Various causes are possible
After selecting your plant (or device), you are prompted with an error message saying that the connections setup to the Bluetooth® plant failed. There can be a number of reasons for this:
- The connection quality to the Bluetooth® plant is too poor.
Move the devices closer and repeat connection setup. - There are already 4 masters connected to the Bluetooth® plant.
Remove one master and try to reconnect. - There are already 2 participants connected to the device through which you want to set up a connection to the Bluetooth® plant.
Select another device or remove another communication device and try to reconnect.
