When service shutdown, can I use cloudpebble to develop pebble app and install on my pebble watch for personal use?
Is it possible to open magnetometer API before shutdown service?
Cloud Pebble is still available (for now) and if you develop a Pebble app with it you can just download and install the package to your own Pebble. I have done this several times.
I’m not sure what the question means.
The magnetometer doesn’t require any external support, but be aware that the Pebble 2 doesn’t have one.
