- Nov 24 7:58 AM
Disregard part about not being able to update/save user’s edits --- I re-downloaded the HTML/files and installed over the existing one – now I can save user’s details … What happened there I have no idea – maybe I mixed up HTML folders ????????
Whats the latest RPiBPQ available ???
Ah thanks for that tip John – will do that …
I have downloaded RPiBPQ and HTML folder/files from your site .. All installed and am using the config file from my desktop LinBPQ .. I notice that RPiBPQ is version 22.214.171.124 – I thought it was higher (like my desktop LinBPQ) …
I started up RPiBPQ and started configuration under the Web Page … I can configure everything but I can’t add users – by that I mean, I can add a user and edit the detail but it won’t save ???? .. I’m sure my file permis sions are OK ..
You'd need to enable the APRS code in LinBPQ for bridging to work, but so long as you define the ports as receive only and don't configure the Igate it won't do anything.
OK John, I understand the bridging commands – it makes sense ..
As I’m not using the APRS server in LinBPQ will the ‘bridge’ commands still hold ???
For instance, I create the socat Com ports and then use the slave on APRX and the master Com port on BPQ, then use the bridge commands – will that work to bi-directionally link APRX and BPQ ??

Oops – look like I’m starting to g et confused …. I’m thinking in terms of IP-tunnels etc. and assumed TCP was the format used …
John what ‘method’ are you suggesting ?? .. Are you referring to your doc on DXSpider linking to BPQ ???
The socat pair is a pair of com ports - nothing to do with TCP.
For DX Spider, the method I suggests cre ates a KISS link between LinBPQ and the Kernal ax.25 , and runs NETROM over it, so the spider node appears in the LinBPQ NODES table, and can be connected to like any other application.
For APRX you need UI frames, and direct access to the radio ports. Though you could do something similar to the Spider setup, APRX would have to digi through LinBPQ to get to the radios. By using the method I suggest, frames are passed unc hanged between the radio ports and APRX using LinBPQ's bridging option.
Hmmm John, sort of defeats the purpose of what I’m trying to do …
My understanding of your doc of linking DXSpider to BPQ is that it is a TCP link by virtue of the socat pair, so why can’t I link APRX to BPQ using APRX’s 3rd method (TCP) and another socat pair ??
Usually I just figure out what I want to do then try it & #8211; if it doesn’t work, I figure out something else and try that, ad nauseam – until I get it to work (called empirical design - *Grin) …
In this instance, I’m tired and I’m ‘taking shortcuts’ – had a few consecutive sleepless nights working here and I think it’s showing - *Sigh …
I don't think you can use the same COM port for both LinBPQ and the Kernal ax.25. So I think you'll have to use a Serial Device (in this case half of a socat pair) for APRX.
This assumes you are using the same radio port for APRS and normal packet traffic. In most p laces dedicated frequencies are used for APRS, so you could define the APRS port to APRX and the general packet port to LinBPQ, but I don't think that applies to you.
Thanks for the reply John …. From what I’ve read of BPQ, I had this vague idea of what you just mentioned about using BPQ to control the radios and interface other services ..
APRX from what I understand has three methods of talking to radios:
1.Linux AX.25 devices (ax25-device); 2.Generic POSIX serial ports (serial-device); 3.Remote network serial ports (tcp-device)
Sinc e I need AX25 utilities for BPQ/DXSpider &nb sp;I’ll use ‘1. AX25 devices’ to get APRX to talk to the radios … I wonder if by virtue of using the AX25 utilities for APRX, I’ll be able t o ge t BPQ and APRX to talk to each other ?? ..
Would I use a similar technique to get BPQ and APRX linked as in BPQ and DXSpider ??

LinBPQ is desgined to be a replacement for the Kernel ax.25 and Netrom code, not to use it. There are probably ways round this, but I'd suggest letting LinBPQ control your radios.
As far as I know, you will still need the Kernel ax.25 for Spider - as you've mentioned, there are instrructions in my docs.
I believe APRX talks directly to the TNCs and doesn't use t he Kernel ax.25, There is a section on using other APRS clients with LinBPQ in the document
Bob, thanks for responding - sorry for the delay in re plying – been busy cleaning up (tweaking) the various services I have added to the Raspberry Pi …. Currently I have APRX (APRS server) and DX-Spider running on the RPi … RPiLinBPQ is installed and partially configured but disabled until I can clarify the way to go – see below ……..
You say, let the AX25 utilities control the radios and then let services that require the radio(s) work via the AX25 utilities .. Can BPQ work via the AX25 utilities to get to the radios ? ??
Can one not swap this idea around and let RPiLinBPQ control the radios (radios connected to BPQ) and then services that require using the radios, work via RPiL inBPQ instead ??? .. Is the mechanism available in BPQ to do this ??? .. Looking at the scenario I see that BPQ is the ‘main’ feature here with other serv ic es being accessed via BPQ (or if running in the background (like APRX/DXSpider) then BPQ allows them access to the radios) …
Bottom line - which would the least messiest (most effici ent) way be to implement all this ???

You can let t he ax25 utilities control the com port but also let another packet program like BPQ access the radio port at the same time.
net2kiss can echo traffic from/to an existing ax25 interface. (Example: net2kiss -i ax0 /dev/ptys8)
You attach the tty slave to BPQ (in this example, ttys8)
Now both "see" the radio inter face.

I’v e fitted a radio/TNC to USB port ‘/dev/ttyUSB0’ (USB to RS-232 cable) via a powered USB hub and using minicom on the RPi I can ‘talk’ to the TNC/Radio combination perfectly - (TNC’s being PK-232 (HF) and MFJ-1270B (VHF)) …
I am contemplating running AX25/Netrom so that various apps can access the radio USB ports, like BPQ, DX-Spider, APRX (I kno w BPQ has APRS feature but I don’t like it) … John has a web page showing how to run DX-Spider through BPQ …
Would using the linux kernel AX25 and Netrom code be the way to go or should I let BPQ control the com ports (USB) and then attach other apps through BPQ – can I use BPQ to ‘control’ things and if so, how ???
