Occasional scrambling of data on Bluetooth UART after automatic reconnects?

Thanks - interestingly that's:

• 13 carriage return
  
• 32 space
  
• 61 =
  
• 62 >
  
• 105 i
  
  

So not entirely random - > and = usually happen when a command has been sent to the Bangle without the starting \x10 character which tells it to 'be quiet' - so it's like if you were typing a command on the REPL in the IDE.

How big is the webpage you're requesting? It could be it's filled the input buffer for Bangle.js and there's been some kind of overflow - usually there should be flow control but maybe something happened for that connection and it wasn't working...

Also, just to check - are you running every 1 sec to try and stress test this, or is that what you expect to do normally? Doing one HTTP request a second is going to destroy your battery
