💬 Sensebender Gateway

@MLs

have you installed the mysensors board files? And chosen the Sensebender Gateway as target platform?

(Seems that you are using Arduino/Genuino Zero as target?)

[Fabien]

@tbowmo I'm using the serial sketch.
I have few issues (I think) :

• when I want to upload a new sketch, first time after powering by computer, every led goes off and SBGW seems to be disconnected. When I unplug/plug, no led are on or blink, but detection is ok and I can upload a firmware.
• When I press RESET after connecting SBGW on my computer, all led goes off and SBGW disconnect.

And it doesn't seems to wait when I plug computer, led start blinking ...

@Fabien

Is it windows or linux? Linux (ubuntu) have a bad habit of letting modem manager snatch any ACM devices that is connected to the computer.

[MLs]

@tbowmo

Yes, I have installed MYSensors boards but find only micro

So therefore, I tried another card.

@MLs

I found the problem myself. Had just installed Micro

@tbowmo said in 💬 Sensebender Gateway:

Yes it's ubuntu ... Do you know how to avoid this ? udev ?

[Fabien]

Ok :

sudo apt-get --purge remove modemmanager

Hi i get same error whit Sensebender Ga

Arduino:1.8.0 (Windows 10), Kort:"Sensebender Gateway"

Build options changed, rebuilding all
Sketch uses 46720 bytes (17%) of program storage space. Maximum is 262144 bytes.
No device found on COM4
An error occurred while uploading the sketch
Invalid version found: 1.04
Invalid version found: 1.04

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.```

No device found on COM4
But serial monitor works fine with COM4

@MLs In Device Manager what com port is assigned to the sensebender GW? Have you manually installed the inf file?

com4 is likely the last com port you used in the arduino interface not the one assigned to the GW.

[MLs]

@Disca

No, I have not installed or selected com port.
Device Manager COM4
As I understood it so Windows 10 would fix everything, right?

@tbowmo : It's better for seeing debug from start.
But there is 2 bugs :

• When you want to upload sketch. /dev/ttyACM0 disapear (and D4 goes off) afterunplu/plug it works for uploading sketch (D4 off) but at the end of uplaod ArduinoIDE makes a soft reset and /dev/ttyACM0 disapear. Works fine after plus/unplug (D4 ON)
• When pressing reset /dev/ttyACM0 disapear (and D4 goes off). Works fine after plug/unplug

[Disca]

@MLs mmm not sure then, it works for me on Windows 7 with 1.8.1 (slightly newer version?)

[tbowmo]

@MLs

I don't have windows installed, so I'm sorry that I can't help with windows specifics.

[MLs]

@tbowmo

Now, I think it feels like hardware failure more than software errors. Will try tomorrow on my second computer with Windows 7 and see if there is any difference.

@Fabien

I added a couple of udev rules, to stop modemmanager take control over the device

ACTION!="add|change|move", GOTO="local_usb_device_blacklist_end"
SUBSYSTEM!="usb", GOTO="local_usb_device_blacklist_end"
ENV{DEVTYPE}!="usb_device",  GOTO="local_usb_device_blacklist_end"

ATTRS{idVendor}=="1209", ENV{ID_MM_DEVICE_IGNORE}="1"

LABEL="local_usb_device_blacklist_end"

Add the above to this file /etc/udev/rules.d/mysensors.rules

As the USB is native in the arm processor, then it will re-enumerate on the USB port whenever a reset condition occurs. When you press the reset button it will act as a unplug / plug operation (you can see this in dmesg)

When uploading to the gateway, it will reset itself to enter bootloader.. The bootloader will have another VID/PID combo (VID:1209, PID:6448) than during normal operation (VID:1209, PID:6449).

I have never seen the problems that you are having, where you need to fysically unplug / plug the device, after you have pressed the reset button (or uploaded a new firmware). And I have uploaded firmware (and pressed the reset button) quite some times :)

Also please note, that if you double tap the reset button, the gateway will enter bootloader mode, and wait for a new sketch to be sent.

[Fabien]

@tbowmo : Same with udev rules (but this file is not necessary because modemmanger is not installed).
I try to power SBGW with usb, D4 goes ON. After pressing reset, D4 goes OFF and never goes on (I must unplug/plu usb power). Do you have the same with your board ? Perhaps a problem with bootloader ?

[tbowmo]

@Fabien

D4 is the yellow LED, and the only place it is used is in the onboard selftest routine.

In my setup, D5 turns on when plugging in the device. If I hit reset one time, it momentarily switches off D5, and then back on. if I hit reset twice, it stays off (bootloader is activated)

The above is done on my RFM69 debug gateway, so the sketch is for RFM69, but otherwise a standard SensebenderGatewaySerial sketch

Have you checked dmesg, when plugging in, and when hitting the reset button?

Have you tried with another USB cable? Have you tried with another computer?

[Fabien]

I try with 2 different USB cable and 2 computer (1 laptop and 1 desktop). Same problem. With a charger too. And sorry for the mistake, it's D5 (orange)

Thank you @scalz !
You must have a very well calibrated printer to print it correctly. First try fails (oozing due to overtemp)
Other side tomorrow !

@Disca

Where did you find the drivers for sensebender GW for Windows 7?
