Hi Saket!
Are there any plans to support bluetooth and BLE via some Expo apis?
We do plan on supporting this! It's a very popular feature request: expo.canny.io/feature-requests/p/bluetooth-api
No timeline for it yet but we're making our way towards it.
Any plans for Expo or some of your apis eventually becoming separate libraries so we can only use the parts we need
Some users have started to do this , eg: react-native-camera is the Camera component extracted from the Expo codebase.
As for only using the parts you need, we plan on making it possible to opt-in to only the APIs that you need in the build step, to help reduce the size of the binary.
(even if at a extra cost per library)?
No plans for charging for that.
