ruuviTag won't connect to Espruino Web IDE

Try:

• going to this URL with your phone: https://www.espruino.com/ide/?code=NRF.setAdvertising({},{name:%22Espruino%20ruuvi%22});
  
• click the 'connect' icon in the top left and choose the Ruuvitag
  
• Once connected, click the 'upload' icon in the middle - it looks like a chip with an up arrow in it
  
• disconnect
  
  

Then hopefully the ruuvitag will be renamed and you can see if you can connect with the Mac
