172 Appendix WAGO-I/O-SYSTEM 750750-644 Bluetooth® RF-TransceiverManualVersion 2.0.0, valid from FW/HW Version 03/0312.3.6.4 Entering a Device in the Table of Allowed DevicesAllowRemoteDevice, 0x83This command is used to allow a remote 750-644 I/O module or Bluetooth® SPPdevice access to the local 750-644 I/O module. The MAC ID of the remote deviceis also entered in a table of the Bluetooth® subsystem. Two types of devices aredifferentiated. Both types are entered in different tables:• 750-644 I/O modules for “Real-Time Communication” mode:WAGO_DEVICE (0x20 … 0x26)• Bluetooth® SPP devices for “Ad-hoc Communication” mode*):EXTERNAL_DEVICE (0x10 … 0x15)*) Bluetooth® specification: Device supports the “Serial Port Profile” (SPP)Access permissionBefore an entered 750-644 I/O module is actually authorized access, it must beenabled using the command “BindRemoteDevice”.Access permission can be revoked using the command “UnbindRemoteDevice”without requiring deletion of the device from the table.• Entries can be deleted from the table by overwriting with the MAC ID00:00:00:00:00:00. The respective slot is populated with 0. No data istransmitted to it.• Changes to the device blocks do not change anything in the processimage mapping.• A MAC ID (exception: MAC ID 00:00:00:00:00:00) may never occurmore than once in a table.ConditionsMailbox size Mode Device role Saveconfig.Reboot6 12 18 Config.
