I'm trying to push data up to Azure IoT Hub and having some difficulties with the examples I've found on the forum and openrb.com so far.
Does anyone have an example for connecting to Azure IoT Hub with MQTT?

So no-one has successfully managed a connection towards Azure IoT Hub with LM/SL via MQTT?
I've tried this:
http://openrb.com/mqtt-client/#codesyntax_1
But it doesn't give me any feedback what's wrong, nothing in error log. I'm also doubting it's running at all, as log in between code that should be executed doesn't give results. In Microsofts cloud there are no indications of a connection.

Can you send client id, MQTT username and password via PM? Info on username/password format: https://docs.microsoft.com/en-us/azure/i...tt-support

Thanks!
First, you need to update MQTT library packages:
New CPU:
https://dl.openrb.com/pkg/libmosquitto_1...1_imx6.ipk
https://dl.openrb.com/pkg/luamosquitto_0.3-2_imx6.ipk
Old CPU:
https://dl.openrb.com/pkg/libmosquitto_1.4.15-1_mxs.ipk
https://dl.openrb.com/pkg/luamosquitto_0.3-2_mxs.ipk
Here's a minimal example that you can use, don't forget to change device_id, broker, username and password parameters. You also need to upload azure.crt via FTP (using ftp username, upload to root directory). Certificate file contents: https://gist.github.com/jsopenrb/5873b20...d6b950151f
Code: device_id = 'DEV_TEST'
broker = 'DEV.azure-devices.net'
port = 8883
username = 'DEV.azure-devices.net/DEV_TEST'
password = 'SharedAccessSignature ...'
mqtt = require('mosquitto')
client = mqtt.new(device_id)
client.ON_CONNECT = function(...)
log('ON_CONNECT', ...)
client:publish('devices/' .. device_id .. '/messages/events/', '{id=456}')
end
client.ON_PUBLISH = function(...)
log('ON_PUBLISH', ...)
end
client.ON_LOG = function(...)
log('ON_LOG', ...)
end
client.ON_DISCONNECT = function(...)
log('ON_DISCONNECT', ...)
end
client:version_set(mqtt.PROTOCOL_V311)
client:tls_set('/home/ftp/azure.crt')
client:login_set(username, password)
client:connect(broker, port)
while true do
res, err, code = client:loop()
if not res then
log('loop error', res, err, code)
os.sleep(1)
end
end

Enable FTP server in System Config, then use ftp account and upload azure.crt to top level directory. Script has correct path set already.

You can save crt file via a script, run once.

You can help me with the information required to send data to iot hub de azure. I'm using a logicmachine5 reactor to monitor variables related to electrical energy, I need to send and monitor them in the cloud.
Thank you

Here'se a scheduled script that forms a JSON-encoded string with object values and then pushes them to Azure, then disconnects:
Code: require('json')
data = json.encode({
obj1 = grp.getvalue('32/1/1'),
obj2 = grp.getvalue('32/1/2'),
})
device_id = 'DEV_TEST'
broker = 'DEV.azure-devices.net'
port = 8883
username = 'DEV.azure-devices.net/DEV_TEST'
password = 'SharedAccessSignature ...'
mqtt = require('mosquitto')
client = mqtt.new(device_id)
running = true
client.ON_CONNECT = function(stat, code, err)
if stat then
client:publish('devices/' .. device_id .. '/messages/events/', data)
else
log('mqtt connect error', err, code)
end
client:disconnect()
running = false
end
client:version_set(mqtt.PROTOCOL_V311)
client:tls_set('/home/ftp/azure.crt')
client:login_set(username, password)
res, err = client:connect(broker, port)
if not res then
log('mqtt initial connect error', err)
running = false
end
if res then
while running do
res, err, code = client:loop()
if not res then
if running then
log('mqtt loop error', err, code)
end
break
end
end

log('mqtt connection failed', err)

You need specify correct device_id, broker, username and password parameters. Follow this guide: https://docs.microsoft.com/en-us/azure/i...tt-support

Hi,
I'm having trouble to connect to IoTCentral too. Is it possible to use this to IoTCentral or just with IoTHub?

Duvan2127 has contacted Microsoft support in this matter. Here is a reply from MS. Maybe Duvan2127 can provide further comments or tests done for this?
Step 1 : Get Connection string from the tool. It will give to Hub name
Example
C:\Users\anhashia\AppData\Roaming\npm\node_modules\dps-keygen\bin\windows>dps_cstr 0ne000475B9 mydevice ********************
...
Registration Information received from service: iotc-3d8d214e-281d-454a-9c7d-259fd8bb49ed.azure-devices.net!
Connection String:
