Hi guys.
big problems here, I'm not able at all to let the system work
System is based on raspberry pi and emontx v3
emontx v3 connected with 9VAC transformes, red led blinks
on rpi side, I flashed the sd card as described here http://emoncms.org/site/docs/raspberrypigateway
I switch rpi on, kill the process for debug purposes and started by hand.
here the result of
python /root/oem_gateway/oemgateway.py --config-file /boot/oemgateway.conf

and stops!
I have some questions:
1st. on RF12 module, the green led should be on or off? in my case it switches on for few seconds during boot, after it is off
2nd question. What are the sgroup and the nodeid I have to use?
3rd question. How can i change them from ssh? every time I try it answers that filesystem is in readonly mode, even after ipe-rw
Thanks for your support. I don't really know what to do
Re: Issues!
Good work it sounds like your nearly there.
As is mentioned in the emonTx V3 documentation the pre loaded firmware is shipped on network group 210 with frequency to match what you ordered. You need to set the rfm12pi to be on the same network group and frequency to match the emonTx . I see that your rfm12pi seems to be on group 1.
The easiest way to edit the network group and frequency of the rfm12pi when using the raspberry pi gateway is to insert the sd card into a computer and edit the oem gateway. Conf file using a text editor.
Re: Issues!
Yes I red it, and I tried, but some result...
Other ideas?
Is the problem on the raspberry or on the emontx side?
Could some bad weldings cause this issue?
Is there any way to be sure emontx sends the data?
Re: Issues!
Have you got a USB to UART cable? Can you see the serial output from the emonTx at bootup? It's at 9600 baud
Re: Issues!
Yes, I bought the adapter too, I will try during lunch.
What should I see? Is there some troubleshooting guide that could be helpful for me?
Thanks
Re: Issues!
hi again.
I don't see anything.....
9600 8bit 1 stop no parity. Right?
Re: Issues!
Done!
emontx was not programmed.......
it was hard but now seems ok
Thanks
