Error while sending message with Raspberry Pi

[Haves1001]

I tried to execute the following test code on my raspberry pi:

bishbosh_clientId=12

bishbosh_connection_handler_CONNACK()
{
    # Set up some subscriptions... another implementation could read from a standard file
    bishbosh_subscribe \
        '/topic/qos/0' 0 \
        '/topic/qos/1' 1 \
        '/topic/qos/3' 1

    bishbosh_unsubscribe \
        '/topic/not/wanted' \
        '/and/also/topic/not/wanted'

    # Publish a QoS 0 message
    # On topic a/b
    # Unretained
    # With value 'X'
    bishbosh_publishText 0 'a/b' no 'My message'
    #bishbosh_publishFile 1 'a/b' no '/tmp/test.dat'
}

bishbosh_connection_handler_PUBLISH()
{
    echo "Message received: retain=$retain, QoS=$QoS, dup=$dup, topicLength=$topicLength, topicName=$topicName, messageLength=$messageLength, messageFilePath=$messageFilePath"
}

bishbosh_connection_handler_noControlPacketsRead()
{
    # This event happens every few milliseconds - use this to publish some messages, change subscriptions or reload our configuration. Perhaps we could monitor a folder path?
    # bishbosh_publishText 0 'nowt' no 'hello world'
    echo 'No Control Packages Read' 1>&2
}

And get the following error. This is caused by bishbosh_publishText. Is there a mistake I don't see?

Thanks for taking time the time to report a problem. It looks like an undeclared variable. These can be quite hard to debug in shell script. Could you modify your script to have a set -x (eg as the second line of bish-bosh) and publish the resultant stderr output here or as a gist, please?

[Haves1001]

Hopefully I got it right. Does this gist help you?

Ta. Let me start taking a look. I'm mostly tidied up until Monday, so I may not get back to you until then.

[Haves1001]

Ok thanks anyway for your effort and your time. That is some great piece of software you developed!

[raphaelcohn]

I've made a bug fix and a new release - https://github.com/raphaelcohn/bish-bosh/releases/tag/release_2015.0629.0920-4 . Having problems with network connectivity at the moment, so there may still be issues. Could you test and let me know?

[Haves1001]

This seems to be working. At least it isn't throwing an error anymore.

Unfortunately I don't receive the messages I sent. As far as I read the logs properly.

sudo ./mqtt/bish-bosh/bish-bosh --verbose 2 -- /tmp/bish-bosh2.example

But it seems like they are sent.

Could you send me another set -x gist? On 29 Jun 2015 13:53, "Henning von See" notifications@github.com wrote:

Thanks, let me know if you need more information.

[raphaelcohn]

Sorry I haven't been able to look at this yet.
