| 5 | +</head><body> |
| 6 | + <h1>Bangle.js 2 Button Fixer</h1> |
| 7 | + <p>Some Bangle.js 2 can get into a boot loop if their button becomes low resistance (due to water ingress or similar). |
| 8 | +This webpage attempts to connect to a Bangle.js 2 and uploads code that will enable something called 'lowResistanceFix' |
| 9 | +which causes the Bangle to do extra checks to ensure the button isn't pressed even if it is high resistance. The |
| 10 | +Bangle.js firmware must be at least 2v22 for this to work.</p> |
| 11 | + <p><b>Usage:</b> Click the button below, then when you see your Bangle appear in the list of devices that pops up, |
| 12 | +choose it and click 'Connect' immediately. If this fails, try and time your clicking of the 'Connect' button to exactly |
| 13 | +the point that the blocky bootloader text on the Bangle's screen disappears.</p> |
| 14 | + <p><button>Connect to Bangle</button></p> |
