A method, a system, a controller and an apparatus are provided for managing distribution of configuration data to devices. Such a system includes a plurality of devices and a controller. The controller wirelessly broadcasts a polling signal to determine how many devices are within range of the controller. The devices that are within range receive the polling signal. Each device responds to the polling signal by sending a return signal. The received signal strength of the polling signal at the device and/or of the return signal at the controller are used to determine if a device is to be allocated to an update group. The controller sends a notification signal to the devices that have been allocated to the update group to notify them of their allocation to the group. The allocated devices are switched into a reception mode. The controller wirelessly broadcasts configuration data, which is received at the allocated devices. The configuration data is processed in the devices, if they are in the reception mode. |
