Can multiple Metracell BT PRO devices with different names be paired to the PC?

Each Metracell BT PRO battery tester is paired to the PC under the name "BTPRO". Each newly paired device is assigned a unique incoming and outgoing COM port.
In order to distinguish each Metracell BT PRO device from each other in the Windows Bluetooth device list, the device name can be renamed to a unique name.

To change the device name, connect the corresponding device to the PC by turning on the device. If the device has not yet been paired with the PC, pair the device as described in the operating instructions and leave it switched on.
In Windows Settings → Bleutooth and Other Devices → Devices and Printers, right-click the device you want to rename and select Properties. In the properties window, select the Bluetooth tab. Change the device name "BTPRO" to a unique name, e.g. BTPRO, serial number or company internal number, associated COM port Outgoing. Click Apply. Select the "Services" tab. After a few seconds, the new device name is applied and appears in the Windows Bluetooth device list.

Using multiple devices:

One or more devices can be connected to the PC at the same time. In the BT PRO Manager software, select the outgoing COM port of the device to which you want to transfer the data or from which you want to read the data.
