Re: Bluetooth GPS Receivers
I was able to Roll Back WIN 11 to WIN 10. Found an older Prolific driver for the GPS-5 Receiver that used to work and load that. I have APRSIS32 working as advertised on my Windows tablet again.
?? So much for progress. I? could not get the Garmin Glo 2 Bluetooth GPS Receiver to work. It would pair with the table, but not connect; never saw any streaming GPS data from it.

Make sure you go into settings and under connectors, usb/keying, usb send,? select RTS send.

Re: APRS-IS32 problem pobierania wst?pnego ca?ego regionu
I understand the task to be performed. Search and rescue of missing people is very similar to recovery of a high altitude balloon payload. Your total search area is somewhat defined, but the final search area is unknown.?
How is the APRS/OSM map detail used to locate the missing person? Are you using the map to be able to locate various resources, LKP (last known position), ICP (Incident Command Post), IPP (Initial Planning Point), for tracking the search teams, for defining search areas, and others?
You are probably not using the maps for physically discovering the missing person.
If you are searching an urban area such as this:
Here it is at zoom 17, and again at zoom 19. Zoom level 19 much more in detail, but it will take 16 times more storage space. I would argue that looking at the zoom level 19 maps will not help you find a lost individual any better than zoom level 17.
If we compare a rural wooded area like this:
at zoom level 17, versus zoom level 19. We once again don't see any more detail. There's no way to find a lost person under a tree in either map.?
However both zoom levels would be able to show a representation of where search teams may have travelled. You won't know every bush and rock that the search team looked at, but you will have a record of the area that they would have travelled through.
I'm not trying to tell you how you need to run your operations, but rather just trying to ensure that you are not wasting a lot of time and resources downloading a huge amount of data that provides very little added value.
As a further suggestion, have you looked at other APRS clients for SAR use? APRSISCE/32 is not designed for real time tactical operations such as SAR. It does not have a lot of capabilities that would be handy to have for SAR operations.
Xastir was the first APRS client that supported SAR activities, and had some tools built in that were useful for SAR work. Xastir can be a little strange to work with if you aren't familiar with it.
YAAC has some features that make it able to support SAR activities, and it is fairly easy to use.
SARTrack is specialized APRS tracking software that is specialized for Search and Rescue operations.? I have not used SARTrack myself, but am very impressed with the functional capabilities included in the software.?
SARTrack is probably the most complicated APRS tracking software out of the four programs we are talking about. I suspect that SARTrack requires a full time?dedicated operator sitting at the console to make use of all the functionality. It probably also will require the most effort to learn and understand its operation as it gathers the most detail about a SAR operation. If one is familiar with SAR operations, I would suspect that much of the functionality would be familiar to the operator, and they would just need to learn the buttons to press, and not have to learn the SOPs of SAR. Hopefully I have provided a little information that may be of use to you. In the end the amount data you download and how you use it are up to you. Just be aware that heavy use of the map servers may get you and or the application you are using banned for abuse.

In general, even 100GB is not a problem for me.
?
We help during the search for missing people in small villages, in fields and forests using APRS.
?
We follow the moving cavalcade, so we need the greatest possible approximation (the cavalcade is 100-200m wide).
?
We help throughout the Podkarpacie region, sometimes we go to action without even knowing where we are going (in many places there is no GSM and Internet). We learn about it in fact while driving with the fire brigade or the police.
?
That's why we need our entire region with the best possible magnification.

Re: APRS-IS32 entire region prefetch problem
Hmm, I missed the caveat on that site...
I thought it was just doing the calculation based on bounding box like you did in Excel. It says there's only 5.6 million tiles total for that area down to zoom level 18. You show 5.6 million tiles just for zoom level 18.
On the page that sent me to the tile estimator, they suggested each tile on average is 633 bytes.
Any way you count it, it's a lot of tiles, and a lot of storage space.

Let me answer my own question...
I just found a new toy!
You'll need 19 GB of file storage for all zoom levels down
to 18. I think you'll need another 48 GB of storage for zoom
level 19 if I can do math properly.
If you are using these offline maps for something like
ARHAB balloon recovery, or similar, you might find that the
extreme zoom level maps contain very little extra information
than the tiles a couple levels up. There are very few areas
where information on every blade of grass, and bit of gravel
are mapped.
The precision of the data in the OSM database is no where
good enough to have these extreme zoom levels provide much
useful information.
Maybe take some time to run through your process (whatever
it is you are trying to do offline), and have a look
specifically to see if the tightest zoom levels are actually
required.?
When I started playing with OSM I wanted similar offline
maps for the province of Alberta in Canada.
228 GB is a hefty chunk. I found that I really didn't need
anything?closer than zoom level 14.
Looking at your area, by the time you get to zoom level 15,
you already have house footprints, and just about all of the
information that can be seen. Zoom level 16 has bus stops, and
zoom level 17 puts addresses on houses. I'm not sure what more
information might be found on zoom 18 and 19. (I just found
some park benches and garbage cans at zoom level 19)
I guess there is an argument that can be made for needing
very tight zoom tiles, but generally very detailed work
doesn't happen on a large scale area all at once.?

The Enables/View Logs/Port(NMEA) screen shows that it is Enabled, just no data coming in. All the blocks on the lower line of Satellites are RED. Do I need to restart the program?

Re: Bluetooth GPS Receivers
First APRIS32 never transmits to aprs.fi.?? It only transmits to
the APRS-IS which in turn relays it to all interested clients, one
of which happens to be aprs.fi.
Second, do you have the proper passcode entered for your
callsign?
Third, what version of APRSIS32 are you running?? You can find
this in the About box.
Finally, if you bring up the Port(NMEA) trace log and enable it,
it may have some revealing information.

I tried a Globalsat BU-353N5 Receiver, since it uses an FTDI chip.
