# Set up a Bluetooth LE button
This article is written for: ❌ Zello Work ✅ Zello Friends & Family
A Bluetooth Low Energy (BLE) push-to-talk (PTT) button lets you talk on Zello without holding the on-screen talk button, or while Zello runs in the background. This guide shows you how to pair a BLE accessory and add its button to Zello on your iPhone or iPad.
### **Before you start**
- **Use a supported accessory.** Zello only recognizes BLE buttons it has certified. Check the [Zello certified hardware page](https://zello.com/hardware/headsets-buttons-mics/) to confirm your device is supported before setting it up.
- **Charge the accessory** and turn it on.
- **Make sure the button isn't already paired to another phone or tablet.** A BLE button that's still bonded to another device often won't be discovered. If needed, reset the accessory following the manufacturer's instructions before you begin.
### **Step 1: Pair the accessory with your device**
Following the manufacturer's instructions, put the accessory in pairing mode and pair it with your iPhone or iPad.
### **Step 2: Add the button in Zello**
1. Open Zello and tap your **profile picture** in the top-left corner.
2. Select **Settings**.
3. Select **Push-to-talk buttons**.
4. Tap **Add New Device**. Your accessory's name will appear.
5. When prompted, press and release the button on your accessory that you want to use for push-to-talk. Zello detects the press and adds that button to your Push-to-talk buttons list, where it now appears.
### **Step 3: Test the button**
Open the **Echo** contact and press your accessory's button to record a short message. Echo plays your message back to you, so you'll immediately know the button is transmitting correctly.
### **Optional: Assign the button to a specific contact or channel**
By default, the button sends to whichever contact or channel screen you last had open. To lock it to one recipient:
1. Go to **Settings \> Push-to-talk buttons** and tap your accessory's name.
2. Open the button's contact menu and tap **Select**.
3. Choose the contact or channel you want the button to always talk to.
### **Troubleshooting**
- **Your accessory doesn't appear under Add New Device**: Confirm it's a [certified Zello accessory](https://zello.com/hardware/headsets-buttons-mics/), that it's charged and in pairing mode, and that it isn't still connected to another phone. Toggling Bluetooth off and on, or restarting the app, can also help.
- **The button paired but won't transmit or keeps disconnecting**: Power-cycle the accessory, then remove it from the **Push-to-talk buttons** list and add it again. If it still won't reconnect, restart your device.
