Hi,

By right watch dog command should not be sent if message is being sent. We need to further check on what happened here.

Meanwhile, you may want to disable the watch dog or set the interval to a bigger value.

Thanks

I cannot disable watchdog as it's the only elegant way to handle the modem being disconnected somehow. If I increase the w/d interval there is still the chance a message and w/d check occurs concurrently so the problem will persist.

Try to power down the modem or disconnect the serial cable and then send a message and an I handled exception occurs, so watchdog is essential to a good user experience.

Hi,

Can you show me how to send the message? By right when a command is being sent to the device, another command should be blocking until the previous command completed, provided both are on the same thread.

Thanks

Hi, after a lot more testing, it seems this is not the watchdog message. See the attache dlog where the error occurs independently of the watchdog message:

This is an ongoing issue and I could really use some support. Here's the code I'm using to send the SMS.

 Public Function SendSMS(phoneNumber As String, message As String, ucs2Encoding As Boolean, flash As Boolean) As Integer
   Dim msg As Sms = Sms.NewInstance
        Try
            msg.Flash = flash
            msg.DestinationAddress = phoneNumber
            msg.LongMessageOption = MessageSplitOption.Concatenate
            msg.Content = message
            If ucs2Encoding Then
                msg.DataCodingScheme = MessageDataCodingScheme.Ucs2
            End If
            res = ModemGateway.SendToQueue(msg)
            If res Then
                _log.Debug("Queued " + IIf(flash, "a flash", "an") + " SMS [ID: {2}] to {0} with content:  {1}", phoneNumber, message, msg.Identifier)
            Else
                _log.Error("Plugin error sending SMS: " + ModemGateway.LastError.ToString)
                Return -1
            End If
        Catch ex As Exception
            _log.Error(ex, "Error trying to send SMS to: " & phoneNumber & " : " & ex.Message)
            Return -1
        End Try
        Return 0
End Function

Hi,

Can you let me know

1. What is the model of your modem?
2. How many COM ports you see for this devices?

Thanks
