The method includes operating a wireless communication interface of the aerosol provision device in a listening mode. During operation of the listening mode, data is received data from the wireless communication interface of another aerosol provision device. The received data is stored in a memory of the aerosol provision device. A connectionless-state advertising packet that includes information relating to an identity and advertising state of the aerosol provision device is created using the wireless communication interface of the aerosol provision device and transmitted via the wireless communication interface. A connectionless-state request packet is received from a remote wireless device, via the wireless communication interface. In response to receiving the request packet, a connectionless-state response packet is created using the wireless communication interface and the response packet is transmitted via the wireless communication interface. At least one of the advertising packet and the response packet includes the received data from the memory and data generated by the aerosol provision device and stored in the memory. ## Claims ### Claim 1 A method for an aerosol provision device, the method comprising: operating a wireless communication interface of the aerosol provision device in a listening mode; during operation of the listening mode, receiving data from the wireless communication interface of an other aerosol provision device; storing the received data in a memory of the aerosol provision device; creating, using the wireless communication interface of the aerosol provision device, a connectionless-state advertising packet that includes information relating to an identity and an advertising state of the aerosol provision device; transmitting the advertising packet via the wireless communication interface; receiving a connectionless-state request packet from a remote wireless device, via the wireless communication interface; responsive to receiving the request packet, creating, using the wireless communication interface, a connectionless-state response packet; and transmitting the response packet via the wireless communication interface, wherein at least one of the advertising packet and the response packet includes the received data from the memory and data generated by the aerosol provision device and stored in the memory; and wherein the method further comprises: determining, prior to storing the received data in the memory of the aerosol provision device, a number of aerosol provision devices from which data has been previously received and stored in the memory of the aerosol provision device; and if the number of aerosol provision devices from which data has been previously received is greater than or equal to a predetermined number, deleting at least the oldest data prior to storing the data received from the other aerosol provision device. ### Claim 2 (depends on 1) The method of claim 1, wherein the received data includes information describing usage characteristics of the other aerosol provision device. ### Claim 3 (depends on 2) The method of claim 2, wherein the usage characteristics of the other aerosol provision device comprise one or more values of: battery properties, aerosol generation properties, aerosol medium properties, aerosol generation event properties, and erroneous or abnormal behavior properties. ### Claim 4 (depends on 2) The method of claim 2, wherein the usage characteristics of the other aerosol provision device are recorded and stored in the memory during use of the other aerosol provision device. ### Claim 5 (depends on 1) The method of claim 1, wherein the at least one of the advertising packet and the response packet which includes the received data from the memory and data generated by the aerosol provision device and stored in the memory includes a selection of the received data stored in the memory and all of the data generated by the aerosol provision device and stored in the memory. ### Claim 6 (depends on 1) The method of claim 1, wherein the at least one of the advertising packet and the response packet which includes the received data from the memory and data generated by the aerosol provision device and stored in the memory includes a selection of the received data stored in the memory and the data generated by the aerosol provision device and stored in the memory. ### Claim 7 (depends on 5) The method of claim 5, wherein the selection comprises information relating to a particular usage characteristic of the other aerosol provision device. ### Claim 8 (depends on 5) The method of claim 5, wherein the selection comprises storing less than all of the received data. ### Claim 9 (depends on 1) The method of claim 1, further comprising: deleting, prior to storing the received data in a memory of the aerosol provision device, any data previously received from the other aerosol provision device and stored in the memory of the aerosol provision device. ### Claim 10 (depends on 1) The method of claim 1, wherein at least one of the data generated by the aerosol provision device or the data received from the other aerosol provision device includes location data for the respective aerosol provision device. ### Claim 11 (depends on 1) The method of claim 1, wherein the at least one of the advertising packet and the response packet which includes the received data from the memory and data generated by the aerosol provision device and stored in the memory includes a timestamp. ### Claim 12 (depends on 1) The method of claim 1, further comprising: deleting, after a predetermined period of time, the received data stored in the memory of the aerosol provision device. ### Claim 13 (depends on 1) The method of claim 1, wherein the wireless communication interface is a Bluetooth low energy communication interface. ### Claim 14 (depends on 1) An aerosol provision device comprising: a processor; a wireless communication interface; and memory containing instructions which, when executed by the processor, performs the method of claim 1.
