Reading the MAC ID of a Remote Device

GetRemoteDeviceMacID, 0x81
This command is used to access a list of 750-644 I/O modules or Bluetooth
devices visible in the area and to query the Bluetooth
750-644 I/O module or Bluetooth
execution of a scan process with the command "ScanRemoteDevices", which
initiates creation of this list. If an attempt is made to access the list before the scan
process is complete, the command responds with MBX_CMD_DENIED_BUSY.
In this case, the query should be repeated after a few seconds.
If this command is used with a Mailbox size of 6 bytes, the command only returns
the number of devices found. To query the MAC IDs of the devices, however, the
block transfer can be used (see DLD_Start, DLD_Cont, DLD_End commands).
Execute the "ScanRemoteDevices" beforehand!
Before calling up "GetRemoteDeviceMacID", the "ScanRemoteDevices"
command must be executed (see appendix "Scanning for a Remote Device in the
Wireless Network").
