Introduction

This document describes how to resolve the issue where the packet forwarder on the IXM does not start when LoRa radio is off on the IXM.

Problem

When you deploy a fresh IXM and install the Actility LRR package, you can see this message in the LRR trace.log:

Gateway#show packet-forwarder log name trace 250

...

The packet forward stops furter initialisation and does not attempt to connect to the TPE or TPW LRC.

Solution

The reason, although not clear from the error message, for the error is because the radio hasn't been started on the IXM.

This is called "out-of-the-box".

You can check this as follows:

Gateway#show radio

LORA_SN: FOC203310DG

LORA_PN: 95.1602T00

LORA_SKU: 868

LORA_CALC: <135,123,115,107,99,95,91,87,78,70,62,53,45,41,37,33-133,120,112,104,96,92,88,84,75,67,59,51,43,39,35,31>

CAL_TEMP_CELSIUS: 34

CAL_TEMP_CODE_AD9361: 90

RSSI_OFFSET: -204.07,-203.78

LORA_REVISION_NUM: A0+

RSSI_OFFSET_AUS: ▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒

radio status:

off

As you can see in the last line, the radio is marked as off.

In order to turn the radio on, follow this:

Gateway#configure terminal

Gateway(config)#no radio off

Gateway(config)#exit

*Aug 06 03:45:28: Configured from console by console

Gateway#copy running-config start

!

Copy 333 bytes took 00:00:01 [hh:mm:ss]

Then, restart the packet forwarder:

Gateway#configure terminal

Gateway(config)#packet-forwarder restart

Restarted packet-forwarder

Gateway(config)#exit

*Aug 06 03:46:07: Configured from console by console

As you can see in the TRACE.log now, the packet forwarder is able to start:

Gateway#show packet-forwarder log name trace 250
