println(temperature);
    }
  }
  Serial.println("Sleep");
  sleep(SLEEP_TIME);
  Serial.println("Back from sleep");
}

And this is the serial output:

gohan

did you try to run a clear_eeprom sketch from the mysensors examples? Or burn an optiboot bootloader?

Strixx

@gohan Nope. But I tried that now, and then the sketch above again. Still the same.

sundberg84

@strixx if you removed sensors like suggested above and you still have a high mA you should try to change the pro-mini. It could be a failing capacitor leaking.

Your logs look fine.

Strixx

@sundberg84 Yes. I think I will have to do that.
I changed the test code above a little bit and added a delay for 5 seconds before sleep. And now I got better readings from my meter. It is about 48 mA when not sleeping and 28 mA when sleeping. So it does go to sleep but it is leaking somewhere.

To bad I don't have time this week for changing the arduino. I will have to get back next week about the progress.

Strixx

So. Forgot to get back.
But it was the Arduino it self that had gone bad. I switched the Arduino to a new, and everything was back to normal.

gohan

I had reports about switching to a different bootloader (like minicore) solved similar issues, as the stock bootloader sometimes doesn't like the sleep state

bjacobse

@strixx
so did you change the IC ATmega328P or was it the whole Arduino board?
if it's the whole Arduino board, then Sundbergs suggestion that a cap is faulty quite likely the error

quote Sundber84: "

Strixx

@bjacobse
Changed the whole board. I have it laying here in my workshop, but haven't got the time yet to investigate more.
It's shore sounds like @sundberg84 was right about a leaking capacitor.

Strixx

@gohan Well. I could try that. But it sounds strange to me that it will all the sudden change behavior. It was running fine without battery drain for a couple of weeks, and then all the sudden started draining the batteries.

gohan

I had a pro mini running fine for months in my outdoor solar sensor but I had to replace it as it was no longer working, with led flashing all the time. Later I managed to recover it by replashing bootloader and sketch again.

Strixx

@gohan Ok. Then I will try your suggestion. I will first have to learn how to replace the bootloader.. :-)

bjacobse

@strixx
Yes please try to update the bootloader first- I think it's quite interesting for the rest of us what is the actual rootcause
I don't use the stock bootlader in any Arduino codes, but instead an optiboot from GertSanders (as optiboot have enabled the WTD/watchdog)
https://forum.mysensors.org/topic/3261/various-bootloader-files-based-on-optiboot-6-2

Strixx

@bjacobse So it's time for a new raid with this project. I have been trying to read up on how to change bootloader. And if I understand it correct I need a programmer. And I only have a FTDI for uploading my code to my arduinos.
But somewhere I found that I can use a Arduino Uno instead.

So is this correct? If I buy a Uno will I be able to change to the new bootloader?

mfalkvidd

@strixx you can use almost any Arduino. Instructions are available at https://www.arduino.cc/en/Tutorial/ArduinoISP

Strixx

@mfalkvidd Thanks! Don't think I found that page before. Found a lot of pages about this subject but not this page. But if I understand it correct I still need to buy a new Arduino. I only have a big supply of Pro Minis. No other models.

mfalkvidd

@strixx a Pro Mini should work. It has the same mcu (atmega328) as the Uno, and pins 10-13 are available.

Strixx

So I have been reading up alot. And yesterday I finally managed to upload a new bootloader to this ProMini. It was the optiboot that @bjacobse linked to. All worked fine without any errors.

But I must have been doing something wrong, because I am not able to upload any sketch to the Arduino after that. I only get not in sync errors.

Unfortunately I don't have time to continue on this until late next week...

Yveaux

@strixx make sure you flash the correct bootloader for the crystal frequency of your pro mini (3.3V 8Mhz vs 5V 16MHz) and select the correct pro mini target in the Arduino IDE. Any errors will cause baudrate deviation in the serial bootloader communication, causing sync errors.
