Sensor node not working without #define MyDebug

Last Mysensor 2.0.1-beta
2 Arduino Mini Pro (8Mhz) 3.3V version
2 NRF24l01+ with 47uF caps
Use a 3.6V LiPo battery on both setup's.
IDE 1.6.12

I use the standard GatewaySerial.ino and BinarySwitchSleepSensor.ino sketch, where the problem comes, when I disable the MY_DEBUG in the GatewaySerial.ino sketch.

I think the problem is, that the "void loop()" in the GatewaySerial.ino is empty, and the Arduino has a timing problem to the radio, as the loop is running to fast, without doing nothing. If I add delay(10) into the "void loop", it all works fine.

@tekka
Btw. Another problem. If I use the "#define MY_DISABLED_SERIAL" on my GatewaySerial.ino I still get incomming message on the serial port. Ex. temp sendet from a tempsensor here:
6;0;1;0;0,24.5
6;0;1;0;0,24.6
6;0;1;0;0,24.5
6;0;1;0;0,24.4
6;0;1;0;0,24.5

I also need the AVR board def version - you can find this information in the Boards Manager.

Well, there is no sense in disabling the serial port on a serial gateway :smirk:

BN: Unknown board

Btw. I use OpTiboot loader

So I tried to see if I make one last attempt to fix this problem again, I tried the Alex option using a delay(10) in the for loop. So I put a delay(10) in the for loop of my gateway code whoa it works fully well. I guess their is truly a timely issues here and the enable my_debug it's somehow doing a slowing things down work.
But using a delay(10) in the loop isn't really an efficient way though.

I have solved it, with the fix from Alex, with a delay(10) in the loop() :-) Thanks

UPDATE: Using a delay(1) also works for me too

[tekka]

@delinend Still not the right thing. Sorry for bugging you with that ;)

You'll find the requested information under:

In Arduino IDE under Tools | Board | Boards Manager => Arduino AVR Boards Built-in by Arduino version 1.6.xx

@tekka
It's: Arduino AVR Board Built-In by Arduino version 1.6.14 installed.

@delinend I've tried your setup but cannot reproduce your issue. Are you on the latest dev branch (from today)? What board did you choose in the settings?

Out of curiosity, please upload this sketch:

#define MY_CORE_ONLY
#define MY_DEBUG
#include <MySensors.h>

void setup() {
  Serial.begin(115200);
  Serial.println("***");
  Serial.print("V=");
  Serial.println(hwCPUVoltage());
  Serial.print("F=");
  Serial.println(hwCPUFrequency());  
  Serial.println("***");
}

void loop() {}

and post the serial output.

[delinend]

Here the output.

@delinend Ok, so you have a slightly higher voltage and frequency - this could cause some timing issues, since the sketch is compiled at 8Mhz. Can you feed 3.3V, e.g. using a voltage regulator?

[delinend]

@tekka
This is with my Lab Powersupply to 3.3V

V=3300
F=89

[tekka]

@delinend ok, and still the same with MY_DEBUG and the latest dev branch?

[delinend]

@tekka
Hmm.. It works fine without the delay(10), at 3.3V! But if I rice the voltage to around 3.6-3.7V, I have to add the delay(10) again in the void loop(). ?!?!

Btw. The nRF24l01+ is attached Vcc on the Arduino Mini Pro board.
