(Arjan) #339

Nice!

Maybe those are only EU868? I also see 178 EUIs starting with eui-00001c497b.

Many of those are registered for EU868 as well, but maybe they’re really US915 devices configured for EU868 in TTN Console. (I don’t know how many people got the US915 device when the EU868 was no longer available at the conference.) The EUI surely determines the frequency plan/configuration, so multiple ranges might be expected:

…though it seems the above might only apply to receiving uplinks, as settings in TTN Console affect the frequency for Join Accept downlinks. At least those that are displayed in TTN Console, for a US915 device configured for EU868:

Is there a way to switch network servers? i.e. register this GW on the IoT-in-a-Box network? I imagine you have to unregister from the TTN network first… or?


(bluesensing) #341

today i determined a radius of 623 meter for TIG (EU Version) in Berlin , indoor, 1st floor. very good, very happy. measurements goin on… very satisfying…


(Ibelinp) #342

A few more pics. image image


(Verkehrsrot) #343

Looks like this is a part of this one:

(Verkehrsrot) #344

“LBT” = Listen-before-talk?


(Ibelinp) #345

The module in the FCC documents looks different. Here is the actual concentrator “under the hood” . There is an ICE40 FPGA in the TX path of radio A. image image


(Jeff Uk) #346

Probably yes…note the additional SX1276 - probably used for the ‘Listen’ :wink:

tiginit

wow… smooth install :open_mouth: in 5 minutes

it just… works

tiginit2


(Verkehrsrot) #348

Discovered today: If the TIG is powered by USB-C and not by 230V wallplug, it keeps cool.


#349

it doesn’t need the AC-DC part…


(Verkehrsrot) #350

Yes, of course, but let’s assume that the AC/DC part is not working very efficient


#351

I have it plugged in for half an hour… it’s not 'hot , the adapter from my internet modem and televison decoder are really hot :sunglasses:


(Verkehrsrot) #352

I did a small survey on energy consumption of the TIG:

  • powered by 230V, using TIG’s wallplug: 2,9 - 3,0 Watt
  • powered by 230V, using USB-C from a 5V/3A power supply: 2,3 - 2,4 Watt

Looks like the built-in power supply heats at least 25% of the drawn energy, this is not “green technology” :frowning:

…but, okay, it’s less than 2€ cost per year :slight_smile:


(bluesensing) #353

opening encasing will void guarantee, i suppose… and it’s dangerous


(Verkehrsrot) #354

:scream:


(Ud Lo Ra) #355

No one here is used to do that, we are prudent and respectful :grin:


(Lag Compensator) #356

Hi.

Maybe this have been addressed already, but I was not able to find anything.
Problem:
I have multiple gateways picking up my messages, however when I look at the metadata and see the different gateways recieveing my message I see the following:

On my mini gateway (handed out at the conference) the channel always display 0, while the other gateways that picked up the message shows the “correct” channel, see attached image.
Also, I’ve seen the minigateway show SNR of +15, while the lorix1 showed -12 (highly unlikely).

the “another lorix1” is approximately at the same distance as my minigateway to this perticular node shown in image below, both of the lorix gateways are mounted outdoors ~5-10m above ground.

Gateway settings (same for all gateways):
Europe 868 MHz
ttn-router-eu

metadata

Thanks.

compareports
I’ll try to replicate that … :sunglasses:

  • true… I increased the RF power and now one more gateway answered on port 0, that must be a TIG too :wink:
    conclusion: metadata is wrong you’ve found a bug
