Andrew,
In the below table, the
sync wordis basically the first byte in a transmitted packet and is used to lock onto a signal that is destined for you. All public networks use the same sync word. For a custom private implementation, a different sync word can be used to distinguish the difference.The
Join response timeis the time delay between when the lora network server receives a join request and when it transmits the join accept. In a traditional public network, the server would be in the cloud somewhere, so extra time is needed for the join request to go from the gateway to the server and back. But for our private implementation, we reduce the delay because the server actually resides on the gateway.Mode
Private
Public
Sync word
0x12
0x34
Join response time
1 & 2 seconds
5 & 6 seconds
Does that help?
Anthony,
You can see what’s happening in
/var/log/messages.It’s likely not working because you have an LTE SIM, but the Conduit doesn’t support LTE.
If you have more questions relating to compatability, open a support case here: http://support.multitech.com/

Tim,
It looks like you actually have the AEP version of Conduit (which is built on top of mLinux). Here’s the getting started guides for AEP:

Sean,
To connect to Bluemix using the MQTT node in Node-RED, you’ll need to (1) have a Bluemix account, (2) create a Bluemix app, (3) add the “Internet of Things” service to the app, (4) Launch the IoT service and add a device, (5) save the device credentials, (6) use documentation here: https://docs.internetofthings.ibmcloud.com/messaging/devices.html to configure the MQTT node in Node-RED.
Here are some screenshots:

Hello Michal,
Unfortunately, what you described is not possible right now. We currently only support LoRa Class A which doesn’t allow point (mdot) to point (mdot) communication. A gateway & network server is required for Class A.
Having said that, we plan on implementing Class C in the future which would allow for the connection you described. However, we don’t have an expected date for that yet. Secondly, Class C or not, LoRa isn’t going to work well for your application because LoRa is designed for sensor type applications where data rate is low and latency can be high. Especially being in Europe which has transmit duty cycle restrictions that limit how often you can transmit a packet. For example, a payload size of 50 bytes might only can be transmitted every 30 seconds depending on your settings.
In any case, the maximum effective throughput in Europe is around 550 bps.
Hope this helps!
