Ha ha - you beat me to it!

It doesn't:

You'd have to as Ruuvi about that!

"BT5" covers a lot of options - it does not necessarily include Coded-PHY

Again, you'd have to ask Ruuvi about that.

My understanding is that you can completely erase the chip, and program it with whatever you like - but you'd have to check with Ruuvi to be sure.

If the RuuviTags based on nRF52832, I don't think it supports Bluetooth 5.0 Long Range. The tag can still offer other Bluetooth 5 feature, such as 2MBps, AE, CSA#2.

I would suggest you to contact them directly, we are not expected to comment about our customer's products.

I can understand that.

We're trying to use beacons as sensors. Looks like the Long Range feature is still not as available as we'd need it to be. But what about the BT5 LE 2M PHY layer? Do we have that available on Ruuvi Tags?

That makes sense, hence why one can't find them easily.

And what about the "BT5 ready" spec of the RuuviTags?

Also, beacons are, perhaps, most commonly used in location systems - where long range is precisely what you don't want!

I don't think there are many Beacons on the market having Long Range because the feature is not support by most of the mobile phones.

You may want to look into our module maker, you can find here.

Regarding gateway, one example could be the Cascade gateway from Rigado: https://www.rigado.com/cascade-gateway/ It's a white label solution that you can put your brand on.

That's it!

By "long range" I thought you were talking specifically about the BLE 5.0 Long Range features (Coded PHY).

Hi Awneil, thanks for answering.
I'll be checking the news archive.

Actually, the difference of the 52840 is exactly its performance for long range, which is important for our use cases (mainly cold chamber and refrigerators). But it's fairly new for us too, so if you have any suggestions I'm very open to hear them.

Check out the Nordic news archive - they often feature announcements of products using Nordic chips.

But, in general, product manufacturers don't publicise what parts they use.

But why does it matter what chips these things use? Surely, all a user needs to know is the performance & compatibility specs?
