Hello,

We will be documenting the Log functions in the next release - it will be updated within the documentation.

Glad that you have the temperature information going into Losant, this means that you have that side of things setup properly. And also good that you were able to update the device and mcStudio to the latest version.

I believe that you are using the GPS function and Log function:

if a GPS acquisition is ongoing, the log read has to wait for that to finish. Currently (this is changing when we do the warm start) both the logging and gps share a single SPI bus so they can't both happen at the same time.... This might lead to some less that elegant behaviours when debugging... for example if it takes too long for the GPS to finish mcStudio might stop and think the device is not responding...
The system will recover itself. So basically the execution of that line will be suspended until the gps acquisition is done.

Try loading the code directly into the device and see how everything works. It sounds like the issue you are having resides strictly within the debugging of the code and could be affected by what we mention above

Hope that helps,
Thanks

Hello,
There is a log function that is not yet described in our documentation. In an upcoming release, we will be releasing this information within the new documentation for mcStudio and the mcDemo205. That said, we do have some code that you can modify for your use to log information into the flash of the device. The below code is for an example using our partner, Losant, so you may want to modify this for your needs. The code is meant to log GPS coordinates and temperature and then, when in range of a gateway, you would press SW1 and the information would then be transferred to the Losant cloud to populate onto a map onto a dashboard.

here is the code and there are also some additional notes below:

Class gpsTracker
    Shared Locations As ListOfObject
    Const GPS_TIMEOUT_uS As Integer = 120000000 '120s
    'Const GPS_TIMEOUT_uS As Integer = 1000000 '1s
    Const GPS_MIN_SATS As Integer = 3 '3 sattelites minimum
    Const LosantDeviceID As String = "YOUR LOSANT DEVICE ID"
    Const LosantTopic As String = "losant/" + LosantDeviceID + "/state"
   
    Shared Event Boot()
        Locations = New ListOfObject()
    End Event
   
    Shared Event StartLocationAcquisition() RaiseEvent Every 7 Minutes
        Led2 = True
        Thread.Sleep(100000)
        Led2 = False
        Device.StartGPS(GPS_TIMEOUT_uS, GPS_MIN_SATS)
    End Event
   
    Shared Event LocationDelivery()
        Dim lat As Float = Device.GetLatitude()
        Dim lon As Float = Device.GetLongitude()
        Dim tmp As Float = TempSensor.GetTemp()
       
        If lat.IsNaN() Or lon.IsNaN() Then
        Else
            Dim entry As ListOfByte = New ListOfByte()
           
            entry.AddFloat(tmp)
            entry.AddFloat(lat)
            entry.AddFloat(lon)
           
            Log.Write(0, entry)
        End If
       
    End Event
   
    Shared Event SW1FallingEdge()
        Led3 = True
        Thread.Sleep(100000)
        Led3 = False
       
        Dim count As Integer = 0
        Dim offset As Integer = 0
        Dim lo As ListOfObject
       
        lo = Log.Read(offset)
        While lo <> Nothing
            Dim o As Object
           
            o = lo(0)
            offset = o.Cast(Integer)
           
            o = lo(1)
            Dim dtm As DateTime = o.Cast(DateTime)
           
            o = lo(2)
            Dim type As Integer = o.Cast(Integer)
           
            o = lo(3)
            Dim entry As ListOfByte = o.Cast(ListOfByte)
           
            Dim tmp As Float = entry.ExtractFloat(0)
            Dim lat As Float = entry.ExtractFloat(4)
            Dim lon As Float = entry.ExtractFloat(8)
           
            Dim jDate As Json = New Json()
            jDate.Add("$date", dtm)
           
            Dim jData As Json = New Json()
           
            jData.Add("temperature", tmp)
           
            Dim locStr As String = lat.ToString() + "," + lon.ToString()
            jData.Add("location", locStr)
           
            Dim jPayload As Json = New Json()
            jPayload.Add("time", jDate)
            jPayload.Add("data", jData)
           
            While Not Lplan.Publish2(LosantTopic, jPayload.ToListOfByte)
                Thread.Sleep(10000)
            End While
            count += 1
           
            If count = 30 Then
                Thread.Sleep(30000000)
                count = 0
            End If
           
            lo = Log.Read(offset)
        End While
    End Event
End Class

Additional notes -

1) you'll also want to add the temperature sensor library and the below GPS library if you want to use the code above with Losant:
Class GpsLocation
    Public Latitude As Float
    Public Longitude As Float
    Public Timestamp As DateTime
   
    Public Sub New(lat As Float, lon As Float, dtm As DateTime)
        Latitude = lat
        Longitude = lon
        Timestamp = dtm
    End Sub
End Class
2) I believe the flash will keep storing until you have enough data to start overwriting. If you do want to clear the flash, you can include or run the below function on a new script
Log.Erase()
3) if you are interested in working with the above code for a test, keep in mind that the device needs to be powered and in-range of an mcGateway for a suggested 30 minutes to ensure that the device grabs the time from the gateway. This is so that you can associated a time with the GPS coordinates

4) And, if you are going to use the above code and leave it unmodified to work with Losant, you'll notice at the end of the code that we have a time delay. This is due to how the Losant platform works which can only consumer a certain amount of data every 30 seconds. The time delay allows the device to send out a batch of data then wait and keep sending to ensure that Losant receives all the messages.

Hope that helps!

Can you post a screen shot of the device menu (showing your gateway IP) please?

Also, a screenshot of the error would help too

Thanks!

There were a couple of users that were discussing using Pi's as middle men - not sure the status of this.

Anyone out there that has done this that can help Bernstein?

As mcJohn mentioned, you can also forward the information to a service like CloudMQTT as an option. They do have a free tier and there are other ones out there as well. To help, you can check out this video that walks-through setting up CloudMQTT as a service. On this video we subscribe to the topic on an Android phone to view the data so not quite what you are looking to do but hopefully it helps a bit (CloudMQTT stuff starts around the 0:50 mark)

hmm, it is pretty straighforward. I find that the usual issue is information inserted into the wrong field and/or case sensitive mistakes.

Check out this video where we go through the whole process of setting up MQTT and sending information to an android client:

Hey Veleek,
Ok, thanks for the details.

I am sending you a note directly to get you details as we'll need to see your existing gateway back at our office to assess what the issue could be. Keep an eye on your email please

Have you been connecting to WIFI using WPS? If so, please try that again.

You can also enter your SSID and password into the gateway configuration when connected via Ethernet. This way, your gateway will always connect to your WIFI network.

This YouTube video should help you out too

let us know if that helps
Thanks
