Hi, thanks for reaching out. Could you also share the code used for discover a reader?

Thank you, looks normal to me. Which log did you get from handleConnectBluetoothReader ?

shadow glen Jun 30, 2025, 4:51 AM

This is the log I believe

I have 2 terminals, and below is the log for another:

 }

Both of them don't work. I have 2 iPads too and I have tried all permutations.

naive agate Jun 30, 2025, 4:56 AM

#

Could you elaborate why are you doing this?

Platform.OS === 'ios' ? 'bluetoothScan' : 'usb'

shadow glen Jun 30, 2025, 4:58 AM

#

I want android tablets to use usb which I found to be more reliable and on iOS I believe usb doesn't work so I used bluetoothScan as per the docs.

naive agate Jun 30, 2025, 4:59 AM

#

Ah I see, but let's say if you use bluetooth scan with Android, do you see the same issue?

shadow glen Jun 30, 2025, 5:01 AM

#

I haven't tested that, give me 10 minutes.

naive agate Jun 30, 2025, 5:06 AM

#

Sure no rush. Just to share that not much we can tell from our internal log, the readere behaves like the collectPaymentMethod purely wasn't called

shadow glen Jun 30, 2025, 5:57 AM

#

Thank you for your patience.

Yes I can confirm that when I discover readers via bluetoothScan even on android it hangs.

#

This is the reader that was discovered:

Just tested it again, and it worked on android, but it did hang the first time.

Hmm so it's the unstable Bluetooth connection

shadow glen Jun 30, 2025, 6:18 AM

#

The terminal is very close to the tablet. So distance is not the issue.

When testing, I try my best to turn off other tablet's bluetooth, just to make sure only 1 device is connecting.

Anything else that might make the connection unstable.

There is a beeping noise as soon as the collectPaymentMethod is called,, like the one that plays after successful payment.

naive agate Jun 30, 2025, 6:24 AM

#

Sorry just rubber-duck-debugging but can you try in an iPhone?

#

your POS app

#

Was iPad never able to connect even after a few tries?

shadow glen Jun 30, 2025, 6:28 AM

#

Initially, when building the app, it would connect and work flawlessly, only hanging like once or twice a week. But suddenly it started hanging on every payment. There have been no code changes, so I thought it was a terminal issue, so I bought another m2 reader, it didn't work. So I thought my iPad was damaged somehow so I bought another iPad and nope it didn't work.

I don't have an iPhone, sorry.

naive agate Jun 30, 2025, 6:30 AM

#

Interesting

#

If you restart readers and the iPads, would it still completely not working?

shadow glen Jun 30, 2025, 6:33 AM

#

yes, I have restarted the terminal and tablets multiple times. I even reset the iPad.

naive agate Jun 30, 2025, 6:33 AM

#

Also I noticed many Bluetooth issue fixed in 2.01.00.21. Could you check which firmware version your M2 readers are in?

#

https://docs.stripe.com/terminal/readers/stripe-m2

Stripe Reader M2

Learn about the Stripe Reader M2 Bluetooth reader.

shadow glen Jun 30, 2025, 6:34 AM

#

"deviceSoftwareVersion": "2.01.00.31-SZZZ_Prod_US_v12-481001",
Is this the firmware version?

naive agate Jun 30, 2025, 6:35 AM

#

Yep

#

hmm

#

Do you receive any onDidStartReaderReconnect event?

#

And do you turn on autoReconnectOnUnexpectedDisconnect ?

shadow glen Jun 30, 2025, 6:49 AM

#

I though autoReconnectOnUnexpectedDisconnect was true by default?

No, I have not manually set that to true.

onDidStartReaderReconnect Just tried this and no this one doesn't trigger.

I also tried to get connected reader just before payment via const readerStat = await getConnectedReader();
It logs

#

Should the status be offline?
On android, status is unknown.

naive agate Jun 30, 2025, 7:06 AM

#

Yes that's weird. I suppose that should be online

#

Sorry I am running out of idea

Double check (or attempt revert anyway) there wasn't any code changes.
Ask Stripe Support to replace the M2 reader you just bought.

shadow glen Jun 30, 2025, 7:09 AM

#

Does that status indicate it's connection to the internet or its power status?

If it is internet then running getConnectedReader just before retrievePaymentIntent also says offline but retrievePaymentIntent does indeed return back a response.

naive agate Jun 30, 2025, 7:11 AM

#

more of connection between reader <> POS app

#

aka the Bluetooth connection

#

By any chance do you have 2 POS app (2 deployed versions of it on 2 different devices) trying to connect to a same M2 reader?

shadow glen Jun 30, 2025, 7:14 AM

#

Yes, but I closed the app and turned bluetooth off on another one.
Will that affect?

#

Oh they are not trying to connect to the same reader.

naive agate Jun 30, 2025, 7:17 AM

#

Alright, just for troubleshooting but if you open iPad's Bluetooth Settings (not your app), can you connect the the reader?

shadow glen Jun 30, 2025, 7:17 AM

#

yes I can.

#

It shows STRM26146006451 this name and I can connect to it.

naive agate Jun 30, 2025, 7:20 AM

#

Okie now when you can reproduce on your POS app, could you share the full log from your app, up untill you are supposing to call collectPaymentMethod? (Put a breakpoint there and capture the log when it stops at collectPaymentMethod)

shadow glen Jun 30, 2025, 7:22 AM

#

I'll need some time. This thread won't close, right?

naive agate Jun 30, 2025, 7:41 AM

#

We may close when my colleage take over. But you can always open a new thread and it will link back to this thread
