Help a beginner

Hi
Please can someone help me getting started with Base and Room nodes. I tried following the wiki but it made reference to RF12demo, RFDdemo and HAHcentral, totally confusing. Derek kindly updated it to make it clearer.
However....when I type
# /etc/init.d/xap stop serial
# microcom -s 57600 /dev/ttyUSB0
and a couple of returns there is no response.
If I repeat the command I get about 100 lines of data starting with
Available commands:
<ard node ids are 1..26)
ase 'A'..'Z' to set id)
<n433, 8 = 868, 9 = 915)
<nnnM12 only allows 212, 0 = any)mode (advanced, normally 0)
ize test packet, with ack
.to node <nn>, with ack
...,node <nn>, no ack
seems to be corrupted.
I can hook the node up to my laptop and run "Putty" and configure the freq and node?
On HAH when I try to reflash the node I get
# stty -F /dev/ttyUSB0 hupcl
# avrdude -v -c arduino -p m328p -P /dev/ttyUSB0 -b 57600 -Uflash:w:HAHcentral_n

Don't know where to go from here.

Flashing
Hi John,
First check that you don't have any other services running that might be using the USB ports, just disable them through the web GUI before starting, you're right, the output does look corrupted. Once flashed, you can hook-up the node to your laptop to configure it using putty, you'll need to know the serial port that your USB has been assigned though.
I think the reason for the corruption is why there is now the "nocfg" version, when the HAH boots with the normal code, it seems to send characters down the USB port to the node, it has been known to reconfigure the node without you wanting/realising it. The nocfg version disable the configuration section.
So the steps to flash a node put simply should be :-
1. Flash HAHcentral
2. Configure node id and MHz band, remember each node should have a unique id but the MHz band should be 868 on them all
3. Flash HAHcentral_nocfg for the base node OR roomnode2 for a room node
I'm not sure if any of this helps, I can probably find time to test here if you get really stuck. See howq you get on, these are great devices, taking the HAH to a completely new level.

CaSe Sensetive + typo
John,
I assume you curl'd your hex files from google - perhaps using the example commands from the wiki?
If so, check your filenames you downloaded for spellings you may not expect, and CaSe SenSetIvitY.
Here is a quick ls of my dev box:
# ls
HAHCentrol_nocfg.hex IRNode.hex roomnode2.hex
HAHcentral.hex rf12demo.hex
#
notice the spelling AND CaSe of the nocfg file....
.... I think the wiki has been updated, but do check the avrdude commandline corresponds with the hex files downloaded.

ps: If you have a USB-BUB from jeelabs/modern devices, you can just download the PDE files from google and upload via IDE v1.0 (have not tried new 1.01). Choose the UNO for jeenodes and Duemilanove w/ATMega 328 for hahnodes.
I find the PL2303 cable (from shop) works flawlessly on HAH, but not on my laptop's USB hardware (except just for serial comms) :(
(I have not tried to work out why, no time!)
I am actually in process of doing this myself, just got all my nodes running yesterday, so I could probably help some more if needed.
3xJ's 2xH's, 1xCentral. I mounted 2 hah's in airwick, other in custom enclosures (will provide notes shortly).
If you ordered HAHnodes, you may have rec'd only 3 plugs, 2x3pin+1x2pin, I think in that case you desolder one of the airwick plugs (i used red) and solder onto the hahnode battery terminals. This is in the wiki, but on a different page to that which I was following. However, as you are flashing now, I assume you did this already.

Hope this is of some help.
as i have a full programmer BUT do you have a current cost connected as well there is a small issue on reboots they sometimes swap usb0/1
if you do try doing it with just jeenode.

not much help i expect :(
