(Lachlan Etherton) #423

Unfortunately, I can’t see the mention of AU915 in the description of any links for where you can purchase the gateway. For someone in Australia, what one should I order? Would US915 work after a firmware update?


(bluesensing) #424

read this, pls.:

order it in germany: https://de.rs-online.com/web/p/entwicklungskits-hf/1843981/


(Lachlan Etherton) #425

I’ve had a read it. It does mention Australia, however on the pages where you can order the gateway, it refers to AS923. This is an Australian supported frequency, but not AU915, which is different.


(Wsaiho) #426

In Singapore we can use the EU868 band also, but RS-online link for the EU module doesn’t seem to ship here


(Jac Kersing) #430

There will be resellers. It was the same for the first TTN Gateway after the Kickstarter, only available at RS and Farnell, now there are resellers offering it.


(Jac Kersing) #432

Yes of course. Resellers need to handle warranty, customer complains, returns etc due to (European) law. Don’t expect them to do that without some financial compensation.

BTW, I was looking into setting up something like a group buy offering consumers the option to buy. Given the negative feedback I’m dropping that idea as I don’t want to handle the fallout if things don’t meet everyone’s expectations…


(Ud Lo Ra) #436

In Italy is available. I ordered one as private customer (so maybe it’s not TTI but German RS the problem).


(Remko) #438

Same here in The Netherlands


(bluesensing) #439

You got it as a single private person ?


(Jac Kersing) #443

I like the truth as well. And I told you my opinion straight.

For me you are ranting. I understand your frustration but like I said, contact the responsible people.
WE (the other members of this community) can not change what is bothering you.

Having said this, I would suggest one of the other moderators looks into this and starts deleting/moving as appropriate because we are way off topic with this discussion in this thread. A new thread on this topic would be more appropriate.


(Ud Lo Ra) #448

Yes, as a single private customer. Anyway, I would be more convinced of your point if you are able to provide some EU equivalent of the German “privat” site. I expect is just a matter of national tax rules.

Can some TTIG owner here please check the precision of it’s time?
I recognized that the timestamps sent by my TTIG are around 800-900ms stale.
See server log below. The first gateway in the list is a MatchX1701, outdoor with gps.

 "gateways": [
    {
      "gtw_id": "eui-40d63xxxxxxxxxx",
      "timestamp": 2739507028,
      "time": "2019-03-18T21:10:03.576662Z",

Alle off the gateways looks here the same:

  > "gateways": [
"gtw_id": "ttn-Multitech",
       "gtw_trusted": true,
       "timestamp": 1772843603,

"gtw_id": "ttn-Gateway",
      "gtw_trusted": true,
      "timestamp": 3556385187,
      "time": "2019-03-19T07:45:52Z",

"gtw_id": "eui-58a0cb-TTIG",

      "time": "2019-03-19T07:45:52.679976Z",
      "channel": 0,

At some ms the same

Great, that’s exactly what i would expect.
But things are different here, question is why.
Since alle TTIGs do not have GPS and are uplinked via Wifi, the chain to get time from external time source should be always the same, so i assume this can’t make any difference.

What TTIG version do you use, EU or US?


#452

Hello Verkehrsrot,

I use the EU version (based arround Amsterdam)


(Arjan) #453

Are you seeing the difference all the time, or is it better every now and then? When attaching the UART, you might see things like:

[SYN:INFO] Time sync qualities: min=108 q90=184 max=665 (previous q90=2147483647)
[SYN:VERB] Time sync rejected: quality=244 threshold=184

The same Basic Station documentation also states:

  • No Dependency on Local Time Keeping: Station obtains time synchronization from the LNS with no need for a local UTC-based clock. …
  • No Incoming Connections Configuration: … Time synchronization and shell access are managed via the LNS with no NTP or ssh required.

Finally, the LoRaWAN Network Server Protocol defines:

Transferring GPS Time
The LNS SHALL periodically send the following message to Station to transfer GPS time.

Now, define “periodically”…?

Just spoke to RS UK and they are now saying expected 29/3 - this has slipped a week.


(Jeff Uk) #455

:frowning: Mine were due to ship today! …no comms from them


(Jezd) #456

Mine too, that’s why I called - also my order morphed into the following…

Hostaform Bevel Gear 30 Tooth 2 Mod 3:1
Stock no.: 1843981

I’ve no idea what they are doing
