MQTT-SN Gateway over ZigBee #168

Closed Yamnkelani closed 4 years ago

Yamnkelani commented 4 years ago

Hi

I have an issue starting up my MQTT-SN Gateway over ZigBee

I downloaded the paho MQTT-SN gateway and attempted running the gateway over ZigBee. I simply configured the gateway as follows:

BrokerName=iot.eclipse.org
BrokerPortNo=1883
BrokerSecurePortNo=8883

ClientAuthentication=NO
AggregatingGateway=NO
QoS-1=NO
Forwarder=NO

PredefinedTopic=NO

GatewayID=1
GatewayName=PahoGateway-01
KeepAlive=900

# XBee
Baudrate=38400
SerialDevice=/dev/ttyUSB0
ApiMode=2

# LOG
ShearedMemory=NO;

However, when I run the gateway, I get the following error message

terminate called after throwing an instance of 'MQTTSNGW::Exception' what(): Can't open the sensor network.

I don't know what I am missing.

Hi,

iot.eclipse.org was move to mqtt.eclipse.org. So, change BrokerName=iot.eclipse.org to BrokerName=mqtt.eclipse.org

Hi .

I changed the broker name. It still throws the error

ty4tw commented 4 years ago

Hi, It might be a setting problem of XBee module. check the baudrate and API mode are same as gateway.conf.

Yamnkelani commented 4 years ago

I got it to work. I changed the "SENSORNET:=udp" to "SENSORNET:=xbee" on the makefile and rebuilt the gateway. Thanks

Hi,

You don't need to change the Makefile. Just enter make SENSORNET=xbee
