Laird RG191 working in Australia

Hey all,

I was just looking at the RG191 and wondering if there was any update. The units look good for a few different purposes… especially with the price and BLE inside.

Is there anything else someone would recommend (must include Eth, Wifi, BLE) to use instead?

…Skeeve

I hoped to buy a few hassle-free gateways to deploy in Perth. After a lot of wasted time invested in Raspberry Pi RAK 831 shield gateways I decided to move to a more ‘commercial’ option.
I contacted Laird to ask what their position was in support for AU915 frequency bands at the moment and got this response:

Currently (as of Mar 2018), RG1xx supports three packet forwarders : Semtech, TTN, and Loriot packet forwarder.

The regional support that we include in our firmware affects the Semtech forwarder only. This region parameter is used to draw the radio frequency graph, including any restricted bands for that region, and limits the user from selecting a band that’s not allowed.

However if the you opt to use one of our trusted third parties, such as the things network using TTN packet forwarder, you can select the region of operation from the servers. This effectively bypasses our internal checking and relies on the third party for compliance to the regions restrictions

Has anyone taken this approach with the RG191 in Australia? I am unclear how I can alter the packet forwarder given the restrictions discussed previously in this thread.

The latest firmware includes the (no longer maintained) TTN packet forwarder. In the user interface you can choose to use this software in stead of the Semtech forwarder. Once you select the TTN software the ‘issue’ disappears as it downloads the frequency plan from TTN and does not use the locally configured frequency plan.

Choosing the packet forwarder does not involve any region checks :wink:

Just to clarify @kersing

The previous threads discussed the difficulties in configuring the gateway without root access. Are you indicating this is no longer essential to adjust regional frequencies in the packet forwarder?

For the TTN packet forwarder this is nog required because that file is not used. The TTN forwarder downloads the required configuration from the back-end.

@jmarcelino or @DPI-OAI can you have a go at this when you get the chance - I would like this cheaper alternative as well working in Australia

cheers

@Paul_Stewart it might be hard to imagine, however I do own a RG186 and configured it for TTN with the TTN forwarder, so I have tested the mechanism and can confirm Lairds statement.

@kersing Is there any gateway out there you don’t own or know inside out? :slight_smile:

Thanks for the notice of an update.

It seems to be working now. I updated the firmware, configured the gateway as per the TTN settings, and I have data flowing from a sensor. I’ll keep testing, but so far so good.

Some more details …
Firmware: Laird Linux gatwick-laird-93.7.2.9
LoRa settings:

  • ignore presets
  • forwarder = TTN Forwarder, gateway id as per TTN

The status then says:

  • Gateway Connected = true
  • Gateway ID =
  • Region Code = US
  • mode = ttn

Seems to be working on AU915 frequencies. I haven’t tried AS923 configs.

A couple of additional things that may help those struggling to set up a RG191:

-You must update the firmware. If you are struggling to update the firmware, do a factory reset. I had to perform 3 factory resets before the firmware updates worked as per the user manual.
-as @DPI-OAI indicates you need the gateway id as per TTN, you also need to include the gateway key as per TTN

Great to finally have a choice of cheaper gateways in Australia!

I can confirm Laird RG191 runs for AU915 region.
Using the latest version.
The “Radios” graphical interface is limited to 903-915MHz, don’t use it.
Save current LoRa configuration in a json file.
Edit the json file, change this:

"radio_0": {
"freq": 917200000
},
"radio_1": {
"freq": 917900000
},

Upload a saved LoRa configuration json filList iteme and restore it.

Hi everyone been getting very interested in their affordable pricing Gateway but well I try searching people’s expected range and testing results and unfortunately I can’t find one.

Anyone with this kind gateway by Laird would help us all by sharing your reach of LoRa Range test or will be great if you have a comparison to another gateway. Will be nice if we could also show the SNR, RSSI, SF, Frequency

Much thanks. Great day !

Can confirm @Phil_Wilko 's comments about firmware update and factory default setting. All that said, a new Laird gateway was installed and activated at a Temecula (California) winery today.

@manoj15 To my experience there is not much difference between gateways wrt range. I have tried MultiTech, TTN, Laird, and Gemtek. All have approx. the same range and signal strengths when using an identical antenna and location. Influencers are: height/line-of-sight, outside or inside antenna (estim 10dB difference), and lastly antenna gain.

@Vinduino, Reinier your photo has just the IP67 compliant case I am after! Is that the official Laird one? Unfortunately I bought mine through Mouser and they didn’t stock the Laird case. Your antenna looks somewhat better that the original one!! What range do you see across your wineries?

Also thanks for a great talk at TheThingsConference in Amsterdam earlier this year. I have been inspired to develop some things for wineries down here in Western Australia.

@Phil_Wilko Phil, this is a standard box purchased on Amazon. Link: http://a.co/0AjbGWa
Altelix 14x11x5 Pole Mount Polycarbonate + ABS Weatherproof NEMA Box Outdoor Equipment Enclosure. The two copper mounting strips are not part of the standard enclosure.

@Vinduino do you have any figures on the power draw of the RG191?

I’m looking to roll out some gateways at solar powered sites so every watt is critical if you want to ensure 24/7 unattended operation.

As an example, one of my existing sites has 660w of solar panels and 12.5kWh of battery capacity to support a 26 watt continuous load. You can imagine the scale of changes required to reliably support 5 watts of extra load.

@jbkiwi Interesting project. Please keep the forum updated on your solar powered gateway.
Have not measured RG191 power draw. The std wall adapter is 12V 2A. I have used PoE adapters rated 12V 1A with RG191 without issue.

@jbkiwi @Vinduino Like you I am looking at some ‘off-grid’ sites where I will have solar back-up and also at some sites running on passive/low voltage (vs 24/48V) POE enabled GW’s - I’m running RG186’s in UK/EMEA so hopefully not too much difference with your 191’s.

When I checked with the dev team at Laird I was advised 12v quickly dropped on motherboard and therefore should be good for 6V to 18V range at adapter input , later amended down to 15Vmax due to presence of a fuse on board (should help with limiting regulation and supply losses from solar panel and associated back-up battery). No ‘guarantees’ but if supply not too noisy potential for operation down to <=5V - 4.5V poss but YMMV.

As a test I have run a couple of sample gateways (in benign environments not testing over temp/in the field) from a 5V supply and also from 5V USB power-bank with no issues over many hours…GW was not heavily loaded and was only handling packets from 5 or 6 nodes - so again overall performance may vary if handling 100’s/1000’s of nodes,generating high load and lots of network traffic :wink:

Using a simple USB power monitor I was able to test rough order of average current consumption - wasn’t monitoring peaks - and typically saw operation at around 350-400mA…see sample pic attached :slight_smile:

During GW startup measured voltage was 5.01 - 5.06V. Actual voltage measured during steady state op was ~4.97V not the 4.94V indicated on display!

Good luck…keep us posted on what you see. I will be running more tests later next month with 4 or 5 new GW’s and will update here also…
