🐛 BLE writeCharacteristicWithResponseForService not working on Android while functioning on iOS

[Mochamad-Rizky]

Prerequisites

• I checked the documentation and FAQ without finding a solution
• I checked to make sure that this issue has not already been filed

Expected Behavior

1. The receipt printing function should work consistently across both iOS and Android platforms
2. The BLE write characteristic operation should complete successfully
3. A success message should be displayed upon successful printing

Current Behavior

iOS: Works as expected, successfully prints receipts

Android:

1. No response from the write characteristic method
2. No error messages are thrown
3. The success/error callbacks are not triggered

Library version

3.4.0

Device

Android 13

Steps to reproduce

1. Connect to BLE device
2. Attempt to print receipt using the provided code
3. Observe that iOS successfully prints while Android fails silently

Formatted code sample or link to a repository

const printReceipt = async () => {
    if (!device || !serviceUUID || !characteristicUUID) {
        toast.error('Belum terhubung dengan perangkat');
        return;
    }

    try {
        const printCommand = await getPrintCommand();
        const bufferPrint = Buffer.from(printCommand).toString('base64');
        console.log(serviceUUID, characteristicUUID, device);
        
        await device.writeCharacteristicWithoutResponseForService(
            serviceUUID,
            characteristicUUID,
            bufferPrint
        );
        
        toast.success('Print berhasil');
    } catch (error) {
        toast.error(`Print gagal: ${error}`);
    }
};

Relevant log output

when console log output (console.log(serviceUUID, characteristicUUID, device));

Additional information

When attempting to print receipts using BLE communication, the writeCharacteristicWithResponseForService method works as expected on iOS devices but fails silently on Android devices. The method call does not trigger any response or error on Android, preventing the receipt printing functionality.
