MySensors 1.4 Released
-
I spoke too soon...
I'm going crazy trying to find out why my sensors with DS18B20 keep locking up.... Today I had to clear and re-upload a sketch to a locked up sensor and it would not convert to F.. Severals hours later, still would not convert..

@ServiceXp
You could test some other ds18b20 library and add a capacitor on the powerline to the temp-sensors.

I now believe it's related to the DS18D20 sensor. The same sensor locked up again when I got home, and interestingly enough they locked up @ -7.0 F. both times.
- I power cycled sensor, (Still Locked Up)
- Pushed sensor reset button. (Still Locked Up)
- I removed from freezer, warmed sensor; power cycled sensor again (Still Locked Up)
- Disconnected the DS18D20 from sensor and what do you know I was able to get it to recover.
So either this is just a freak of coincidence or the DS18D20 is some how locking up the Arduino in my environment. I installed a .47uF cap between the sensors VCC and GND wires, so we shall see.
Here is the serial output of the sensor:
-
Locked up again this morning @ 7:37am with a temp of -0.1. So a .47uF cap isn't the answer....

###1.4 update 1 released
NOTE: This release does not require you to update all nodes . Nothing has changed in protocols.
- All outgoing messages from gateway included a newline character. This has now been fixed.
- The msg.getByte() wrongfully used atoi() conversion if payload was of string type.
- The getByte-bug caused problems when receiving Metric/Imperial settings from controller.
- A new sleep-method added to allow wake-up on both external interrupts.
- A new example BinarySwitchSleepSensor showing the new sleep function (thanks @Anticimex).
- Library code (RF24) reduced by 624 bytes (thanks @Damme)
- Many people has reported powering problems when using amplified version of the NRF-chip on their gateway. The Arduino Nanos 3v3 output does not seem to be sufficient for PA_MAX. The radio needs to be feeded separately with a stable 3v3 to work. Defaulting gateway PA-level to LOW now and if you are using a vanilla radio on gateway you can switch back to MAX in your MyConfig.h.
@hek Can you help me to understand how to get the update, and what parts are updated? I followed the download link to the library and installed the files. I then updated my gateway but I didn't see any version number change and I'm still having trouble with temperature readings coming through in Imperial units rather than metric.
Thanks, and keep up the great work!

Hi Hek,
Yeah from the main page, I went to the Download page and then hit the Download button under the 1.4 Latest Release section. The readme file in the archive says 1.4, but I'm looking for 1.4 Update 1 which has the fixes for the imperial vs. metric units with temperature sensors. I rebuilt my gateway with the code anyway but no change. Am I missing something?
Thanks,
Troy. -

Thanks,
Troy.Then you're using the latest 1.4 version.
You'll have to look at the debug prints on the sensor to see what is happening and determine if there's communication problem. I suspect that your sensors messages can reach the gateway but not the other way around (sometimes).

@hek I did some testing and it appeared to be a sync issue. First I looked at the gateway and the debug messages showed Imperial units which matched the Vera UI. Then I unplugged the temp. sensor from power and plugged it into my laptop and it was reporting Metric units in the debug, and then Vera started showing Metric. So I unplugged the sensor from my laptop, plugged it back into it's original location and the units switched back to Imperial. Finally I just rebooted the gateway and the sensor and now Metric is working.
Anyway, thanks for your help!

Just wondering if the gateway inclusion push-button needs an external pull-up resistor. I looked at the code (older code 1.3 something) and didn't see internal pull-ups enabled, yet in the instructions it does not mention to hook up an external pull-up resistor. Please advise...I have designed a gateway PCB with an external pull-up because I didn't see internal pull-ups enabled in the code.
