Set The Qos Settings (Setconnectionqos, 0X89) - WAGO I/O-SYSTEM 750 Manual

6.3.5.32

Set the QoS Settings (SetConnectionQoS, 0x89)

This command assigns the settings of the Quality-of-Service (QoS) for a con-
nection. The settings do not take effect until the module is switched over to
master mode.
Note
The master can connect to a maximum of 3 slaves with activated QoS. QoS
can only be set for WAGO devices. It improves latency by reducing devia-
tions (outliers).
Since the Bluetooth
optimized for maximum performance, the influence on time behavior in the
real-time profile is marginal. Therefore, it is recommended that you keep the
factory setting MBX_BQM_NONE.
