Re: How many clients can use one DireWolf instance?
Excellent. So how about the issue of one client crashing its entire computer (ex.: someone kicked the power cord out), so there is nothing to send "port closed" ICMP errors back to DireWolf on a different computer. Will DireWolf hang when the TCP window buffer for the failed client fills up because it blocks and can't advance to writing to the next client socket, or are these sockets configured non-blocking so a EWOULDBLOCK error would cause that client to be disconnected immediately? Presumably the default TCP window size is large enough compared to the typical AX.25 packet (with either KISS or AGWPE wrapping) that several minutes worth of packets on a saturated 1200-baud RF channel could be written to the kernel on a frozen socket before hitting the window size limit, so hopefully the TCP timeout would kick in before the socket window filled up. Or should I conduct the experiment myself and find out? :-) Andrew, KA2DDO ________________________________________ From: [email protected] < [email protected]> on behalf of WB2OSZ <wb2osz@...> Sent: Tuesday, September 28, 2021 5:55 PM To: [email protected]Subject: Re: [direwolf] How many clients can use one DireWolf instance?

I noticed the check is not as described exactly: ?? if data['outHumidity'] < 0 or 100 <=
data['outHumidity']:
That's < 0 (negative) or >= 100.
What I'd suggest (not a python coder either): ??? if data['outHumidity'] < 0:
????data['outHumidity'] = 0
? if 100 <
data['outHumidity']:
????data['outHumidity'] = 99
This would comply with the 2-digit humidity, and removes any negative values. ? If the values were negative, or actually zero, there would not be output because of the if statement before the file write.

Re: How many clients can use one DireWolf instance?
The network KISS and AGW interfaces can handle 3 simultaneous client connections each.
In extreme cases, where you need more, the limit can be increased by modifying a header file and rebuilding.
kiss_frame.h: #define MAX_NET_CLIENTS 3
If there is an error writing to a socket, the socket is closed, and becomes available to accept another client connection.
|
Re: How many clients can use one DireWolf instance?
According to the Direwolf manual (4.3 AGW TCPIP socket interface): ??? Dire Wolf provides a server function with the "AGW TCPIP Socket Interface" on port 8000. ??? Up to 3 different client applications can connect at the same time.
Section 4.5 KISS TNC emulation - network
?? I don't see a number of connections listed in this section. ?? HOWEVER, when I make a connection via KISS over TCP, I get the same kind of message:
????????Attached to KISS TCP client application 0...
????????Ready to accept KISS TCP client application 1 on port 8001 ...
So, it implies it can accept more than 1.

How many clients can use one DireWolf instance?

Further, are you running the latest 0.4 version of the plugin?
You may want to see this thread and switch your binding to "archive" in your weewx.conf file:
binding = archive

It seems the issue is getting Zeros for readings (maybe sampling too fast). The script could easily be modified to "not write" to wxnow.txt if certain value(s), which you know should always have valid data (say outside temp), report zero.
Since Direwolf 'always' sends the last line, not saving the zero line should fix your problem.
NOTE: if the "key sensor" is removed, you would have to change the check for zero to a different sensor.

I suggest you have weewx generate a wxnow.txt file, then have Direwolf send it as a comment in a position beacon, as stated in section 9.9.1 of the users guide.

Re: Interface documentation for programmers
If one is attaching at the kiss layer, then each client must be able to pack and unpack the packets and if the service is a connected services, handle retries.
Since APRS is essentially connectionless, this is not a major?lift.
If, however, one uses a connection based packet approach, then the clients must handle the retries for the packets and this can get complicated. ?
I have encountered?certain clients who do not handle the?retries well causing failure of the client.
Many/most of the low level packet software (AGWPE, Doundcard, Direwolf) do seem to handle the retries well.? Connecting the client over the AGW?layer removes the need for the client to handle the retries and for connected services and removes the need for the retry code at the client layer.
Although I see a lot of good in the AGW protocol, it does add an extra layer.
Why not just use KISS over TCP/IP. Then you are using the standard protocol for hardware TNCs. There is a lot of code (and even libraries) for the KISS protocol. The only differnece between getting data from a hardware TNC and a software TNC would be the source (TCP or COMM port).?
On Sunday, September 26, 2021, 09:57:19 AM EDT, Martin Cooper < kd6yam@...> wrote:
Xastir and other software uses AGWPE to talk to Direwolf. The protocol is fairly well defined. Implementing a client isn't trivial, but it's not super-hard either, as long as you're familiar with writing socket-related code. You also don't need to implement everything, if you don't need it all. (For example, if you only want to listen to APRS traffic, you don't need to implement the connection-based pieces.)
The spec is available in a couple of places. Here's one:
There is some example?code in C++ and Delphi (yes, really), but I didn't find it of much help. Working from the descriptive text, I wrote a full Python client that works against Direwolf, ldsped and AGWPE itself. Depending on what you want to do, you may also need code to work with AX.25 packets.
Direwolf can also talk via KISS, though that's more limited.
Hope that helps.

Re: Interface documentation for programmers
At the top of this conversation, you said:
"Although I see a lot of good in the AGW protocol, it does add an extra layer."
The point of my previous message was that there is an extra layer involved when using KISS that hadn't been mentioned. As you said yourself?below, you decoded packets received from Direwolf using KISS. What you got from KISS itself was just a blob of data; you had to implement some other specification to understand / interpret those blobs before you could do something meaningful with them. It is KISS plus that extra layer that is the parallel to AGWPE,?not KISS by itself.
I haven't claimed that there is anything you can do with AGWPE that you can't do with KISS plus that extra layer, or vice versa, nor have I claimed that one is better than the other. To each, his or her own. But let's understand that KISS by itself is just a blob transport, and there's more involved.
Martin. KD6YAM
So, with respect to the Direwolf interface, what in the AGW protocol is so much different? So far, there has been nothing I have done with the Direwolf AGW that I haven't done with Direwolf's KISS over TCP/IP. ?>>> On Sun, Sep 26, 2021 at 07:13 PM, John wrote: > I would

Using
KISS over TCP/IP, I have received packets from Direwolf, decoded those
packets, acted on those packets, and sent packets back to Direwolf for transmitting.? I have even help others use decoded KISS packets from Direwolf to aim satellite antennas at a balloon.
On Sun, Sep 26, 2021 at 22:14, Martin Cooper KISS by itself just provides an envelope and encoding for arbitrary data, and says nothing about what kind of data is inside that envelope. Encoding and decoding the data contained in a KISS packet is by agreement between client and server on what the packets contain. Without a higher level protocol / API that defines the contents, KISS has no concept?of, for example, enabling monitoring or opening a connection. So while KISS will help you get data back and forth, you still need something else on top of it. Even if there's a commonly understood agreement on the format of the contents, that's not part of KISS itself, but another layer. KISS plus that other layer may be equivalent to AGWPE, but not KISS by itself.
