we have detected that Bluetooth isn´t stable with all peripherials. For example my MacBookPro…I can see the EDGE and I can connect with it but the connection break off every view seconds. Some other very different devices can´t connect not at all.
We tested it on different EDGE+Captain and also on EDGE-V (Android last ROM version).
We tested it also on Geebox and VIM2. There it works fine.
