I have been using this low cost Bluetooth dongle for almost a year with EVnotify to get live SoC data from my 2019 Hyundai Ioniq 28 kWh into ABRP. It has worked very well. The physical power button makes it easy to switch off the dongle when leaving the car.

Would be great to have native support in ABRP. Details from nRF connect attached.
