I would be grateful for your feedback and comments.

Alex,

Here is what I used for my tests:

  1. ?I installed the new firmware version 1.25 on my AA-55.
  2. There is a new app for Android on the Google Play store (Dec. 4 update)? so I updated my version on my Android tablet.
  3. RigExpert posted a new version of AntScope 1.1.5 in the Files section of this group. I removed the old version and installed this program.
This is what I have found so far:

Good news
  • I transferred multiple 500 point sweeps and never had a single error. The app connects easily and does not freeze or lock up.??
Bad news
  • The? transfer time is now double what it used to be. Before it took 19 seconds for 500 points and now it takes 39 seconds. A 100 point sweep is about 8 seconds or so.
  • Terminating the android app in the middle of a sweep sometimes causes the AA-55 will "lock up" and no longer respond to keypad commands.? The only way to get it back is to remove and reinstall the batteries.?
Windows 8.1 PC

Good news
  • After connecting to the AA-55 I could now transfer 500 points without any errors and no spinning of the circle at the end.?
  • Continuous sweeping now works without data dropouts even for long 500 point transfers
Bad news
  • It? can take up to 8 seconds? sometimes to connect to the AA-55 and display that in the title bar.
  • The? transfer time is now double what it used to be. It? now it takes 45 seconds for a 500 point sweep. A 100 point sweep is about 9 seconds or so.
  • If you don't do a sweep within 10 seconds after connecting Antscope 2 to the AA-55 you cannot do a sweep.? The circle keeps spinning and nothing is transferred.? You? have to exit Antscope 2 and power off/power on the AA-55 to get it started again.?
  • The other thing I found is that the AA-55 screen is blanked out? during Bluetooth transfers.? I think this is done to save battery power. Unfortunately there is a new bug.? If you terminate Antscope 2 in the middle of? a sweep or you have a program crash the AA-55 Zoom sometimes lock ups and the keypad no longer works.? You have to take out the batteries to get it working again.
Other bugs
  • In the settings the selection of ITU region 1,2 or 3 is no longer there.? It is just a blank button that does nothing.
?
Summary
?
There are still some issues with the firmware as described above (slow transfers, lockup). AntScope 2 has some timing problems.? I have some experience in Bluetooth protocol analysis and have an idea why the transfer is slow and can share them with RigExpert if they are interested.?
