6.3.5.23 Search for Remote Bluetooth
®
Device in the Wireless Network (Scan-
RemoteDevices, 0x80)
With call up, the search for remote bus modules in the wireless network is
triggered. The search process is asynchronous; i.e., the result is not immedi-
ately available. As long as the search runs, the wireless module is not avail-
able for any other function. Functions that do not use the wireless module are
carried out normally. If the search concludes, found devices are entered in a
list from which they can be individually queried with the command "GetRe-
moteDeviceMacID". The complete CoD for the WAGO Bluetooth
®
RF Trans-
ceiver 750-644 is: 0x0020F8 (hexadecimal).
To limit the search to certain devices, a Class-of-Device (CoD) can be indi-
cated. If a CoD not equal to 0 is used, only those devices are found that have
this exact CoD. If CoD = 0 is used, all devices in the environment are sought
out.
Note
The complete result of the inquiry can be read with the DLD commands.
