[DanaKit] Progress update 04-08-2024

[bastiaanv]

A long overdue update of DanaKit containing the following:

• Resync Trio dev to dana branch
• Updated localizedTitle for better stats reporting on open-iaps.app or similar (replaces the Dana-i/RS with the actual device name)
• Full rework of the BLE layer -> Includes the support of Continuos BLE mode (docs see: https://loopkit.github.io/loopdocs/troubleshooting/dana-heartbeat/#continuous-bluetooth-mode)

Status

Success as far as running with a simulator goes.

Configuration

• Build latest version from batiaanv Trio feat/dana branch, commit c12a6f11
• iPhone 8 running iOS 16.7.9
• updated dana-simulator to latest commit, e144cbe
• add Dana to phone using rPi4 running dana simulator
• use Nightscout as CGM source

First attachment of simulator to phone

This test report is for @bastiaanv - I routinely need to add the pump simulator and then remove it and add it back before I can get a green loop

• Connect phone to rPi simulator
  • Trio sent TB of 0 for 60 min at 8:21
  • CGM comes in at 8:20, 8:25, yellow loop
  • pump screen says last sync was 8:26
  • CGM comes in at 8:30, shows looping, pump error failed to make connection, red loop
  • pump screen says last sync was 8:31
  • probably a simulator issue

Test with phone unlocked, app in foreground

• Delete and reconnect to rPi simulator - try again
  • green loop at 8:35
  • green loop at 8:50

Test with phone unlocked, app in background

• open app and check status at 9:05
• red loop with immediate reconnection and green loop

Pretty sure that's all the testing that can be done with a simulator for Dana.

@marionbarker Thanks for checking dev! I fixed the submodule.

About your test setup, did you enable the continuous mode? Did you see a status connected? https://loopkit.github.io/loopdocs/troubleshooting/dana-heartbeat/#how-to-enable-continuous-bluetooth-mode

Status

I must still be missing something The continuous mode (with a simulator) is not working

"Bug?" Report

The CAGE did not update for NS when new Dana was added

Test with Continuous Mode

I followed the directions from this comment and turned on Continuous Mode.

• The Status shows up with Connected and green dot
• Added carbs and turned on a glucose pattern upload to NS (from my Mac)
• Phone (SE, iOS 17) is configured for closed loop and has a green loop
• Use NS as CGM and upload treatments to same site

Test in Foreground

• went straight to background test, had some issues but thought it may have been my set up
• Quit and restart and get a green loop while in foreground
• leave app in foreground to make sure it keeps looping - it does

Test in Background

• put the Trio app in the background at 12:17 (local) with phone remaining unlocked
• monitor via Nightscout to see if looping continues
  • NS shows stale at 12:58, 39 m ago since last loop
  • open app - it shows signal loss on pump then immediately reconnects
  • but doesn't loop
• quit and restart app, press on loop icon and it loops and now have green loop with NS updated

Test with phone locked

• lock the phone at 13:03
• NS site shows phone is not looping

More comments

When I first put app in background while phone was connected to Xcode, I noticed that this message happened about every 2 or 3 seconds.

NotificationHelper.swift - addRequest(identifier:content:triggerAfter:deleteOld:)#79: sending com.bastiaanv.continuous-ble.disconnect-warning notification

followed by a bunch of conect to pump messages but no determineBasal was happening

Rebuild to phone and watch for that. Get one and only one message at 13:12:31 But this message is going through every second

ContinousBluetoothManager.swift - keepConnectionAlive()#57: Sending keep alive message

Put app into background at 13:18 (those keepConnectionAlive messages stop and the disconnect-warning notification messages begin - every 2 sec).

NS shows stale loop. Log attached: Trio-feat-dana-continuous-background-Xcode-log.txt
