Can't connect to micro:bit via BLE and now not receiving data

MIT App Inventor Help
1

Hello,
I'm trying to connect a micro:bit v2 to App Inventor via BLE in order to receive data (numbers).
Scanning for BLE devices works fine, and the micro:bit shows up in the list, but when I try to connect, I keep getting an error.

I tested with other BLE devices, and they connect and work without any issue.

Also, the micro:bit connects normally when I test with the nRF Connect app, so I don't think there's a problem with the micro:bit hardware either.

I've attached the .aia project file for reference.
Any help would be greatly appreciated!
Thanks in advance.

Are you using the latest BLE extension, from 20240822?

Hi, Peter.
Yes, I am using BLE extension from 20240822.

The error says the UUID string is too large

Looking at the contents of your AIA file, it looks like you are using Version 20200828.

Nice

Hi, ewpatton.
I downloaded the latest version from the official website, and the filename includes "20240822", so I believe it's up to date.
Would using a different version possibly fix the issue?

Hi, ABG.
I did not specify any UUIDs, the same error keeps occurring.

Oh, I must have uploaded the wrong file by mistake.
Thank you, Peter. The connection issue is now resolved.
However, the data values are not appearing.
Could you please help me with that?
The data is in the format 'Sn: nnn' (e.g., 'S1: 570').

Data not received from BLE-connected device

I’m trying to receive data from a micro:bit v2 via BLE..
Although the micro:bit successfully connects, the data does not appear on the screen.
The data is in the format “Sn: nnn” (e.g., “S1: 570”).
Any help would be very much appreciated.
