#40502943 Filed 2017-01-23 Assigned Related CL 6798921 merged

Purpose

manual hardware sampler

Pending gatt.connect() should be cancelable

This page tests whether BluetoothRemoteGATTServer.disconnect() cancels a pending Web Bluetooth gatt.connect() attempt. The ESP32-C3 test device advertises as dino c(h)ancler.

Use this page over HTTPS. Web Bluetooth is not available from an insecure origin.

Live tester

Controls

First select the ESP32-C3 while it is advertising. Then make it unavailable and try canceling a pending connect.




Expected result



  
    
    
  1. gatt.connect() starts while the known device is unavailable.
    2. 
    
  2. Clicking Disconnect / cancel pending connect should make the pending promise reject promptly with AbortError.
    3. 
    
  3. After cancellation, requestDevice() and a connect attempt to another BLE device should still work without reloading the page.
    4.
