NICE!

I will take a look on it tomorrow!

Hi Svein,

could you try increasing the pause to 7000Ms to see if that fixes it as it may be that the radio is trying to transmit more often.

Can I also check which gateway you are using?

[Svein-Tore]

Hi Ryan!

I have tested with 10000ms, but got the same problem. I'm using gateway Dragino LG-01N (https://www.dragino.com/products/lora/item/143-lg01n.html).

yes it is one channel and not what I wanted. But it is almost impossible to get Pi Supplys IOT lora gateway phat today😢

Hi Svein-Tore,

Ok good news I've figured out the issue then! Bad news the workaround will take a day to implement.

When you transmit LoRa nodes will randomly select one of between 3-8 channels (ours chooses between 3 for EU868). As you're only using an SCG this explains why some packets aren't being recieved. (And why it's important usually apart from developing that gateways are 8 channels but I know what you mean as my first gateways were only single channel).

As of this, the solution will be while you only have a single channel gateway to set the node to one frequency (not recommended and is why we haven't added blocks in yet on the Make:code library).

However as I know it can be an issue for some either being able to source Gateways or because of the cost I'll get a block added in within the next couple of days that will allow you to select 1 of the 3 frequencies to match your SCG.

Hi Ryan!
You are superb!  And this make sense. When I sent 10 packages it received 3-4, when I sent 20 it received 6-7, that is about 1/3. So since it switch between 3 channels,  I will theoretiacally get one third thru!   BTW it is no problem for me to wait a day or two

NICE WORK Ryan!!

Best wishes, Svein-Tore

Hi @Svein-Tore , I'm working on this today.

Can I ask what frequency your SCG is configured to?

[Svein-Tore]

Hi Ryan!

The frequency is 868.1

[ryanteck]

Excellent. I'll be working on this today.

[Svein-Tore]

👍

Hi @Svein-Tore , I've implemented it however if you could test it and let me know that' be great.

You'll need to find this new block which is "EU Set Freq:" under the more blocks tab. You should get the ability to set to one of the 3 channels the node supports for EU, or back to al 3 frequencies.

I tested it on my node and while on my 8 channel gateway we can see all the packets were on the same freq.

Oh, you might have to force update your library. To do this go to the Javascript tab, then at the side with the list of libraries click the re-load symbol, you'll need v0.1.37 or greater for it to work.

Hi Ryan!

So I have tested and it works fine! Now I get all the values,

THANKS A LOT!!

Excellent glad to hear! I'll close this ticket now.
