Check Compatibility with an Older USB-C EMT Module - Echo Meter Touch

The compatibility of old USB-C Echo Meter Touch modules with iOS or iPadOS devices depends on the module's firmware. Otherwise, compatibility is the same as for new modules.

1. Check whether your phone or tablet runs iOS/iPadOS, Amazon Fire OS, or Android.
   • For iOS/iPadOS devices, go to Step 2
   • For Fire OS devices, go to Step 4.
   • For Android devices, go to Step 5.
2. Determine whether your iOS or iPadOS device has a Lightning port or a USB-C port by looking at its charging cable.
   
   
   
   See Types of Data Ports Found on Phones and Tablets for additional help identifying Lightning and USB-C ports.
   • If your device has a Lightning port, it is not compatible with USB-C EMT modules.
   • If your device has a USB-C port, it is compatible with your USB-C EMT module, but your module may need a firmware update. Go to Step 3.
3. Determine when your EMT module was sold.
   • If your EMT module was sold after April 2024, it should have the latest firmware with iOS/iPadOS compatibility.
   • If your EMT module was sold prior to April 2024, or if you are unsure, your EMT module may have an older firmware version that does not support iOS/iPadOS. Go to Update the Firmware on USB Modules to Add iOS Compatibility.
4. Check if your Fire OS device is on our list of known compatible devices.
   • If your Fire OS device is not on the list, it is not compatible with any EMT module.
   • If your Fire OS device is on the list, it is compatible with new EMT modules and does not require a USB adapter. You may use a USB-C extension stub or cable if you want.
5. Check to see if your Android device is on our list of known compatible devices.
   • If your Android device is not on the list, go to Step 6.
   • If your Android device is on the list, it is compatible with EMT modules, but it may need a USB adapter. Go to Step 7.
6. Check if your Android device meets the general requirements for Android compatibility.
   • If your Android device meets all requirements, it may be compatible, but we cannot guarantee compatibility with devices we have not tested. If you still want to try using an EMT with your device, go to Step 6.
   • If your Android device fails to meet any requirement, it is not compatible with any EMT modules
7. Check which data port your Android device has by looking at its charging cable.
   
   
   See Types of Data Ports Found on Phones and Tablets for additional help identifying the data port.
   • If your device has a USB-C port, you do not need a USB adapter. You may use a USB-C extension stub or cable if you want.
   • If your device has a Micro-USB port, you need a USB on-the-go (OTG) adapter. See Adapters for Echo Meter Touch Modules for more information on finding a suitable adapter.
