<![CDATA[Help with M5Stack CoreS3 BLE Implementation in UIFlow 2 - Detecting Specific Beacon]]>Hi everyone,

I'm really struggling with BLE implementation in UIFlow 2 and could use some advice. Here's what I'm trying to accomplish:

Goal:

  • Continuously scan for Bluetooth devices
  • React when a specific BLE beacon appears (e.g., change the screen color to white)

What I've achieved so far:

  • Successfully scanning for devices
  • Retrieving the RSSI (signal strength) of discovered devices

Current issues:

  • Unable to display the names of the discovered devices
  • Not sure how to detect a specific beacon and trigger an action

I've been working on this for days now and I'm stuck. Can someone please provide some guidance? Here are some specific questions:

  1. How can I display the names of discovered BLE devices?
  2. What's the best way to identify a specific BLE beacon among the scanned devices?
  3. How can I trigger an action (like changing screen color) when the specific beacon is detected?

Any help, code examples, or resources would be greatly appreciated. Thank you in advance!

I know it has been a long time since you posted this, and I am curious if you ever got it to work. While I have worked with M5Stack (Blockly) for years. I know I can help you with the other aspects of your desired application and am more than willing to assist. This however is my first experience with BLE device scanning.

I copied your code into my CoreS3 with UIFLOW2 V2.2.4, and I can't even replicate what you have done.

I would very much appreciate an update on your experience.

Thank you

Bruce Kusens

I can't detect any with Atom Lite.

I'm interested in the project, I'm trying to make it so that when it detects a BLE MAC it turns on a light
