Serial Gateway Failure

[clippermiami]

@hek I haven't had time to try the old Nano in anything else. But BOTH Nanos show the Green LED periodically when the sensors transmit so they are apparently good and working on the "other than USB" side :)

The strange thing was i fiddled with it a number of times and then Bingo, the Serial Port stuff appeared. It worked, I was able to reacquire the sensors and everything looked fine. The I powered it off/on to move and and when it came back up nothing.

Don't you just love how unpredictable Vera is... ;)

[clippermiami]

@hek Well actually "Love" isn't QUITE the word I would use :)

I love my mother-in-law, yet at moments I want to choke her out.

Vera's are a lot like mother-in-laws, yeah?

[clippermiami]

@BulldogLowell That's on a good day :)

I just don't know where to go from here. i'm reasonablely confident in the Gateway itself. I don't see how it can be the Nano, its a new unit and it looks like its receiving date from sensors. Its a new unit so the probability of a USB side problem is slim.

I've reloaded all the Arduino files but i'm tempted to a) remove the gateway, b) delete the files from Vera c) reload Vera files d) reconfigure.

Any thoughts?

You might need to ssh into your Vera to see what is happening (or not) when the USB is plugged in. I have seen a thread about how get Vera to recognize odd FTDI versions somewhere but can't seem to find it now.

[clippermiami]

@hek Good idea, I might try that if I can figure out where to look :)

Further to the saga of the Serial Gateway failure, I have discovered that Vera/Arduino are a lot like Windows Plug-n-Play: You Plug it in and Play with it for a while and eventually it will work +)

This morning I unplugged the gateway and plugged it into my laptop, started the Serial Monitor and got screens of data as sensors sent data to the Gateway. So, now I know for certain that the Gateway is working the USB is working, the cable is working... EVERYTHING is working but it isn't :)

So I plug it back in the Vera and try to select the Serial Port; No Joy. I hit the Reload on Vera, click Develop Apps, Serial Port and VOILA, all of a sudden there is the configuration data for the port. Configure the port, Vera restarts and my sensor network runs again.

Plug-n-Play. Once you understand this concept all is revealed to you :)

I think its time to start working on the Ethernet Gateway

@clippermiami Your experiences are very similar to mine (although I do not have any sensors yet). My USB gateway sometimes refuses to be identified by the Vera. But I have noticed the LED behavior on the gateway and have seen that sometimes, it does not seem to boot properly. I suspect the power supply from the Vera USB port is totally sucky, so I have ordered a ethernet module and will probably go for that approach instead :)
Btw, do you (or anybody else) know if it is supported to use DHCP for the ethernet GW? I intend only to use it for IP assignment. My router will map the GW MAC address to a static IP of my choice.

@clippermiami
Ha ha. sometimes you have to make a very special dance backward around Vera singing loudly while sacrificing a small arduino or similar to the Vera gods to get things working.

@Anticimex
Yes, but it will suck a lot of extra valuable flash. I disabled all DHCP in library to make it fit at all. 1.4 uses a few bytes less so you might squeeze it in now.

@hek Ah, I see. Well, for a GW, I suppose that once you got it working, there is no need to add extra features and sensors to it (I do not intend to anyway) but it is not a deal-breaker, just a convenience. I will start off on the 1.3 release just to get the stuff running, and then upgrade.

@hek Ah yes, The Sacrifice of the Vera Virgins ... I think my problem was that I didn't wait until the Full Moon or something :-)
