# Changes Needed Commonly Among Models

This chapter explains the steps required to run applications, originally developed for other devices using this SDK, on the following models:

- `ASR-M24D`
- `ASR-M30S`
- `ASR-025S`

---

## SDK Replacement

Please refer to the table below for the SDK versions that support each model. If you are using an older SDK, replace it with the latest one before proceeding.

|  Model   | Supported SDK Version |
| -------- | --------------------- |
| ASR-M24D | 5.2.0 or later        |
| ASR-M30S | 5.7.0 or later        |
| ASR-025S | 5.8.0 or later        |


---

## Adding xcframework

Replace the following frameworks with the ones included in the latest SDK:

- `AsReaderBLESDK.framework` or `AsReaderBLESDK.xcframework`
- `AsReaderDockSDK.framework` or `AsReaderDockSDK.xcframework`

For detailed instructions, refer to "[Add SDK](../1_how_to_use.md#adding-the-sdk)".

---

## Adding AsReader Protocol

Add the supported device protocols to the `Supported external accessory protocols` in `Info.plist`.

|      Device       |           Protocol to Add            |
| ----------------- | ------------------------------------ |
| ASR-M24D          | `jp.co.asx.asreader.6dongle.barcode` |
| ASR-M30S<br> 025S | `jp.co.asx.asreader.slim`            |

## Connection Handling

For the models listed [here](./common.md#changes-needed-commonly-among-models), `readerConnected:` is called automatically upon connection, so calling `setReaderPower` is not required and executing it does not power the device on / off as it does on the other models.  
For the models not on the list, `setReaderPower` must be executed after `plugged:`.  

```objectivec
- (void)plugged:(BOOL)plug {
    if (plug) {
        AsReaderInfo *info = [AsReaderInfo sharedInstance];
        if (info.isEnginePowerAlwaysOn) { // The models on the list
            // No need to call setReaderPower
            // readerConnected is called automatically
        } else { // Other AsReader devices
            // Call setReaderPower here
        }
    } else {
        // Handle disconnection
    }
}

- (void)readerConnected:(int)status {
    if (status) {
        // Power-on successful
    } else {
        // Power-on failed
    }
}
```

## Beep Control Upon Connection

Beep and vibration can be controlled using the method below. For ASR-M30S / ASR-025S, all parameters other than `isBeep` are ignored.

```objectivec
- (BOOL)setBeep:(BOOL)isBeep
     vibration:(BOOL)isVibration
 batteryGaugeLed:(BOOL)isbatteryGaugeLed
   barcodeAimer:(BOOL)isBarcodeAimer
barcodePowerOnBeep:(BOOL)isBarcodePowerOnBeep;
```

---

```{important}
For the models on [the list](./common.md#changes-needed-commonly-among-models), **the trigger key must be pressed to wake the device from its sleep state**.
```
