Hello,
We are trying to connect a Tektelic Kona Micro Gateway and it proves to be a frustrating process. Here is what is at play here and the error message.
Gateway : Tektelic Kona Micro (up to date) /hereby named “device”
Chipstack-gateway-bridge : Installed and running on Device
Chirpstack Instance : Full install and functional on GCS VM
after installing the bridge and updating the config.json file and .toml file, we get an error message:

chirpstack-gateway-bridge.toml
This configuration provides a Semtech UDP packet-forwarder backend and
integrates with a MQTT broker. Many options and defaults have been omitted
for simplicity.
See https://www.chirpstack.io/gateway-bridge/install/config/ for a full
configuration example and documentation.
[general]
debug=5, info=4, warning=3, error=2, fatal=1, panic=0
log_level=5
Log to syslog.
When set to true, log messages are being written to syslog.
log_to_syslog=true
Gateway backend configuration.
[backend]
Backend type.
type=“semtech_udp”
Semtech UDP packet-forwarder backend.
[backend.semtech_udp]
ip:port to bind the UDP listener to
Example: 0.0.0.0:1700 to listen on port 1700 for all network interfaces.
This is the listener to which the packet-forwarder forwards its data
so make sure the ‘serv_port_up’ and ‘serv_port_down’ from your
packet-forwarder matches this port.
udp_bind = “127.0.0.1:1700”
Integration configuration.
[integration]
Payload marshaler.
This defines how the MQTT payloads are encoded. Valid options are:
* protobuf: Protobuf encoding (this will become the ChirpStack Gateway Bridge v3 default)
* json: JSON encoding (easier for debugging, but less compact than ‘protobuf’)
marshaler=“protobuf”
MQTT integration configuration.
[integration.mqtt]
Event topic template.
event_topic_template=“gateway/{{ .GatewayID }}/event/{{ .EventType }}”
Command topic template.
command_topic_template=“gateway/{{ .GatewayID }}/command/#”
MQTT authentication.
[integration.mqtt.auth]
