Purpose:

Modify the eager-connect method for Bluetooth communication with Pods:

• This modification affects the handling of iPhone 16/17e with Atlas Pods when the app is in the background or the phone locked; other iPhone/Pod combinations are not affected
  • Before this change, the program manager was essentially keeping the 16/17e+Atlas Pod Bluetooth in a keep-connected mode
  • After this change, the program manager allows the Bluetooth connection to close once messages are completed just like it does for other iPhone / Pod combinations

Background

The Bluetooth connection method for Pods has undergone several revisions driven by both the increased incidence of 203 Faults for Atlas DASH Pods and the very slow connection for iPhone 16/17e with Atlas Pods.

Loop Release v3.14.7 used the first modification from keep-connected to ble-heartbeat and was associated with a reduction in 203 Faults but did not provide relief for slow Bluetooth connection for users of iPhone 16/17e with Atlas Pods.

Loop Release v3.14.8 and v3.14.9 used the second modification of eager-connect which did provide relief for slow Bluetooth connection for users of iPhone 16/17e with Atlas Pods, however, these implementations essentially kept the 16/17e+Atlas combination always connected to Bluetooth

• We got several reports of the return of 203 Faults for users who updated from v3.14.7 to .8 or .9 for users of iPhone 16/17e with Atlas Pods
• Using those Loop Reports, the modification to the OmnipodKit pump manager was proposed and tested; and is now ready for wider testing in the Loop dev branch (v3.14.10).

This update should provide the improvements for all iPhones and all Pod Types.
