Time in microseconds to track RSSI before TX (only values of 128 or 5000 are supported)Ĭalibration value to apply to RSSI reading from the radio front endįollowing is a sample configuration for LBT enabled in AS923 plan. Only channels in this list can be used for TX when LBT is enabled. RSSI reading below which TX will be allowed The configuration can be set up through the global_conf.json file. When LBT is enabled, the device continuously monitors channels so as to transmit only when a channel is not in use.ĭOT Series devices automatically enable or disable Listen Before Talk depending on the regional requirements. The Listen Before Talk (LBT) protocol makes it possible for multiple users to share the same channel. ![]()
