The monitors can include a plurality of sensors and wireless and/or wired communication circuitry to transmit the sensor data to a receiver. The receiver can be connected to the maintenance monitoring infrastructure, where the sensor data can be used to perform maintenance data analysis and provide artificial-intelligence-based maintenance recommendations. In some embodiments, the monitors can be battery-powered. An efficient wireless communication method between monitors and receivers can include splitting a payload into packets, transmitting a plurality of packets, sequentially, waiting for receipt acknowledgement from the receiver and resending a missing packet, before sending a additional bursts. ## Claims ### Claim 1 A method of communication between a monitor and a receiver, comprising: receiving a payload; determining a packet size, based at least in part on an underlying communication framework; dividing the payload into a plurality of packets; sending a payload transmission request to the monitor; sending a burst of packets to the receiver, the burst comprising a plurality of the packets; awaiting a first period of time for an acknowledgement of receipt of the burst from the receiver; when no acknowledgement is received, awaiting a second period of time, before resending one or more packets to the receiver; the receiver determining a missing packet, based at least in part on a sequential index of each received packet; transmitting a missing packet index number to the monitor; and the monitor, sending the missing packet to the receiver. ### Claim 2 (depends on 1) The method of claim 1 further comprising: the monitor transmitting a payload end message to the receiver; awaiting an acknowledgement receipt of the payload end message; when an acknowledgement is not received, the monitor resending the payload end message if previous attempts of sending the payload end message does not exceed a selected threshold; and when an acknowledgement is not received, the monitor canceling the transmission with a failure message if the resending of the payload end message in the previous attempts of sending the payload end message equals or exceeds a selected threshold. ### Claim 3 (depends on 1) The method of claim 1, further comprising: generating a random number; assigning the random number to the payload as the payload identifier; transmitting the payload identifier along with each packet of a payload; the receiver, checking the payload identifier against prior received payload identifiers; and the receiver, issuing a repeated payload identifier message is the payload identifier has previously been used for another payload. ### Claim 4 (depends on 1) The method of claim 1, further comprising: the receiver, sending a payload transmission request acknowledgement to the monitor; the receiver, waiting for a packet; the receiver receiving a packet and sending an acknowledgement of the packet to the monitor; the receiver, sending a request for a missing packet to the monitor; the receiver, waiting a first period of time before resending the request for the missing packet; the receiver, resending the request up to a selected threshold; the receiver, receiving a packet; and the receiver, issuing an acknowledgement message to the monitor; the monitor sending a payload end message; the monitor sending a payload end message acknowledgment to the monitor; the receiver, waiting a period of time for the payload end message and resending a payload end message request for a number of tries less than a threshold; and when the receiver does not receive the payload end message after the threshold number of tries, the receiver issuing a failure message. ### Claim 5 (depends on 1) The method of claim 1, wherein the underlying framework comprises the physical layer and the physical layer abstraction of an open system interconnection (OSI) model. ### Claim 6 (depends on 1) The method of claim 1, wherein each packet comprises metadata, and the metadata comprises the size of each packet, and the method further comprises: the monitor, generating a monitor checksum for a plurality of packets; the receiver, generating a receiver checksum for the plurality of the packets; the receiver, matching the checksums; and generating a success or failure message, based at least in part on whether checksums match. ### Claim 7 (depends on 1) The method of claim 1, wherein each packet comprises metadata, wherein the metadata comprises one or more of the size of a packet, a sequential index of the packet, a burst checksum, and a payload checksum.
