Raytac MDBT50Q-RX Bluetooth 5 LE USB Adapter Features nRF52840 WiSoC

Bluetooth 5 has been around for a while, but apart from MakerSpot CC2640 Bluetooth 5 USB dongle and Nordic Semi nRF52840 USB Dongle both for developers (and without case), it’s been hard to find Bluetooth 5 USB adapters.

So far the only proper BT 5.0 USB adapter for consumers that’s easily purchasable I know of has been Fanstel USB840F available for about $18 plus shipping. Soon enough there should at least another alternative with Raytac MDBT50Q-RX Bluetooth 5 USB adapter- also based on Nordic Semi nRF52840 WiSoC – that the company very recently announced.

The downside is that it’s not available for sale to individuals just yet. However, the company offers the Bluetooth 5 USB adapter with either Raytac logo or no logo to resellers, so I imagine it will come to market soon. So far, I could only find MDBT50Q-P1M module  on eBay for about $9 plus shipping.

There is USB module already available on aliexpress for 10€ plus 3,25€ shipping. And modules for 6,77€ (CDSENET nRF52840)

That is the one, yes. The problem is, that this one does not have any IO-s exposed, so module is preferred option for me. Just received two modules, so i will dive into ZIGBEE/Thread/BT5.

Any news on the Zigbee support? Are there firmwares available?

What are people going to use these for? (Not a rhetorical question, I really want to know). Since this can’t do classic Bluetooth, it won’t connect to people’s headphones, keyboards etc. which will lead to a poor user experience for many (most?) people.

Yup. I was wondering the same. I was looking for a small dongle that would do Apt-X HD over BT5 for use on PCs/laptops that don’t have the hardware.

Probably the cheapest way to (if there’d be firmware available) determine heart rate (ANT+) and then switch on the Philips hue lights (Zigbee) to red :D… Ok you could still do it with BTLE and a cc2531 stick for around the same price.

This module is very handy if you want to avoid BLE driver stuff in Windows. Just load a firmware with all BLE settings and software with a cdc layer and some with some AT magic (or something else) and presto chango no more driver stuff.
