| + | |||
| + | Scan a range of channels and compile a list of channel from which an ack has been received. The command START_SCAN_CHANNELS should be executed first with start being the first scanned channel and stop the last one. Those should be within 0 to 125. The data is the packet payload sent on each channel, it should be at least one byte long. | ||
| + | |||
| + | All parameters, except the channel, are used unmodified during the scan. If the datarate is set to 2MBPs the scan is done every second channel. To get the list of channel that answered GET_SCANN_CHANNELS should be called just after a scan. Up to 63 bytes are returned corresponding to up to 63 channels on which the packet was acknowledged. | ||
| + | |||
| + | Note. After scanning the channel will be let to the last scanned channel. | ||
