Abstract:
A method for wireless communication comprising:providing a first unit and a second unit for communication over a wireless communication link; assigning an identical identifier to the first and second units; constructing a data message having control data at the first unit, the data message including a plurality of data bytes, a portion of the control data corresponding to the identifier; splitting the data message into a plurality of message portions at the first unit; transmitting the message portions from the first unit to the second unit; receiving the message portions at the second unit; assembling control data from the message portions to form a control message at the second unit; comparing the identifier portion of the control message with the identifier assigned to the second unit, when the identifier portion of the control message matches the identifier assigned to the second unit, the second unit enters an in-synchronization state, when the identifier portion of the control message is different from the identifier assigned to the second unit, the second unit enters an out-synchronization state; and searching at least one prior control message for the identifier assigned to the second unit when the second unit is in the out-synchronization state, synchronizing with a matching identifier when the matching identifier is found in the prior control messages and resynchronizing with the first unit when the prior control messages are free of the identifier.
