Just to complement, I saw that you there is https://shop.espruino.com/accessories/usb-bluetooth on the official shop, but it seems to have the Chipset CSR8510A10 which is not recommended if I understood well from https://www.espruino.com/Quick+Start+BLE#requirements.
Any specific recommendation from the community would be of big help here.
