If you can connect your CGM directly to *Loop* that is preferred. You can customize the *Loop* app to interface with the *xDrip4iOS* DIY CGM app if you prefer. You can use *xDrip4iOS* as a follower instead of a client to get some features from *xDrip4iOS* without any need to customize the *Loop* app.

If possible, it is recommended that *Libre* users take advantage of [LibreTransmitter](https://github.com/LoopKit/LibreTransmitter/blob/main/readme.md) which is incorporated into the *Loop* app for version 3.4 and later.

### Increase in DASH Faults

There have been a number of lots of Atlas DASH Pods that exhibit an increase in the frequency of certain DASH Faults when used with iOS Open-Source Automated Insulin Delivery Systems (OS-AID). This is different from the Bluetooth connection issues for some iPhone models: see [Keep Alive: Atlas or InPlay DASH Pods](#keep-alive-atlas-or-inplay-dash-pods).

To the best of our knowledge this is not something that we (as OS-AID developers and users) can control. People who have boxes that fail early find most Pods in that box fail early.

### Atlas or InPlay DASH pods
* The 203 fault is the most common one to exhibit an increase in frequency; occuring on the third day of Pod life
* The 016 fault also exhibits an increased frequency and this one happens early in Pod life
* You may be able to get Insulet to replace these, but there is no guarantee

We have looked at the analytics reported from Loop users who [share their data](../loop-3/onboarding.md#usage-data-sharing){: target="_blank" }. The increase in fault rate appears to go along with the increased used of Atlas Pods. Reports from users that their Pods failed early started in November/December of 2025 and continues to increase through at least May 2026. Note that 203 and 016 faults have been around for a long time. The increased fault rate (almost 20 times more likely for 203 and 4 times more likely for 016) is associated with the Atlas DASH Pods which use a different internal card with different firmware.

!!! warning "iPhone 16 (all models) and 17e model with Omnipod DASH"
**iPhone 16 all models** and **iPhone 17e model only** can be slow to reconnect to Atlas versions of DASH pods. This can cause delays to automatic and manual insulin dosing.
**iPhone 16 all models** and **iPhone 17e model only** can be slow to reconnect to Atlas versions of DASH Pods. This can cause delays to automatic and manual insulin dosing.

**Other phones, including iPhone 17 models other than 17e, work fine with InPlay DASH pods**
**Other phones, including iPhone 17 models other than 17e, do not have the reconnection problems with InPlay DASH Pods** - but see [Increase in DASH Faults](#increase-in-dash-fault) which affects all phone models and seems to be box specific.

Beginning in 2025, some of the DASH pods are produced with a newer version of chips and firmware. The only way to tell the difference before use is to examine the paper cover over the pods inside the box for the word `Atlas` (newer) or `SAW` (older) as shown in the graphic below. It is anticipated that `Atlas` pods, which report electronically as `InPlay BLE`, will become more common.

* The Atlas DASH pods, which advertise a Bluetooth Device name of `InPlay BLE` and indicate `-Atlas` in small print on the paper pod cover are fully compatible with all iPhone models except iPhone 16 and iPhone 17e

* Although `InPlay` Pods do work with the iPhone 16 and 17e you may notice some communication issues
* It can take many attempts to get the pod to initially connect when pairing; just keep hitting retry
* Once the pod disconnects itself from the phone Bluetooth, the phone is slow to reconnect the pod to the *Loop* app
* Pod firmware initiates the disconnect 3 minutes after the last message exchange
* With other models, the reconnect happens in about 1 sec
* With iPhone 16 or 17e, this can take many seconds and sometimes a few minutes
* When the pod is not connected, neither automatic nor manual commands can be sent to the pod to modify insulin delivery
* No solution to this issue is known
* There is a work-around to keep these pods more connected by issuing a keep-alive message before the 3-minute BLE disconnect; but it uses extra battery for the phone.

* Although it does increase the number of messages to the pod slightly, this is not thought to be a big issue. Pods with marginal batteries are as likely to fault without this feature as with the feature.

## Do I still need a PDM with Omnipod Loop?

No, pods are monogamous little creatures. They will pair with only one device at a time for safety reasons...so a pod is either paired with a PDM or your *Loop* app on your iPhone. In other words, your PDM can stay in the diabetes closet while you are Looping. You cannot use the PDM for a pod that has been activated with the *Loop* app. That doesn't mean you should get rid of your PDM if you have one. Instead, keep it for backup situations if you lose your phone. See below for what to do if you lose your phone or RileyLink.
You don't need a PDM to use Pods with your OS-AID system but you might need a PDM serial number registered to your Insulet account to get replacements for failed Pods.

## Is there an increase in pod failures on Loop?

This section used to be accurate. But there is an issue with some Atlas DASH pods that we don't understand, but we have statistics indicating a big increase in frequency of faults (Pods starting to scream). See [Increase in DASH Faults](#increase-in-dash-faults).

There is more communication between the pod and the controller (your *Loop* phone) than is typical with the PDM (Insulet provided controller). This increases the load on the pod battery. Most people have no increase in pod failures, but there are steps to take to limit "extra pod battery use". Every time the *Loop* app requests an update of the pod state or issues a command (bolus, basal schedule, temp basal), messages are exchanged with the pod.

* Set your correction range to be 10 to 20 mg/dL (0.5 to 1.1 mmol/L) instead of a single number
* The number of commands will be reduced
* The pod state is updated every 3 minutes for DASH and every 5 minutes for Eros
* If uncertain communications are detected such that the *Loop* app cannot determine if a dosing command sent to the pod was actually received, the app will try once a minute to get a response
* The combination of Eros pods with a RileyLink device with poor signal leading to uncertain comms may cause excessive battery use and contribute to pod faults
