FIELD: physics.
SUBSTANCE: invention relates to wireless communication. Result is achieved by the fact that in the portable device communication method, if the second Bluetooth connection is disconnected between the user device and the portable device, establishing a first Bluetooth connection between the network connection device and the portable device, such that the network connection device can direct the first information to the portable device through the first Bluetooth connection, directed by the user device through a third communication connection with the network connection device.
EFFECT: technical result is implementation of indirect communication between user device and portable device using network connection device, so that user device and portable device are not limited by communication range.
