Adding commands for LV5048. #11

Closed DMIINC closed 4 years ago

DMIINC commented 4 years ago

LV5048 5KW protocol-20190222 for customer.pdf Hello,

Thank you for your help last week. I was in touch with MPP Solar and they provided communication protocol for LV5048. See attached. Is there way to integrate some of these commands with what you have written so far?

DMIINC commented 4 years ago

Do you maybe want to do it with usb only? Instead usb to serial as is it now?

jblance commented 4 years ago

start with usb-serial

DMIINC commented 4 years ago

ok

DMIINC commented 4 years ago

!st command out of watch power

1st

jblance commented 4 years ago

can you upload the pcap so i can look too I'm looking for the commands and responses

Was also interested to see if @cowpen got any actual data in response to commands that use a parallel ID

Really sorry guys. I've been up to my eyeballs in alligators trying to support 100+ work-from-home users with no company laptops. Nightmare. I haven't even had a chance to try to install the "mpp-solar" package yet.

DMIINC commented 4 years ago

@cowpen It is all good.

jblance commented 4 years ago

thanks So in the first PCAP, the commands (in order) we see are QPI at p 4684 with response (PI41 with CRC 0x13 0xbd at p 4690-4705 then

(and still only at packet 10276)

But basically, same CRC, no resends and a response to parallel commands...

jblance commented 4 years ago

@cowpen yeah no stress just interested

DMIINC commented 4 years ago

So. There is a response to QP2GSn and QPGSn?

jblance commented 4 years ago

Also @cowpen do you know how to combine packets in wireshark?

jblance commented 4 years ago

Yep command sent and valid response received Maybe wireshark capture of mpp-solar sending QPGS0 and QP2GS0 ? Coz as far as I can tell we are sending the command and getting a response, but the response is (NAK

DMIINC commented 4 years ago

Would switching to USB help to see further?

jblance commented 4 years ago

it might (it really shouldn't but at this stage it is not making sense to me)

DMIINC commented 4 years ago

OK. Giving it a try now.

DMIINC commented 4 years ago

LV5048 PCAP USB.zip

jblance commented 4 years ago

is that using watchpower or mpp-solar?

DMIINC commented 4 years ago

Watch power windows

DMIINC commented 4 years ago

Oh man I failed at reading

DMIINC commented 4 years ago

Hold on. On raspberry pi, do you want all of them connected to raspberry pi or just one inverter?

jblance commented 4 years ago

just one i think The USB one is harder to decipher too (actually I think I've figured it out)

DMIINC commented 4 years ago

Soooo, LOL How do we go about wireshark on raspberry pi

DMIINC commented 4 years ago

Use something else

jblance commented 4 years ago

Does https://discussions.flightaware.com/t/monitoring-usb-utilization-on-raspberry-pi/16421 help?

DMIINC commented 4 years ago

Checking it out

jblance commented 4 years ago

tshark looks to be the command line version Does your Pi have the GUI installed?

DMIINC commented 4 years ago

Installed.

DMIINC commented 4 years ago

Gui

DMIINC commented 4 years ago

Usp listener

DMIINC commented 4 years ago

UDP

jblance commented 4 years ago

OK - should be similar I installed tshark only and did the 'mount usbmon' as per the link and seemed to get USB capture

$ sudo tshark -i usbmon1

How did yours work out?

DMIINC commented 4 years ago

installing tshark now

jblance commented 4 years ago

with the Pi desktop installed, you could install wireshark and use the gui version for capture

DMIINC commented 4 years ago

I do have desktop installed too

DMIINC commented 4 years ago

this is what I see

Cisco remote capture: ciscodump Random packet generator: randpkt SSH remote capture: sshdump UDP Listener remote capture: udpdump

jblance commented 4 years ago

did you run

sudo mount -t debugfs none_debugs /sys/kernel/debug
sudo modprobe usbmon
sudo chmod 755 /sys/kernel/debug
sudo chmod 644 /sys/kernel/debug/usb/usbmon/*

?

DMIINC commented 4 years ago

How ever command line is working too. It is capturing my mouse movements \

jblance commented 4 years ago

lol - that will be useful...

DMIINC commented 4 years ago

I did execute what you wrote in previous post

DMIINC commented 4 years ago

pi@raspberrypi:~ $ sudo mount -t debugfs none_debugs /sys/kernel/debug mount: /sys/kernel/debug: none_debugs already mounted or mount point busy. pi@raspberrypi:~ $ sudo modprobe usbmon pi@raspberrypi:~ $ sudo chmod 755 /sys/kernel/debug pi@raspberrypi:~ $ sudo chmod 644 /sys/kernel/debug/usb/usbmon/* pi@raspberrypi:~ $

jblance commented 4 years ago

I dont have access to my pi that is connected to the inverter - but try lsusb to see if you can identify which usb to capture then try tshark -i usbmon1 (or usbmon2) in one window will running a command in another (e.g. mpp-solar -c QSID ....)

DMIINC commented 4 years ago

DMIINC commented 4 years ago

when the capture window is open what is command to make it stop capturing

jblance commented 4 years ago

control+ c tshark -i usbmon1 -w capture.pcap to write it to a file too

DMIINC commented 4 years ago

pi@raspberrypi:~ $ sudo tshark -i usbmon1 -w capture.pcap Running as user "root" and group "root". This could be dangerous. Capturing on 'usbmon1' tshark: The file to which the capture would be saved ("capture.pcap") could not be opened: Permission denied.

pi@raspberrypi:~ $

jblance commented 4 years ago

try /tmp/capture.pcap as the file

DMIINC commented 4 years ago

OK captured file with QPGS0 and QP2GS0. How do you Zip it on raspberry pi

jblance commented 4 years ago

theres a command gzip or the GUI might have compress functionality??
