Unable to use the SerialGateway code

[hari]

I've tried two different pro mini 3,3v boards, and the SerialGateway does not respond to serial commands on them. I expect 0;0;4;4; to reply the firmware version of the serial gateway. And it works fine on non-3,3V-pro-mini. The vera lua script is doing the same on startup:

-- Request version info from Arduino gateway
sendCommandWithMessageType("0;0","INTERNAL",tonumber(tInternalTypes["VERSION"][1]),"Get Version")

Trying to pick up a chat session with you. look in the lower corner of the screen (or the chat bubble at the top right of the forum).

Could this be "related" to my issue?
I can't seem to get it working with an Uno board.
I will do some more testing today.

Things seem to work with the mega 2560 after realising that it has completely different SPI pins:

pin D8-----------CE (chip enable in)
SS pin D53----------CSN (chip select in)
SCK pin D52----------SCK (SPI clock in)
MOSI pin D51----------SDI (SPI Data in)
MISO pin D50----------SDO (SPI data out)

In the sketch I use this:
Gateway gw(8, 53, INCLUSION_MODE_TIME, INCLUSION_MODE_PIN, 6, 5, 4);

Dunno why the pro mini 5V is not working, but as I'm able to talk to a sensor already I probably won't dig further into that..

@hari

Good to see you've had some progress.

I'm also trying to use a Mega as a node (not gateway) do you have any suggestions for that? I tried connecting the pins as you suggested above but it didn't work. I am still going to do some research but I thought I'd reach out to see if you (or anyone else) has already done this so I don't have to recreate the wheel.

Thanks,

Pete

@petewill My problem with the uno's is that they are not (at) all sufficiently powered on the 3.3v pin. Very odd but if I were you I would test that first Pete...

[petewill]

@marceltrapman Interesting. I'll test that tonight when I get home. Thanks!

Got it to work! Not sure exactly what the problem was because it sort of started working by accident. I think it was either a bad connection between the radio and the Mega or else it had to do with the initial start up of the Mega or radio taking too long. Not sure if that's even possible but what seemed to fix it is starting the serial monitor (in the Arduino IDE). That seemed to reset the code but not the power. As soon as I did that the messages changed from saying a "relay not found" to this:

Started sensor.

Once I got these messages I just started the Inclusion on the Vera side of things and closed/opened the serial monitor again and it found my sensors!

@hek : it happens that I have currently the same setup (3.3v mini pro as serial gw via FTDI); and am suffering from exactly the same symptoms (no reaction when I push commands to the GW). Reception, however, is ok. I plan to add a capacitor for the ripple; but given incoming reception is ok, I doubt it will make a difference?
Needless to say that uploading the sketch works fine, and that upon writing the TX led flimmers.

EDIT : nevermind, solved.
