无线电关闭时，数据包转发器在IXM上不启动

简介

本文档介绍如何解决IXM上的数据包转发器在IXM上LoRa无线电关闭时无法启动的问题。

问题

部署新的IXM并安装Activile LRR软件包时，您可以在LRR trace.log中看到以下消息：

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

数据包转发会停止进一步的初始化，并且不会尝试连接到TPE或TPW LRC。

解决方案

错误的原因是IXM上未启动无线电，尽管从错误消息中无法清除。

这称为“开箱即用”。

您可以按如下方式检查：

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

如您在最后一行中看到的，无线电被标记为关闭。

要打开无线电，请执行以下操作：

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]

然后，重新启动数据包转发器：

Gateway#configure terminal
Gateway(config)#packet-forwarder restart
Restarted packet-forwarder
Gateway(config)#exit
*Aug 06 03:46:07: Configured from console by console

如您现在在TRACE.log中所看到，数据包转发器能够启动：

Gateway#show packet-forwarder log name trace 250
