Extend battery life by connecting intermittently

Thank you for your insight! I'm looking at the NRF class in the reference now thanks to your replies.

EDIT:

After reading about NRF.setConnectionInterval it seems much of the idea here can be achieved in a bangle app by some combination of:

• the bangle scheduling library
  
• NRF.setConnectionInterval (max 4000 ms)
  
• NRF.sleep() + NRF.wake() (to go beyond 4000 ms interval)
