Introduction

Este documento descreve como resolver o problema em que o encaminhador de pacotes no IXM não inicia quando o rádio LoRa está desligado no IXM.

Problema

Quando você implanta um novo IXM e instala o pacote Acutility LRR, você pode ver esta mensagem no arquivo LRR trace.log:

Gateway#show packet-forwarder log name trace 250

...

O encaminhamento de pacotes interrompe a inicialização adicional e não tenta se conectar ao TPE ou ao TPW LRC.

Solução

O motivo, embora não esteja claro na mensagem de erro, do erro é porque o rádio não foi iniciado no IXM.

Isso é chamado de "pronto para uso".

Você pode verificar isso da seguinte maneira:

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

Como você pode ver na última linha, o rádio está marcado como desligado.

Para ligar o rádio, siga este procedimento:

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]

Em seguida, reinicie o encaminhador de pacotes:

Gateway#configure terminal

Gateway(config)#packet-forwarder restart

Restarted packet-forwarder

Gateway(config)#exit

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

Como você pode ver no TRACE.log agora, o encaminhador de pacotes pode iniciar:

Gateway#show packet-forwarder log name trace 250
