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
...
03:40:45.990  (00834) [../main.c:954] no custom configuration file '/tmp/mdm/pktfwd/firmware/usr/etc/lrr/dyncalib.ini'

03:41:45.980  (00834) [../main.c:5346] no LRC connection during more than 1200sec => revssh

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
