2.1.1.8.1.1.1 Connecting WAGO Devices and External Devices
Slaves are divided into two groups: WAGO devices and external devices. The
WAGO devices use the real-time profile and the connection over L2CAP. Ex-
ternal devices can be connected with the master using the ad hoc profile by
SPP profile or through PAN. Both groups are therefore administered in sepa-
rate tables, even if they must be considered together with regard to simultane-
ous connections. The table for WAGO devices can accept up to seven entries.
Up to six devices are administered for external devices. A maximum of seven
simultaneous connections can exist at the same time, independently of how
many devices are listed in the tables of authorized devices using their MAC
addresses (see Table 14 and Table 15).
