Using sl_Start without a callback, returns after SL_SET_DEVICE_STARTED. In this case network operations can be started immediately.
When using sl_Start WITH a callback, the callback is made before SL_SET_DEVICE_STARTED. In this case network operations can not be started from the callback. Is there some other callback or notification that I should be using after SL_SET_DEVICE_STARTED is done where I can start network operations?
