Things Indoor Gateway - TTIG part 1

I receive two units this week, USA 915MHz…

Was un-able to get them to connect to my hidden SSID WiFi network, had to build an open SSID network.

  • When will we get new firmware update for these devices?
  • Will the code base be available on GitHub?
  • Is there a place to publish issue as they relate to the TTIG?

thanks

Lucky you! Unfortunately I’ve still got problem with RS Components.
Please help me, where I can buy one?

Is there any chance the TTIG aggressive disconnect/reconnect logic could be relaxed a little?

I have a single TTIG that I use for testing various end nodes. One node in particular reports once an hour. It’s the only Lora device around and there are no other gateways in reach. The problem is that if the TTIG is in the middle of reconnecting, it seems to drop or not hear the node. This happens quite frequently.

I guess I could do some sort of keep alive node, but that seems a bit of a kludge.

Ours does not seem to set its clock via NTP?

Any ideas how to configure this?

Seen that today. Its a real pain! Will miss packets

That’s not the gateway sync timestamp. That’s the timestamp in the network metadata. I’ll fix that in the next update.

Yeah well we could try to increase the disconnect time. But this still means that if your nodes send data while it reconnects, you will still miss packets.

Same here. Before the timestamp disappeared, time was around 800ms stale.

“gateways”: [
{
“gtw_id”: “eui-58a0cbfffexxxxxx”,
“timestamp”: 1003390635,
“time”: “1970-01-01T00:00:01.565950394Z”,
“channel”: 0,
“rssi”: -67,
“snr”: 6.75
},

Good point. Lorawan wasn’t really designed for 100% packet delivery applications.

I received yesterday some 868 MHz TTIG (gateways) from RS . The right (EU) power connector was included in the box. The Things Network registration was very succesfull (5 min) on the first attempt.
The location’s are now Netherlands (Uithoorn), but they will be placed somewhere in Friesland (north off the Netherlands) for a monitoring project.
These gateways will be converted to a external antenna as I did above.

Great news it looks like they are finally offering a version of the TTIG with a UK mains power shoe:

BAD NEWS: Looks like we are to be ripped off for another £15!!!

I recently bought a branded 8 port 10/100 desk top ethernet switch from Amazon - which came with power adaptor shoes for EU, UK, US & (I think AU or similar) for less than half the cost of this uplift. & thats including VAT! (Edit - and free delivery! :slight_smile: )

@wienkegiezeman are they serious?!

Hi all I had the issue that RS supplied an EU shoe for my TTIGs I ordered.I then pointed out that products sold in the UK have to have a UK plug fitted. I was sent several in the post free.

I have this gateway since 2 month and screw an external sma connector on it. I think it’s quite good but I prefer to mount it outdoors to shorten the antenna cable length and mount it at a high point.
Is the electronics inside basically able to withstand temperatures down to -20C up to 50C? A water protected case should not be a problem including condensate water outlet.

In principle, SX1308 has a reduced temperature range (0-70), so not suitable for outdoors.

Specs wise probably not, but depending on the external case used, when using TTIG’s built-in power supply it will at least be a bit warmer than the surrounding air temperature.

I was thinking the same but this should be a good isolated (Polystyrene foam) case that does not overheat in summer.
The receiver is quite good, maybe it’s worth. On the other hand 3-5m antenna cable is much easier to realise…

I was going to suggest the same, but thinking at the other side of the range, it might become too hot under the sun… and not sure that with continuous exposure some foam will suffice . With a more programmable gateway, I would add a temperature sensor in the enclosure to monitor the situation.

Yes. Unfortunately the TTIG is not that programmable.
Its ESP8266 MCU is limited on resources and available IO ports. An ESP32 would have been more flexible and more powerful.
