# I'm on a Call BLE Edition

* An Espruino [Puck.js](http://www.espruino.com/Puck.js) with red Neopixel and silicone lid is used to create a BLE button which lights up when you press the lid. This sits on my desk and I press it when I'm starting a phone/video call.

* When button/led is set on, it broadcasts 1 in BLE ManufacturerData

* When button/led is set off, it broadcasts 0 in BLE ManufacturerData

* A matching device on my home office door (either a [Pixl.js](http://www.espruino.com/Pixl.js) or ESP32 running [Espruino](https://espruino.com)) scans for those messages. 

* When it sees that the button is on, it scrolls a message on an attached [MAX7219](https://www.aliexpress.com/wholesale?catId=0&SearchText=MAX7219+) LED Matrix display

* My kids then know not to come barging in :-)

* A variation using a [Bangle.js](https://banglejs.com) is also included and is in the video
