can anyone suggest their working Linux bluetooth USB dongles to connect to Pinetime?

[jahway603]

I really am loving my new Pinetime watch, but I've been having trouble connecting to it with the bluetooth USB dongles I have on Linux systems. The dongles are able to see other devices, and will eventually see the Pinetime, but it continues to fail to pair or connect with it. I've been able to use Gadgetbridge on Android to flash my Pinetime, but that requires the location permission so I would prefer to flash my Pinetime with a regular computer.

What bluetooth USB dongles (or chipsets) are other Pinetime users using on Linux to flash their watches?

I've tried three or four different dongles, Fedora on an (admittedly old) Acer Aspire V5.
So far, no success with linking - can't even see it.

This is USB dongle that I have on my desktop pc and it does work:

ID 0a5c:21e8 Broadcom Corp. BCM20702A0 Bluetooth 4.0

Make sure what ever unit you are purchasing has the Bluetooth Low Energy (BLE) capability.

I did some digging around and, after reading many reviews, picked up an Edimax BT-8500 for $16 USD on Amazon (because it wasn't cheaper on newegg and I'd expect a counterfit version on eBay or other sites). Anyhow, I was able to flash the latest InifiniTime on a brand new pinetime with this new bluetooth adapter that just arrived. Others please share what works or what doesn't work for you.

This bluetooth adapter was tested successfully with siglo on Arch linux.
