I've been experimenting using CBEACON to send the output from a python file (at present this is simply text saying "test").? The beacon triggers ok and seems to contain the required text content but I see an error in Direwolf - "Unknown APRS Data Type Indicator "A",..."? ?

I see from the APRS101 that types of A-S are marked as "do not use".? ?I'm wondering if this is an issue with my script, or is it the way CBEACON is set up?? ?For info, my CBEACON reads as follows - CBEACON sendto=0 delay=1 every=0:30 via=WIDE1-1 infocmd="/usr/local/bin/test.py"

Thanks

Regarding the OP’s question. I’ll attempt it.
“Does anyone know if Direwolf supports kiss over BLE or if it's in development?”
Finding a Bluetooth stack (lets go with BLE—since that seems to be universal and the future for the BT SIG) for applications that run on say a Raspberry Pi (that DireWolf can use) has always been a problem. I’ve never seen a BlueZ implementation that was usable.
For phones—there are several: Core Bluetooth (iOS), BlueDroid (Android and ESP32).?
NimBLE for microcontrollers.?But none for Linux on RPi. Except BlueZ.

I’ve seen python apps on rPi that use BLE. And apps using dongles like BleuIO.?
I’ve heard that “Qt has Bluetooth Low Energy support as host since Qt 5.7.?. It is available under LGPLv3 or commercial license, and exposes a C++ API”. But I’ve never seen it used.
I’m an iOS dev so I might not be up-to-date on BLE for Linux but that seems to be the problem. A BLE stack that can be easily integrated with DireWolf. An expert on Linux might want to set me straight. That would be appreciated.

Sorry if you find bold font "abusive".?
I am not sure of any other way of emphasis (which in itself is not meant to be offensive).
In many screen settings, italic does not show well (at least on my screen), so I almost always use bold with italic (so it can be seen).
If I were to use all caps and bold - that would be different.

More BLE info

HC-02

Cable Replacement?

Edit: Do not use these BLE Characteristics. Use the Mobilinkd “standard”

?

It could be the?

HC-02 Bluetooth 4.0 BLE Slave Module to UART Transceiver for Arduino Compatible with Android and iOS

I wasn’t precise so maybe I did deserve all that Bold font abuse.

Well the HG-UV98 has an app that runs on the iPhone.?

The iPhone only allows apps in User-Space (BLE) not System Space (Bluetooth Classic) unless they are type accepted in their expensive qual program.

The HG-UV98?has an HC-NN variant. I know this to be true because i opened my HG-UV98 up and looked inside. It looks much like the HC-05 module. I doubt the they went through qual.

The danger is the it becomes the “De Facto” standard. I left off the Latin because I didn’t want to show off.

That link didn’t work for me. Maybe because it was across two lines. And my iPad didn’t like that.?This did:?

I filed an issues against the spec to include an optional?BLE characteristic for wireless PTT.
Rob derives PTT from the audio for his Mobilinkd I think.?
A complete wireless interface (with a TNC/modem) and a radio would also include wireless PTT, IMHO.?

There is sort of a BLE serial interface “standard” based on the HC-05

Do not use this one! Please.?One amateur data radio in production uses it. Instead, use the Hessu/Mobilinkd BLE interface.
We really only need one standard. IMO

thanks for the clarification for everyone and the great explanation.

This is the related work done to make the Mobilinkd work over BLE that i could find
nice to know that i'm not the only one looking forward to this.
I'll keep a lookout for your app

will direwolf support ? as a wildcard for one letter(s) or does it only do *?

if i filtered EAX??? would it work?

Hi Rob,
thanks for the reply
apris.fi app on iOS trying to make a ble kiss connection using a rasp pi 4 and latest dev of direwolf

Thanks,

Hi Robert,
I have configured Direwolf in the past to use Bluetooth-Kiss-TNC using APRSDroid,
what i would like to do is connect using APRS.FI on a iOS device.
I have gotten the TNC to work over TCP but I would like it to work over BLE for mobile applications when no network is around

Thanks,

Does anyone know if Direwolf supports kiss over BLE or if it's in development?


Thanks,

Thanks Rob, that sounds like my next project!? :-)

Anyone that's been around for a while remembers the iMic, basically a USB audio interface or if you wish USB sound card. I have direwolf running on my M1 MacBook Air with a SignaLink USB but would like to try using the iMic instead.

I've connected the iMic input to the speaker output of my radio, and in my direwolf config file I set ADEVICE0 \u201ciMic USB audio system:1,0?\u201d, which worked when I connected it to a Raspberry Pi.?
So the question is how do I define ADEVICE in the config file to us the Apple iMic on my laptop?

Very nice!
You could use the internal Direwolf script capability to alter/add a comment and send the "opening announcement" over the air.
Even better would be to use the script to determine if the opening is somewhat directional (example NE, N, and NW are open to > 100 miles).
I believe the Direwolf-APRS-Toolkit.? I believe the format would be something like:
CBEACON delay=0:15 every=0:10 via=WIDE2-1 commendcmd=" `PYTHONPATH=~/{pathtoscript}/{script}.py`"

NOTE:? Since Direwolf is already handling the timing (delay and every), you won't need the CRON job anymore.? The same script would create and send the email (if you choose) and post a comment on the air to inform others of the opening.

I know of one station locally that did this for some time.? I don't know if they did it through Direwolf, some other client, or manually.
I also don't know if they are still doing it.? I haven't seen a "band opening" message in quite some time.
