Failed to start the concentrator #254

Closed sokolbiba closed 7 years ago

sokolbiba commented 7 years ago

Hi everyone, I am trying to setup a new ic880a (SPI version) gateway using a raspberry pi 3 and the latest version of the raspbian https://www.raspberrypi.org/downloads/raspbian/ (lite version). After downloading the lora_gateway and packet forwarder and compiling them I get the following error (see picture below). Do you have any idea what might be going wrong? Thank you in advance.

I'm going to close this issue as it is not related to the LoRa Server codebase. Please use https://forum.loraserver.io for support questions :-) Hint: your question might already been answered: https://forum.loraserver.io/t/lora-packet-forwarder-doesnt-start/231.

Hi @sokolbiba,

before running the packet forwarder you have to bring the iC880A Concentrator in an initial state (reset). I made this by running shell script running prior executing the packet forwarder.

!/bin/bash

echo "17" > /sys/class/gpio/export echo "out" > /sys/class/gpio/gpio17/direction echo "1" > /sys/class/gpio/gpio17/value sleep 5 echo "0" > /sys/class/gpio/gpio17/value sleep 1 echo "0" > /sys/class/gpio/gpio17/value

After that the packet forwarder should run without any problems. You can find some more information about preparing the reset pin control in the iC880A doc under https://wireless-solutions.de/images/stories/downloads/Radio%20Modules/iC880A/iC880A-SPI_QuickStartGuide.pdf starting at the end of page 9.

Hi @maximilianschwab I tried waht you suggested me and I still get the same error. I do not understand why but while using the ttn packetforwarder it is performing very well.

@maximilianschwab I was misconfiguring the reset pin. Thank you for your help :)
