Important notice

We are strongly not recommended to upgrade repeaters with firmware non-listed in this article. By information of Motorola they are going to discontinue access to IPSC for all application partners. Future releases will support connectivity via Wireline only with special extra-cost developer license.

Issues with connectivity


Several times we got issue with empty password (same as on Hytera). Please check page Status of your BrandMeister Server. Field "Interpretation" will contain text "Authentication is On" it your repeater has non-empty password field. To solve this problem you need to fill some text into password field and upload codeplug into repeater then clear password and upload codeplug again. Note: BrandMeister can be configured to use authentication.

NAT traversal / firewalls / port forwarding

Mostly you have issues with your router or firewall if Field "Interpretation" contains text "XNL is not connected". In this case messages sent by server was not delivered to the repeater. BrandMeister Server is friendly for NAT traversal and it is not required any special settings.

Issues on operations

Continuous TX-ing

This situation happens when synchronous beaconing is on at your BrandMaster Server and repeater code-plug has wrong beacon duration. To solve this issue please set beacon values as shown at the picture:

Repeater does not transmit calls from the server

This situation happens when repeater code-plug has wrong value of RSSI Threshold due the specific of internal call arbitering. Also in this state the repeater detaches its time slots from the server and appears in the dashboard online, but without time slots. Any non-DMR or wrong CC signal that is higher than this value will bring the repeater in this highly unwanted state. So it is absolutely necessary to chose a value that is high enough. -100 dBm or even more. And note that it is a negative value, so -40 dBm is higher than -100 dBm :) To solve this issue please adjust RSSI threshold values as shown at the picture or even higher:
