HM-10 doesn't work with AI2

So I don't exactly know if this is the right place to ask this, but I've tried multiple places and havent gotten any responses as of yet.

So I currently have an arduino UNO set up with a HM-10 module.

I'm using the setup seen at 0:13 of BT05 HM-10 AT Command - YouTube and I'm using the app inventor "code" of 9:38 of HM-10 BLE Android App using HM10 & AI2 only. NO ARDUINO - YouTube.

My phone can see the Ble module in the bluetooth section (although it can't connect to it, it says it needs an app to do that) and I can connect to it via the BLE scanner app. but when I open the app, nothing shows up.

The firmware is DSD TECH V551.

Any help would be greatly apreciated.

I suggest you read Martyn Currey’s excellent tutorial. HM-10 Bluetooth 4 BLE Modules | Martyn Currey

The first link is about configuring Bluetooth, not communicating with an app. The wiring therein should be OK though. You only need power to Bluetooth in order for phone to see or connect, Seeing does not mean the serial wiring is kosher, so check it again - Tx>Rx and Rx<Tx. A phone that is not BLE compatible can still see a BLE device. Ditch the app inventor stuff and download a terminal app that is is specifically for BLE.
