@neverdie it's this link, in the description on aliexpress you can see the internal PCB "module"
https://www.digikey.com/product-detail/en/tag-connect-llc/TC2030-CLIP/TC2030-CLIP-ND/2605371? Plug of nails?

I dropped "Bluetooth" from the title of this thread because the thread instead evolved into the MySensors alternative to Bluetooth.
-
How hard, or how much work, would it be to create a version of the MySensors gateway that works on one of those dongles?

Really? So something like:
- Upload gateway sketch to it (how?)
- Select "serial connection" in Domoticz?

i don't think you need extraordinary soldering skills, pads on bottom looks easy ;) (pretty sure these are the programming pads)
The right question, imho, would be: can you expect from this dongle the range you would expect from a gateway ?? regarding chip antenna performance and maybe its gnd counterpoise..

@Toyman yep, this confirms what i said, not difficult to access.
I didn't read the description..just looking at the pcb layout was enough to tell me poor rf range + no basic usb spec design rules (latter point is maybe not the most critical for most of people, but it just shows 1) designer wasn't aware ?? 2) this is what you get for cheap money, whereas missing parts would have cost few cents..).
Just saying, because maybe this dongle can work well enough for some people. -

Looks as though there is also a new DK for the nRF52840 as well:

just not in stock.Looks like HolyIOT is ahead of the curve on this chip.

@neverdie I would suggest holding off on purchasing a new nRF52840-PDK until the final silicon is released.
Oh! It's still not?

@scalz
I would be interested in any range testing in regard to this dongle. For ground it has whatever it is that it is plugged into. (PC, SBC, USB extention cable, etc) There will be a nRF52840 based dongle out soon. See picture above. This dongle will need to be programed over the SWD lines. No Segger on board this one..! -
@Nca78
Getting rid of the ground plains around the entire module hugely improved the range. Had to stap back to AAA batteries to fit on the board. But I'm happy with the way it's going (AA is still possible but not soldered on it just doesn't fit enough in the wall socket) -
Very nice. Looks professional!

Very nice indeed. I thought ground plains improve the range
He's talking about the ground plane around the nrf5 module, not on the full board ;)
