    Abstract: A method comprises a first device: receiving at least one Bluetooth Low Energy message transmitted from each of at least three second devices, each Bluetooth Low Energy message including data indicating a position of the respective second device (S2); measuring a radio parameter for each of the received Bluetooth Low Energy messages (S3); using the radio parameters and the data included in the messages to calculate the position of the first device (S4); and transmitting a Bluetooth Low Energy message including data indicating the position of the first device (S5). A further method comprises a third device: receiving at least one Bluetooth Low Energy message transmitted from each of at least three devices, each Bluetooth Low Energy message including data indicating a position of the respective device; measuring a radio parameter for each of the received Bluetooth Low Energy messages; using the radio parameters and the data included in the messages to calculate the position of the third device; receiving at least one Bluetooth Low Energy message transmitted by a first device and including data indicating a position of the first device; and causing display of the position of the first device relative to the third device.
