Can't connect to Nano with DVR8825HW203_329 firmware

I built a MYFP2_ULN2003 V280 back about 2019 using the stripboard method and it's been working great since then. I got a new scope and that little stepper motor wasn't going to cut it so I've built a new focuser after having boards made (DRV8825-HW203 M-MT-F-BT). I've gone through the configuration and the only things I have defined in focuserconfig.h are the DRV8825HW203 and bluetooth. I get no errors when uploading to the Nano, however I can't connect to it using the MYFP2PRO windows app V 2.4.3.0. It fails to connect, then in the Status Messages section it says "Serial Port is already connected. Please click Disconnect first, then click Refresh". This is after rebooting the PC and reconnecting the focuser USB. When I close the focuser windows it doesn't warn me that the serial port is connected so that seems odd. I can connect to the bluetooth but it doesn't respond to commands or get the focuser information such as position. I updated to the latest version of the windows app and now I get an error saying "Serial Port Failed to Connect". When I click the connect button the L LED on the nano flashes, then the RX LED flashes quickly a second later.
I have the Nano mounted to the board with header sockets so I pulled it out, put it in a breadboard and tried out a blinking LED sketch and it worked. I cleared the eeprom, reloaded the DRV8825 firmware and still no connection. Here's where it gets weird - I loaded the old ULN2003 sketch and it connected using the windows app. So I'm assuming I have a problem with the DRV8825 sketch, but I haven't made any changes other than those two defines.
I have two Nanos and 2 PCs and it behaves the same way with any combination of PCs and Nanos, on the circuit board or the breadboard.
Any advice would be greatly appreciated.
The latest frimware 330 should work with Windows 2511
Older firmware will not work with 2511
Depending on the firmware version you used to program the controller, win 2430 probably will not work.
I do not offer any help on old versions. Its explained in the pdf. Do not try bluetooth until the focuser is running trouble free with ASCOM or Windows
I offer the following advice
1. reprogram using firmware 330 using Arduio IDE.
2. Open serial port monitor within the Arduino IDE, set speed to 9600
3. Type :00# and send it to the serial port
4. The controller should respond with Pxxxx# which means Position xxxx
5. Exit Arduino IDE
6. Remove old windows app using control panel
7. Install windows app 2511 and remember where you specified the folder where the log files will be created
8. Connect controller to computer/usb port
9. Select the Com port and correct speed in the Windows app
10. On the Logging tab enable logging for Messages (make sure the checkbox is checked)
11. Click the Connect button
12. If it fails tto connect
13. Close Windows app
14. Goto the folder where the logfiles are stored (7 above) and send me the myFP2WLog-xxxxx.txt file

I saw V 330 is out. Loading that version allowed me to connect. The motor won't turn but it's progress none the less.
ASCOM 330 is broken.
Sorry but you just need to have some patience before it gets fixed
ASCOM 290 works.
Firmware 330 should be ok
Win 2511 should be ok

Yes firmware 330 fixed the issues, everything is working as it should. Thank you Robert. I didn't realize there was an ASCOM 330. The challenge now is fitting everything into the project box.
The ASCOM update 33x is still being tested. It is a rather large update so its taking time to clear all the various tests with different focuser types and options.
