Redis issue, can't generate uuids

[mcinnes01]

Hi @brianehlert

Just being playing with meshblu trying to generate a UUID for an arduino with:

curl -X POST -d "type=firmwareController&payloadOnly=true&name=Arduino" http://UbuntuServer:3000/devices

Also tried generating a UUID with NodeBlu and adding a new MeshBlu server and using the generate option to no avail. I get the following:

This is the error logs on the server

Any ideas what I am doing wrong?

Many thanks

If I recall properly you are running Windows, right? I ask since my REST commands in are PowerShell ;-)
Did you set the UUID and token in the sketch prior to uploading the sketch to the Arduino? You need that information to be able to do anything with it. And you have to modify the object and set it as payload only.

Here is my test. It is basically a walkthrough scenario.
(NOTE: This is PowerShell folks!)

check 'status' of Meshblu
Invoke-RestMethod -URI http://<your meshblu>:3000/status -ContentType "application/json" -Method Get

Add yourself as a 'developer' to a Meshblu instance so that you can query objects (a 'device' is simply an object) - this is the minimum
$body = @{ "type" = "user" }

better way to add yourself:
$body = @{ "type" = "user"; "email" = "[email protected]"; "name" = "Brian Ehlert" }

$json_body = $body | ConvertTo-Json

$objMe = Invoke-RestMethod -URI http://<your meshblu>:3000/devices -ContentType "application/json" -Body $json_body -Method Post

"$objMe" contains the uuid and token that needs to be used in the header to 'authenticate'

$meAuthHeader = @{ meshblu_auth_uuid = $objMe.uuid; meshblu_auth_token = $objMe.token }

list 'public' devices
$allDevices = Invoke-RestMethod -URI http://<your meshblu>:3000/devices -Headers $meAuthHeader -Method Get $allDevices.devices

claim a device
Invoke-RestMethod -URI ("http://<your meshblu>/claimdevice/" + $device.Uuid ) -ContentType "application/json" -Headers $meAuthHeader -Method Put

$device.Uuid is something that you should already know. Since you own the arduino.

I see Redis connection refused.
Your Redis server should not be asking for authentication and you should not have it defined in your configuration.
I am assuming that you copied my gitAppliance.sh, Ubuntu_meshblu.conf, and meshbluConfig.js to your home directory and ran gitAppliance.sh

Hi @brianehlert

I sure did, I didn't change the config and left it as is, just renaming as you described to "meshblu.conf".

Following the powershell commands I get this, which I guess is due to the redis issue?

Here is the files in the home directory as you described and I ran ./gitAppliance.sh

Is there some config change required in relation to redis?

Many thanks

The script should have installed a local Redis server and also be connecting to it on 'localhost'
And it is possible that 'localhost' is messed up in the hosts file.

If you go to /var/www/meshblu and edit config.js nano /var/www/meshblu/config.js
You can comment out the four redis configuration lines. Redis is not important.
Then save with ctrl + x and be sure to say yes.

Then reboot sudo shutdown now -r

The REST error. Your screen shot looks like you missed a step:
$json_body = $body | ConvertTo-Json

Prior to the POST

Hi @brianehlert

This is my hosts file I did edit it following some instructions about setting up ubuntu

I'll try disabling it for now, but it would be cool to work out what's going wrong.

I'll try without and let you know how I get on.

Thanks again for the help!

Hi @brianehlert

I commented out the redis config, rebooted and tried the steps described above and I get the following error:

Interestingly if I check the status I still get "online"

Not sure why it doesn't want to play ball, everything is vanilla with no extras installed?

Many thanks

Hard to truly know without seeing it myself, since this is an app talking to another service.
Be sure that your $body and $json_body are populated. But then I would expect and unauthenticated error.
try formatting the $body a bit differently.
try only: $body = @{ "type" = "user" }
Then convert to json, then feed in.
I honestly have not had that problem with Windows 8.1 (PowerShell v4)
