I have now implemented the changes discussed here. It now seems to work flawlessly. I tested the node to see its behaviour when i powered down the gateway. As it said in the thread the node tried to reconnect after a couple of failed transmissions. And when I powered up the gateway again the node reconnected and started to go to sleep again.

Thanks for the help on this.

A Quick question a bit of topic Before I go build new nodes. If I want to run the cpu at only 1 MHz, do I have to do something else other then define the cpu frequency in the sketch? Is it possible to set the cpuclk prescaler at runtime?

@tekka Updated arduino to latest version 1.6.11 and downgraded to boarddefs 1.6.11 and now it seems fixed, at least with softspi for the radio.
I have to try it with hwspi some other day. Have to stop for today.

The version of arduino 1.6.9 would not let me downgrade to boarddefs 1.6.11, thats why it did not work when I tryed it before.

Thanks for all your help.

@AWI

Thanks for your reply and tips to a beginner.

I experimented with a couple of things in the sketch and after a little digging I seem to have got it working.

The problem seem to be that if the values sent to the gateway is not in the correct format it wont work. If I send just one value in integer it works. But if I send alla three values as integer it stops working. If I send all three as "double" with two decimals it works as it should.

The sketch when it functions as it should:

I have a node that is causing problems for me. When I have the node and the gateway in the same room all works fine. But when I move them apart the node stops sending the messages after a random couple of hours. This I think is because of the range. But if I move the node closer to the gatway again it doesn't reconnect. And the debug from the node outputs:

!TSP:SEND:TNR
!TSP:SEND:TNR
!TSP:SEND:TNR
RF24:write register, reg=0, value=12
RF24:power down

and repeats until I reset the node.

It seems that my auto reset of the nod fails also.

The sketch looks like this:

What does the message:

!TSP:SEND:TNR

mean and how do I handle it?

@mfalkvidd After Little more investigating and experimenting I am pretty sure I have found a bug in the library. I found that when debug is active all is working as expected. But if I commented out debug it starts to not work. I tried it about 10 times, once with debug and then without. And everytime debug is active it works, no debug it fails.
I opened the transport sourcefile and added a delay(100) at the procedure where the debug message is sent. With that change it works everytime with or without debug. It seems that if the ackmessage is sent to quick it gets missed by the gateway. Any thoughts on this?

I'm having trouble to log the node since it is in a remote place when it stops working.

Can you please explain a little more what you mean with "send the node to sleep before the communication is fully re-established"?

I'm a bit lost in all this it seems. I must have missed someting when reading about sending new values to the controller. But I thought that when the "send()" is executed the program is waiting here until Everything is finished for that transmission and we can move on to the transmission.

Is there something I must do before sending the cpu to sleep?

Sorry for my slow understanding.

@novicit If I remember correctly i put it here: https://github.com/mysensors/MySensors/blob/master/core/MyTransport.cpp#L463
just to test that it worked. Then I removed the change to keep the library source original.

I turned on debug again to get it working again.. The reason why I wanted to have debuging disabled was to keep the hexfile size down so the OTA update wouldn't take so long time. I hope this issue will be fixed in a more elegant manner in a future release.

@AWI thanks for clarifying. I will read up on the subject. Strings i C is not my favourite subject.

The pinchange interupt works fine.

I found the offending things on my board. It was a combination of a couple of things. First it was the BME280 that was constantly active. Change to forced mode dropped the consumption from 0.4mA to 0.1 mA. I stopped using the internal pullup for my windspeedsensor which is based on a reedswitch. I noticed when the switch was open the consumption dropped to 0.04mA so I mounted a 1Mohm resistor instead of the internal pullup. Turning off the ADC dropped a about 10-20 uA. And lastly it seems that my nimh batterys where bad. They could not keep the charge. Changed to 2 x aaa and now it looks better.

Current now on average 0.035 mA in sleepmode

I will buy new nimh's to see if my solar panel circuit will work as expected. I hope to keep it running for about 5 years without changing the battery.
Only time will tell now.

  if (pinchange){     //Om pinchange är anledningen till vakna så sov igen
    pinchange=false;
    goto sleep;
  }

  asm("cli");

  sendfail();
  asm("cli");
  cycle=TCNT1;
  asm("sei");
//  Serial.print("Cykeltid: ");
//  Serial.println(cycle*8);

But it seems to consume to much power.

The pinchange interupt fires fairly often but the mcu is mostly awake for about 120 cycles every second. So a drop of 0.2 Volts in battery in under 18 hours seems a bit high. This on a 3.3v pro mini at 8MHz.

@mfalkvidd
I will look into using your suggestions when I have the time.

Regarding using my code in the library I don't see it beeing an option. The reason is that I'm an amateur programmer and as such I dont know all the "rules" on how code should look. In swedish as you know we have the term "spagettikod" and thats kind of how my code looks. I'm from an assembler background and and there I'm used to "slap some thing together", poking in registers directly and such.

I'm having trouble with high current consumption in an battery operated node. I suspect the NRF beeing the offending part. How can I be sure I have put the radio to sleep? I don't use the sleep() command because I use pinchange interupt instead of INT0 or INT1. I put the cpu to sleep with my own code. But how can I be sure that the radio has been put to sleep?
In the code as it is now I use,

transportPowerDown();
asm("SLEEP");

But I'm not sure that the radio is put to sleep.

Excuse me for beeing an idiot. But how do you compile the bootloader from source? Do you do it from Atmel studio or from Arduino IDE. And how is it done? When I compile it in Atmel studio it gets an base adress of 0x0000 which is wrong.

I am used to program in assembler in Atmel studio and when I program in C i don't touch anyting else than the .c file. So some form of tutorial kind of thing would be helpful.

Thank you

@novicit If I remember correctly i put it here: https://github.com/mysensors/MySensors/blob/master/core/MyTransport.cpp#L463
just to test that it worked. Then I removed the change to keep the library source original.

I turned on debug again to get it working again.. The reason why I wanted to have debuging disabled was to keep the hexfile size down so the OTA update wouldn't take so long time. I hope this issue will be fixed in a more elegant manner in a future release.

I have also problem with speed of the upload. I get about 1 packet per 3 seconds. Is there a something in the code for the bootloader that has a waitingtime of 3 seconds? And if so, because of what? From that info we might be able to tell if it's a reception problem of the node or the gateway.

@mfalkvidd After Little more investigating and experimenting I am pretty sure I have found a bug in the library. I found that when debug is active all is working as expected. But if I commented out debug it starts to not work. I tried it about 10 times, once with debug and then without. And everytime debug is active it works, no debug it fails.
I opened the transport sourcefile and added a delay(100) at the procedure where the debug message is sent. With that change it works everytime with or without debug. It seems that if the ackmessage is sent to quick it gets missed by the gateway. Any thoughts on this?

Having checked the serial output from the new node at my computer I see that the library returns the command when a ACK i requested. I also looked in the sourcecode for the library and it seems that it handles the ackmessage.
So it seems that the ACK message get missed in the recieving node. Why, is the next question.

Investigation continues...

I put together another node exactly the same but keeping it at my workbench roughly the same distance from the gateway. It works without any troubles so far. The only change in the sketch is the node id and no ds18b20 temperature reading.
The log from myscontroller show that it works even if the node doesn't send back the same status as the command. Domoticz doesn't complain as it does with the first node. This behaviour was last night.

Now this morning the replys from the new nodes is also present. They weren't last night. At least not in the logs from MYScontroller.

When domoticz sends a switchcommand to the gateway it does so with with ACK flag set. Does mysensors library automatically reply?
I haven't programmed in a replyfunction in my sketch so it seems like it. But in that case why doesn't my first node reply every time?

Strange. Have to investigate this further.
