BLE and standard virtual COM port

[jmaja]

How can I configure a BLE service so that it's output can be read through a virtual COM port on most platforms without providing an app for these platforms?

For legacy BT there is SPP profile, but there seems to be nothing equivalent for BLE. Still many applications can read e.g. GPS over BLE and they seem to use virtual COM ports. So there must be a standard way of doing that. I just can't find it! The BLE module suppliers use custom profiles in their examples. Can any custom profile be read as a virtual COM? Probably not.

My goal is to output some data from my BLE device, maybe NMEA 0183, which could be read with apps already available. So I don't have to make software for IOS, Android, Windows etc.

There is no SPP compatible profile for BLE. Each module provider has something custom (not entirely true, some take the implementation from the chip provider) and thus you need the specific support on the other end.
