I’m new here. I would like to get value from my device light sensor that on the mbed pelion cloud. Can anyone point me to good tutorial on setting notification callback on C# or VB.net?
https://os.mbed.com/docs/v5.8/reference/callback.html can be of help
Thanks for the link, but I think I didn’t explain what I want to do. I would like to develop web application to read the sensor value from the mbed pelion cloud. I already have device connected to mbed pelion cloud. Below some of my codes so far…
Dim url As String url = "" If param = "resource" Then 'GET method - list of resources url = "https://api.us-east-1.mbedcloud.com/v2/endpoints/xxxxx" ElseIf param = "subscriptions" Then 'subscriptions url = "https://api.us-east-1.mbedcloud.com/v2/subscriptions/xxxxx" ElseIf param = "responseID" Then 'POST method - async-response-id url = "https://api.us-east-1.mbedcloud.com/v2/endpoints/xxxxx/3200/0/5501" ElseIf param = "events" Then 'GET method 'List all device events url = "https://api.us-east-1.mbedcloud.com/v3/device-events/" ElseIf param = "devices" Then 'list all devices url = "https://api.us-east-1.mbedcloud.com/v3/devices/" ElseIf param = "eventID" Then 'device event id url = "https://api.us-east-1.mbedcloud.com/v3/device-events/xxxxx" End If Dim req As HttpWebRequest = TryCast(WebRequest.Create(url), HttpWebRequest) req.Headers.Add("Authorization", "Bearer API Key") req.Method = "GET" req.KeepAlive = True req.ContentType = "application/json; charset=UTF-8" req.Accept = "application/json" If req.Proxy IsNot Nothing Then req.Proxy.Credentials = CredentialCache.DefaultCredentials End If Dim dataStream As System.IO.Stream Dim res As WebResponse = req.GetResponse() dataStream = res.GetResponseStream() Dim reader As New System.IO.StreamReader(dataStream) Dim responseFromServer As String = reader.ReadToEnd() Return responseFromServer reader.Close() dataStream.Close() res.Close()
There are actually some SDKs (one in C#) which should help you doing what you want:
For C# examples, please have a look at corresponding repository.
Hope this helps,
