APRS plugin (uiv32x visual basic)
Anyone help me!
How can i send telemetry data with this program uiv32x made by Visual Basic v5?
Private Sub mUIV_NotifyTelemetry(strCallsign As String, strTo As String, strDigis As String, strHeader As String, intSource As UIView32.FRAME_SOURCE, strTelemetry As String)
Dim strA As String
strA = strCallsign & ">" & strTo
If strDigis <> "" Then strA = strA & "," & strDigis
strA = strA & ":" & strTelemetry
ShowText txtStatus, strA & vbCrLf
i cant understand each variable!
Sorry about my English, 73 !
They aren't variables, they are strings.
I don't know much about the program you've mentioned, but the code snippet is building a string of text called strA from the other strings and adding a few characters to format it. If you were calling me, I think:
strCallsign = "PU5TOK"
strTo = "KK4AMP"
StrDigis = "Hello there!" (I think. someone else check me here if they know more about this particular program)
strA would be created as blank. The first line after the DIM for it would make strA become:
If strDigis was empty, strA would be unmodified by the next line. However, it isn't in this example so strA becomes:
PU5TOK>KK4AMP, Hello there!
strA then gets a colon ":" and telemetry added to the end of the line. Don't ask me about telemetry, 'cuz I dunno yet.
The last line of the subroutine appears to print the entire theng, then a CR/LF to be ready for the next print on a new line.

Are you using a TNC to send the APRS packets? Have you considered simply rolling your own APRS software, rather than relying on someone else's code?

Here's a page outlining the APRS protocol:

No I'm using only software

Thanks, I look
This was a great help, thanks
