Kimmo Vaisanen 5d98839092 Improve error handling & robustness ... This commit also introduces API change for disconnect(). disconnect() will now return LORAWAN_STATUS_DEVICE_OFF for successfull disconnect. * LoRaWANStack::handle_tx() can be called with NULL buffer when length is 0. This commit fixes the case where user has provided NULL buffer and length is > max_possible_size. handle_tx() now always returns LORAWAN_STATUS_PARAMETER_INVALID if given buffer is NULL pointer and length > 0. General error checking is added and some asserts are added for events.		2018-02-11 00:31:47 +02:00
