1. A method comprising:
transmitting, by a device and via a LoRaWAN network to an application, a series of sensor measurements captured by the device, each sensor measurement having an associated timestamp based on a clock of the device;
receiving, at the device and from the application, an indication that at least a portion of the series of sensor measurement were not received by the application;
determining, by the device and for those sensor measurements not received by the application, timestamp differences between timestamps for those sensor measurements not received by the application and a current time of the clock of the device, after receiving the indication; and
resending, by the device, the portion of the series of sensor measurements to the application and the timestamp differences.
