Android Question Do I need the adafruit libraries to use adafruit.io.

[Lee Ingram]

I have an adafruit.io account and a cloudmqtt account. The connect parameters are different. I'm not sure how to connect to adafruit.io

Thank you, Lee

What is adafruit.io?

 

[Lee Ingram]

adafruit.io is adafruit's MQTT broker.

https://io.adafruit.com

I been able to successfully connect to clouldMQTT but I have not been able to connect successfully to adafruit.io.
With B4J I can connect but I am not been able to publish or subscribe. Adafruit has a nice platform for debugging and testing topics and payloads.
Thank you,Lee

I have also been able to connect using Arduino IDE, but not using B4R.
I really want to just use B4X products

I'm able to connect with this code:

Sub Activity_Create(FirstTime As Boolean)
   If FirstTime Then
     mqtt.Initialize("mqtt", "tcp://io.adafruit.com:1883", "b4a")
     Dim mo As MqttConnectOptions
     mo.Initialize("user", "ccccccccccccccc840e")
     mqtt.Connect
   End If
End Sub

Sub MQTT_Connected (Success As Boolean)
   Log(Success) 
End Sub

Thank you for the helped. Adafruit.io is pretty awesome, and so is B4X.
It was a bit tricky to publish/subscribe. The below code was very helpful to my success.
Thank you for the snip-it also.
Shalom, Lee

Dim s As String = "abcde"
Dim bytes() As Byte = s.GetBytes("UTF8")
'and back
s = BytesToString(bytes, 0, bytes.Length, "UTF8")
