Square Reader Will Not Pair With iPhone

sleepymonk — Sat, 20 Sep 2025 18:40:05 GMT

I’m having trouble pairing my Square Reader (2nd generation, white, contactless + chip) with my iPhone running iOS 18.4.1.
I’ve downloaded the Square Point of Sale app and followed all pairing instructions:
Bluetooth is on and no other devices are connected.
Reader is fully charged.
I’ve held the button until the orange lights flash, placed the reader right next to the phone, and waited for a prompt.
I’ve also performed a reset by holding the button for 20 seconds until red lights flash.
I’ve restarted my phone and tried again inside the app.
Despite all of this, the reader still won’t pair — it just stays in orange flashing mode. The app gives pairing instructions but never completes the connection.
Could this be a firmware or hardware issue with the reader? I would appreciate your help resolving this.

Hi, @sleepymonk ! I am going to highlight a full, comprehensive troubleshooting guide. Please let me know if you have tried everything I have listed and if it still isn't working, I will go ahead and flag this to our engineers.

1. Verify Reader Status

First, let's confirm the reader's current state:

Orange flashing lights indicate pairing mode
If you see 4 red lights, the reader needs charging
A solid orange light means it's charging

2. Advanced Reset Steps

Since you've already tried the basic reset, let's try these additional steps:

Deep Reset Procedure:
- Hold the button for 20 seconds until red lights flash
- Release the button
- Wait 10 seconds
- Hold the button again for 3 seconds until orange lights flash
Clear Bluetooth Cache:
- Go to iPhone Settings > Bluetooth
- If you see the Square Reader listed, tap the (i) icon
- Select "Forget This Device"
- Turn Bluetooth off
- Restart your iPhone
- Turn Bluetooth back on
Square App Reset:
- Delete the Square Point of Sale app
- Restart your iPhone
- Reinstall the app from the App Store
- Sign in to your account
- Try pairing again

3. Check Compatibility

Confirm your Square Reader model number (on the back of the device)
Verify iOS compatibility on Square's website
Ensure your Square Point of Sale app is the latest version

4. Environmental Factors

Move away from other electronic devices
Try pairing in a different location to rule out interference
Ensure both devices are within 1-2 feet of each other during pairing

5. Hardware Check

To verify if it's a hardware issue:

Try pairing the reader with a different iOS device
If possible, try a different Square Reader with your iPhone

Thanks for this post! I just recently had this issue on iPhone 16 and #2 Step 1 Deep Reset Procedure on the square reader worked!
