1.1.0-snapshot, still having problems...

  • After building arduino gw and moving to pi3 I still get crashes where no data is s received by MYC.
    After todays crash I stopped myc and tailed the gw - here is what I get...

    pi@HAMASS:/home/mycontroller/logs $ sudo tail -f /dev/serial0
    0;255;3;0;9;6300076 TSF:SAN:OK

    That doesn't look right to me. - Also the MYC log gives a lot of this.....

    I am guessing this is because I set the gw to use an inclusion button to stop 'rogue' nodes compromising the network?

    Pi is up-to-date with update/upgrade and firmware...

    Any ideas?

    How did you setup/wire the button? and how do things work is the button is removed?

    seems that 5 is the inclusion mode, and 0 and 1 starting/stopping
    See here

  • @Tag

    I searched on this forum for 'inclusion mode' and it says it is not supported (so the message in the above log also says the same thing). So I reflashed the gateway to remove this function.

    Once the gw and sd card were reflashed it was working agian. I also replaced the nrf with a pa/lna version to see if that would help at all.

    After doing this with it all working I stopped MYC and tailed the gw. This time I could see the sensor data (which was missing in the previous attempt with all '5''s in it - It should be there no?).

    As for wiring, the button pin was probably floating after I triggered it. Maybe something to look into, but for now I have a relay to try and get working.

    Thanks as always! 🙂

    @skywatch 👍
    (Floating pins can get you strange readings) Good you see the sensor data now!! 🙂

  • Happened again yesterday - won't post log as it's pretty much the same.

    This time I was able to recover by powering off the pi and gw arduino, waiting 30seconds and then powering up again. So far it's all running fine again!

    I may add some capacitors to help stabilise the power for the pi and arduino and see if that helps. I do have one node that 'sometimes' needs to be rebooted when it stops working. Again it may be power related. We'll see on that... 😉

  • MOD


    did you update the arduino with the gateway sketch without the inclusion button stuff?

    should be commented out in either your sketch or in mysensors.h

    // Enabled inclusion mode feature
    // Enables inclusion-mode button feature on the gateway device
    // Set which pin you have the inclusion button attached to
    // Set inclusion mode duration (in seconds)

    How do you power your rpi?

  • Hi @Tag

    Yes I did remove the inculed button as I could not get it to work and stability is what I really need right now.

    Rpi3 powered from a 5v 3A switchmode psu. Should be plenty for what it is doing...

    The GW is currently using 2.2.0-beta and tomorrow I will update to 2.2.0-rc1 and see if that helps at all. I am reflashing nodes using 2.2.0-rc1 tomorrow as well, but have a couple of new ones that are driving me mad (still a lot to learn it seems) 😉

  • MOD


    Did you only remove the hardware, or also the inclusion button stuff from your sketch?
    It might be that just removing the hardware is not enough....

    Your power supply with 3 amps should be enough have you ever tested another, sometimes the 5v coming from cheap wall plugs is not that clean... (not saying yours is cheap!!)

    for what it is worth, i use a mix from 1.5x to 2.2x it works great up until now... but you can always try...

    The nrf's you are using, are these with the "real" chip on it, or do you use the ones with a black round "blob" on them? I am asing, since i received these once and they gave me all kinds of issues....

    Keep going!, and keep us posted!!
    good luck!

  • @Tag

    It stopped getting data again just after 4.10AM this morning....

    I don't really believe it is power supply problem. The 'internal' data still continues to flow without issue, just the rf side stops suddenly without reason. Also, I can still SSH in and do whatever I need to without problem. A psu issue would probably crash the entire pi, not just one data source.....

    The pa/lna I have not seen with COB yet (the blob) - and no I don't have any with 'blobs' on them! 😉

    Inclusion mode, I removed it all from the sketch and the associated HW. I will re-flash the GW today and post here exactly the code that goes into it. I may also try another pro-mini and this time solder to the board instead of adding dupont connectors, they can often be a pita! 😮 🙂

  • MOD


    Ah the pa/lna's are very very power hungry!!

    Look at this thread, i have also read something about putting the radio on the 5v rail using a a stepdown converter that gets you from 5v to 3.3v.

    Changing the power settings in mysensors.h is also an option

    ifndef MyConfig_h
    #define MyConfig_h
     * Configure Sensor Network
    #define RF24_CHANNEL	   76             //RF channel for the sensor net, 0-127
    #define RF24_DATARATE 	   RF24_250KBPS   //RF24_250KBPS for 250kbs, RF24_1MBPS for 1Mbps, or RF24_2MBPS for 2Mbps
    #define RF24_PA_LEVEL 	   RF24_PA_LOW    //Sensor PA Level == RF24_PA_MIN=-18dBm, RF24_PA_LOW=-12dBm, RF24_PA_HIGH=-6dBM, and RF24_PA_MAX=0dBm
    #define RF24_PA_LEVEL_GW   RF24_PA_LOW  //Gateway PA Level, defaults to Sensor net PA Level.  Tune here if using an amplified nRF2401+ in your gateway.
    #define BASE_RADIO_ID 	   ((uint64_t)0xA8A8E1FC00LL) // This is also act as base value for sensor nodeId addresses. Change this (or channel) if you have more than one sensor network.

    #define DEFAULT_CS_PIN 10

    Thanks for your input and suggestions....

    RE: Radio - I tried with 2 different 'normal' radios with the printed antenna first. Still had the problem.
    I moved to the pa/lna in a desperate attempt to see if it would help.
    The current module gets it's power from a 662k regulator (with caps). Source is the 5V out and gnd on the pi. So should be plenty of available power for this board. The RF also has it's own 47uF cap directly soldered to the power pins (small smt tantalum rated at 6.3V).
    In the code the level is set to #define RF24_PA_LEVEL RF24_PA_LOW - So again should be no problem.
    The RF module is about 10cm+ away from the pi too....
    Here is the full gw sketch added today with the latest dev branch freshly downloaded this morning....

    // Enable debug prints to serial monitor
    #define MY_DEBUG
    // Enable and select radio type attached
    #define MY_RADIO_NRF24
    //#define MY_RADIO_NRF5_ESB
    //#define MY_RADIO_RFM69
    //#define MY_RADIO_RFM95
    // Set LOW transmit power level as default, if you have an amplified NRF-module and
    // power your radio separately with a good regulator you can turn up PA level.
    #define MY_RF24_PA_LEVEL RF24_PA_LOW
    // Enable serial gateway
    // Define a lower baud rate for Arduino's running on 8 MHz (Arduino Pro Mini 3.3V & SenseBender)
    #if F_CPU == 8000000L
    #define MY_BAUD_RATE 38400
    // Enable inclusion mode
    // Enable Inclusion mode button on gateway
    // Inverses behavior of inclusion button (if using external pullup)
    // Set inclusion mode duration (in seconds)
    // Digital pin used for inclusion mode button
    // Set blinking period
    // Inverses the behavior of leds
    // Flash leds on rx/tx/err
    // Uncomment to override default HW configurations
    #define MY_DEFAULT_ERR_LED_PIN 4  // Error led pin
    #define MY_DEFAULT_RX_LED_PIN  6  // Receive led pin
    #define MY_DEFAULT_TX_LED_PIN  5  // the PCB, on board LED
    #include <MySensors.h>
    void setup()
    	// Setup locally attached sensors
    void presentation()
    	// Present locally attached sensors
    void loop()
    	// Send locally attached sensor data here

    This is exactly what is in the gw.....

    I have also put multiway connectors on the dupont cables as it should add more mechanical stability (just in case something happens with the wiring) - But again this would not explain why a power cycle gets it all going again... ???
    Lets see how it goes now again.

  • Well this is strange indeed.

    Last night all rf nodw data stopped arriiving at the controller again.

    This time I simply power cycled the arduino gw and 50% of nodes started to display data again.

    After half an hour this was still the case so I stopped and then started again MYC (no power off on the pi at all). Suddenly the remaining nodes started to show and this morning it's still looking good.

    I'm still struggling with why this happens, especially as this would indicate it is neither the gw arduino or controller pi that is solely responsible.

    Any ideas out there???

    Weird, but it seems to narrow down to the arduino + radio...
    Have you seen this link, looks like the same iss you experience....

  • Which is kind of ironic as I moved to that setup due to the same issues with pi attached directly to radio. 3 different radio modules tested as well....

    I will keep the external gateway as it allows for hardware signing for secure messages.

    It doesn't narrow it down like that to me since it needed the myc controller to restart as well before things got back to normal.

    /Maybe I'll add a hardware watchdog of some type, but it's difficult to decide what action it should take.

    I noticed that there was no final solution on the mysensors site either. I wonder if it was ever resolved??

  • @skywatch Do you have ESP8266 module? If yes you may give a try for WiFi/MQTT.

  • Thanks -

    I now have made a new build of this. New arduino pro-mini (3.3v 8MHz), rf24 PA/LNA soldered to pro mini. Brand new 32Gb Sandisk SD card flahsed with latest raspbian (updated and upgraded) - Latest mycontroller 1.1.0-SNAPSHOT - Latest mysensors 2.2.0-rc.1 ......The result?

    Now I can't see any nodes at all! - I have tried to think what might be happening here.

    If I attach the arduino gw to the laptop and check in serial monitor I see data arriving from the sensors, so that looks to be working. But when I attach it to the pi I get nothing.
    MYC shows the gw serial connection as 'connected successfully', so where/what am I missing here?

    In raspi-config I selected serial = on ; serial console = off. I think thats right....?

    So the story continues..... since the promini does not have a USB port, how is it connected to the PI?

    What is the output of:

    stty < /dev/<YOUR-DEVICE-FILE>

    Change <YOUR-DEVICE-FILE> with the device file you are using....
    It might be that it is set to 9600baud, while mysensors talks at 115200baud...

  • @Tag

    pi@HAMASS:~ $ stty < /dev/serial1
    -bash: /dev/serial1: Device or resource busy

    Connection is from pi serial port to promini serial port. That's how it has been since I had to abandon the radio attached directly to pi version. I also added a brnad new raspberry pi 3 today as well....so eliminating hardware as much as possible.....

    I have even taken one node and cleared the eeprom and reflashed with the sketch and still I get gw connected but no nodes showing. This is driving me nuts!

  • @skywatch Can you try putty or some other tool to monitor serial port on your Raspberry PI?

  • MOD


    Prior to running the stty command, did you stop mycontroller?

    The reason that you do not see any data comming in is most probably due to the fact that mycontroller locked the port...

    If you do not see anydata comming in it might be that mycontroller is listening at the wrong baud rate, are you using 115200 baud in mycontroller for your gateway?

    This is my setup:
