@hek thanks, Now I understand.
I was poking around near that file before, but could not figure it out.
Thanks again,

Received a new ferrite bead and soldered it to my device. The bead showed 0 ohm with a multimeter so I don't know if it is the real deal but it seems to work even if it is not pretty:

[tbowmo]

at DC it should be close to 0 ohm, but on higher frequencies it should act as a resistor.

btw. it seems like the old one had exploded? :)

That's what happens when you short Vraw to GND on the MYSX connector in one of those facepalm moments :D (we need an :facepalm emoji!).

I have a lot of problem with this gateway. First I think it was caused by network module but with serial sketch I have a lot of issues. After 2 or 3 days, gateway crash. If I remove some sensors reporting every 30 seconds it crash but later.
This morning, all leds are off on the board. After powering off and on it was ok.
I'im using RFM69 with Openhab2 as controller.
Is someone experience same issue ? I will fall back to my old Jeelink gateway (ATmega328 based).

[tbowmo]

I have used my sensebender gateway for more than a year now, only difference is that I use NRF24 radio.. Haven't had any hickups yet..

Which version of mysensors are you using?

[Fabien]

I'm using version 2.1

[tbowmo]

@Fabien

Could you try the latest dev, and see how that behaves?

[Fabien]

@tbowmo : with wich RFM69 driver ?

[tbowmo]

@Fabien legacy, unless you would reflash all your nodes with the new driver as well. (they are not compatible)

[Fabien]

@tbowmo : Just flash my SBGW today with arduino 1.8.5, last boards.txt and dev branch of mysensors.
We will see if it's more stable. All my Node still in 2.1.1

Which driver to use on Ubuntu 16.04 ?

[stefaanv]

Hi, I'm trying to activate a sensebender gateway in OH2 on Ubuntu 16.04, however I'm having trouble setting up the serial port. Is there a how-to somewhere ? I suspect the serial port name is /dev/ttyACM0, but I'm not sure. How can I test ?
MySensors bundle is reported to be active, but there's no messages coming in. I set the log level for mysensors to DEBUG, but nothing on the log.

[stefaanv]

Here is my configuration file (mysensors.things)
Bridge mysensors:bridge-ser:gateway [ serialPort="/dev/ttyACM0", sendDelay=200 ]
{
humidity keuken_vochtigheid [ nodeId="3", childId="2", smartSleep=true ]
temperature keuken_temperatuur [ nodeId="3", childId="1", smartSleep=true ]
}

I suppose ttyACM0 because of
stefaan@home:~$ dmesg |grep -i tty
[ 0.000000] console [tty0] enabled
[ 22.328631] 8086228A:00: ttyS4 at MMIO 0x81420000 (irq = 39, base_baud = 2764800) is a 16550A
[ 22.329059] 8086228A:01: ttyS5 at MMIO 0x8141e000 (irq = 40, base_baud = 2764800) is a 16550A
[ 23.106128] usb 1-4: FTDI USB Serial Device converter now attached to ttyUSB0
[362074.592743] cdc_acm 1-3:1.0: ttyACM0: USB ACM device

There seems to be a premissions problem om the port :
stefaan@home:~$ cat /dev/ttyACM0
cat: /dev/ttyACM0: Permission denied

doing 'sudo usermod -a -G dialout openhab' doesn't help

Anyone any ideas ?

[stefaanv]

ttyUSB0 is a (different) RFXcom device

[zboblamont]

@stefaanv I can only suggest scanning the ports. When I connected the Gateway to the Pi3 it came up with /dev/ttyS0 instead of the listed options, although I ultimately ended up changing to a Pro-Mini as the radio did not work, and connected direct to the GPIO the serial port it worked with.

[tbowmo]

it should pop up as ttyACM0 or ttyACM1 (if you have another usb device that enumerates first and gets ttyACM0)

I added the following to /etc/udev/rules.d/10-local.rules file:

ACTION=="add", ATTRS{idVendor}=="1209", ATTRS{idProduct}=="6949", SYMLINK+="ttyNRF24"

What that does is to create a symlink from the real device to ttyNRF24, so regardless of what I add to my rPI, i always know that ttyNRF24 is for my gateway.

(and then I use /dev/ttyNRF24 for the serial port in my controller)

[stefaanv]

@tbowmo Definately ttyACM0
However, the setserial command returns information that doesn't look good : port0 and IRQ0. Does the board need a driver under Linux ?

stefaan@home:~$ sudo setserial /dev/ttyACM0
/dev/ttyACM0, UART: unknown, Port: 0x0000, IRQ: 0, Flags: low_latency```

[tbowmo]

@stefaanv

No, it doesn't need a driver..

I get the same for mine, if I use setserial:

thomas at jarvis in ~ 
>sudo setserial /dev/ttyNRF24 
/dev/ttyNRF24, UART: unknown, Port: 0x0000, IRQ: 0, Flags: low_latency
thomas at jarvis in ~ 
>ll /dev/ttyNRF24 
lrwxrwxrwx 1 root root 7 nov 11 13:39 /dev/ttyNRF24 -> ttyACM1

Btw. the permission problem.. You are logged in using your normal user (stefaan) and then you set permissions for openhab user? (see below). Have you tried setting the permissions for your user, and then cat /dev/ttyACM0?
