El Reenvío de Paquetes no se Inicia en IXM cuando la Radio está Desactivada

Introducción

Este documento describe cómo resolver el problema en el que el reenviador de paquetes en IXM no se inicia cuando la radio LoRa está desactivada en la IXM.

Problema

Cuando implementa un IXM nuevo e instala el paquete Actility LRR, puede ver este mensaje en el registro de seguimiento de LRR:

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

El reenvío de paquetes detiene la inicialización posterior y no intenta conectarse con el TPE o el TPW LRC.

Solución

El motivo, aunque no está claro en el mensaje de error, es que la radio no se ha iniciado en el IXM.

Esto se denomina "listo para usar".

Puede comprobar esto de la siguiente manera:

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 puede ver en la última línea, la radio está marcada como apagada.

Para encender la radio, siga esto:

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]

Luego, reinicie el reenvío de paquetes:

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 puede ver ahora en TRACE.log, el reenviador de paquetes puede iniciar:

Gateway#show packet-forwarder log name trace 250
