Pygate - ethernet reliability issues
-
I've changed the LoPy4 for a WiPy3, still using POE Ethernet for backhaul to The Things Network. It barely lasts overnight.
-
@thinginnovations said in Pygate - ethernet reliability issues:
@peterp Pygate is the lora gateway!
Sure. I was trying to suggest steps to narrow down the problem.
I.e., establish an eth connection and use it continuously for some up/downloads, but do NOT use the gateway functionality. Is the connection stable? If yes, then the counter test could be gateway over WiFi.
-
Hi,
ok. I can confirm that the PyGate with WiPy3 stops responding to PING requests a few minutes after startup with PoE.
But I can't confirm that the PyGate didn't work anymore. The Gateways status within the TTN Console is updated every 30 Seconds or so for the last 15 days.Hope this helps

@schmelpe given the timeframes announced by several people (hours or days) I was wondering if maybe there was a link with DHCP lease times or something similar. But if you see issues after a few minutes, unless your DHCP leases are extremely short, that’s probably not the culprit.
Is the “stops pinging after a few minutes” repeatable? Is it always the same time/number of pings? Are you pinging from a box on the same network or a different one?
-
@jcaron I found an interesting thing.....
DHCP Lease is set to 8 hours on my router.

During my tests yesterday, my Pygate stops answering to a PING after 1 or 2 minutes after powering up the device (remember, it runs 15 days or so 24/7 and was really hot). Yesterday afternoon I disconnected the Pygate because one of my Sensors didn't Join via OTAA (a known PyGate problem).
-
This morning I powerded up the PyGate again (ca. 29°C room temperature) and the PyGate always answers to a PING.

But, the connection to TTN is working and refreshes every 30 seconds. Only PING is no longer working.
Don't know how to figure out the problem.Hope this helps

@peterp Using a pygate lora gateway. Attached is a photo of ping results from local network using dhcp and POE+ ethernet. Happens every time. Disabled lora gateway and trying with WIFI (powered via POE) to narrow it down. Will follow up.
-
Hi,
I believe the issue is not heat related (I just tested the Pygate (with the lora concentrator disabled)) and PyEthernet. Applied heat with a heatgun and checked the ping times. I was not able to find any differences, with heat applied of about 100*C.Now I did some further testing, and sometimes pings are not getting through with the Gateway enabled or disabled. I cannot seem to reproduce the case of @tronto Where the ping times significantly increase after a few timeouts.
Pings are generally <10ms on our network, with few going above that..
Also, I see no relation in the lost pings compared to the Pygate dropping any lora packets, but please do let us know of your findings!
Btw @schmelpe, you mention OTAA not joining being a known Pygate problem, could you elaborate? I believe the issue you are referring to has to do with frequency plan settings not being in sync..
Best,
Gijs -
@Gijs My issue seems to be related to ethernet communication. I don't seem to have the same issue using wifi for communication (and power from POE). Have tried two different brands of switch (ubnt + cisco) with same results with eventual ethernet drop out.
I believe both switches saw the POE module as 10FDX if that makes any difference.

Hi @Gijs ,
no, I don't think so.
Please look at this Thread: https://forum.pycom.io/topic/6206/cannot-make-join-otaa-timely-with-pygate-and-lopy4.
I'm using a WiPy3 with firmware 1.20.2rc10 and have exact the same problem.
OTAA JOIN request over Pygate do not work for me (EU868), OTAA JOIN requests with my other TTN Gateway are working fine within two or three attempts.
You'll find my code in the this thread.

There is no new firmware for the PyGate available. 1.20.2rc10 seems to be the last one.Best regards

@tronto The PyEthernet has a 10/100 Mbps ethernet (in 10 mode) controller that talks over an SPI bus at 8MHz. In that datalink, it is probable some incoming packets will get dropped. Ive had mine run over the weekend and it is still connected to TTN (on a netgear gigabit switch). I have heard of the possibility that using a 10 Mbps device on a switch could drop all the traffic through the switch to 10 Mbps (I have yet to see a reproduction with the PyEthernet though). Another issue can be related to the single jumper on the PyEthernet (close to the Ethernet port). Some (older) PoE adapters require a minimum amount of current to be drawn or they will switch off. The Pygate is generallly below the minimum, causing the PoE to dropout for a second, inserting the jumper will connect a default resistor load.
@schmelpe, I looked into the OTAA issue myself as well, and could only reproduce it (as the original problem states) by bodging of frequency settings.. Moreover, the OTAA join accept is still send out when the logs mention 'Ignored not rejected'. If you are experiencing LoRa OTAA issues at EU868MHz, with the frequency settings set correctly on all devices, please do let us know! (nb. Ill take up the firmware versioning with the firmware team, seems they missed to upload it!)
I am currently working on testing different frequency settings using the configuration files from here: https://github.com/TheThingsNetwork/gateway-conf and adding
"gateway_ID": "XXXX", "keepalive_interval": 10, "stat_interval": 30, "push_timeout_ms": 100, "forward_crc_valid": true, "forward_crc_error": false, "forward_crc_disabled": falseat the bottom of the config file, within the closing brackets. Let me know if that works better for you! (ill add it to the other thread as well)

Sorry for the confusion!
The configuration files are very similar in the end, but I feel like the configuration provided by TTN is slightly better than the one we created ourselves, but let me know of your experiences! They also have examples for more regions than we do currently ;)Best,
Gijs -
@Gijs: Ok, understood. I'll update my PyGate in a few minutes and see the what's going on. :-)
Thanks, Peter

Hi @gijs,
Please excuse the late response, but I wanted to make sure everything works now.
As you recommended, I used the config.json for EU868 from the TTN for my PyGate. So it seems to work perfectly so far. The devices I tested need about 5-10 seconds to join the TTN via OTAA.
Thank you very much for your support.Best wishes

Hi @Gijs,
I have now also found the solution for the Ethernet reliability problem.
It's because of the WiFi that I use to ping. I suspect the Ubiquiti Nano HD AccessPoint as the cause. If I send a ping via Ethernet, this is always answered 100% by the PyGate. Even after several days of continuous operation. At first I was not aware of the problem with the access point, because the ping losses occurred from several computers, all of which were connected via WLAN. Only after I ran the ping tests from a stationary computer did I no longer have any problems.
So sorry for the noises ...Best wishes
Peter -
Good to hear the issue got solved!
I believe there are still people out there that do have problems with the PyEthernet dropping the connection, so thanks for your take on the situation!
Also good to hear the TTN configuration works better for you. I will work on putting this in the docs!
Thanks

@Gijs Dear Pycom,
I have got a new Pygate, Wipy & POE module connected and fully updated to the latest (stable) firmware as of this evening.
I am using a 5V 2.5A USB power supply connected to the USB-C port of the PyGate.
There is an ethernet connection to a 1Gbps switch on my desk which works perfectly fine with other devices.
I am having this code in my device:[jaap@jaap ~ ]$ curl ftp://micro:python@10.0.0.99/flash/boot.py # boot.py -- run on boot-up from network import ETH e = ETH() e.ifconfig(config=('10.0.0.99', '255.255.0.0', '10.0.0.1', '10.0.0.1'))[jaap@jaap ~ ]$ curl ftp://micro:python@10.0.0.99/flash/main.py # main.py -- put your code here!No more. No gateway yet.
Now I am seeing this erratic behaviour:

@Jaap-Crezee Have you tried setting
wifi_on_boot(false)? Though this could possibly explain the initial packet loss, but probably not the 8 second latency and later packet loss!Also I believe Pygate builds don't include Pybytes, but if they do,
pybytes_on_boot(false)would be a good idea.It would probably be interesting to run a simple UDP client+server to check in which direction the packet loss/latency occurs.
Is the Ethernet switch managed? Do you see any errors or link bounces on that?

@Jaap-Crezee We are (sort of) aware of this issue and we can reproduce it, but we have not been able to ' trigger' slow ping times on demand. My colleague @peterp looked into this for a long time, but we could not pinpoint the cause of it. In our case, it takes hours or even days before it gets into this state when pinging the device. It seems yours gets in this state of slow ping responses relatively quickly. Now the only difference between your setup and ours, is in the network infrastructure (I believe), making me believe the issue can be found there.
The suggestions of @jcaron sound like a good place to start (I think we evaluated that as well, but I dont remember the outcome exactly). We tried a whole assortment of solutions but none have resulted in a proper triggered reproduction.
Note that we are not able to reproduce it when using the product as it was meant to be (A LoRa gateway connected through wired internet / PoE), only when we are throwing pings at it.
Let me know if you have any suggestions!

Thank you for your inputs. I will try the two disable commands. Could it also be related to receiving a lot of UDP broadcast messages?
I am on a noisy network. I could also try moving to a less noisy network (although I would argue that a device should not get slower by receiving some broadcasts; we are talking about 0.5-1kbyte/s here.). And we are not always in control of the networks we should be connecting to.
I will get back once I have some results.
