My Square Up suddenly decided to stop working. I tried to forget the device and try to connect again but it wouldn't even flash orange lights. Then, it had trouble being recognized by bluetooth.. After a while, it got recognized and started flashing orange lights again...but it still won't connect. There's no response (no loading) and it continuously flashes orange lights without stopping unless i press it again. I've tried everything (uninstalling and reinstalling, charging my device, turning on/off wifi, data, and bluetooth, restarting my phone). Please help..Thanks&nbsp;</P> Sun, 21 Sep 2025 12:21:21 GMT UnicornCo 2025-09-21T12:21:21Z https://community.squareup.com/t5/Hardware-Setup-Troubleshooting/How-can-I-troubleshoot-my-contactless-and-chip-card-reader-so-it/m-p/135731#M6497 <P><EM>This reply was created from merging an existing thread:&nbsp;Square Up stopped working and wont connect</EM></P> <P>&nbsp;</P> <P>Hello.

This is frustrating for sure. I'm glad you posted here and let us know.</P> <P>&nbsp;</P> <P>In most circumstances, pairing issues can be resolved with these <A href="http://squ.re/2A22hpl" target="_blank">troubleshooting steps</A>, but there is an occasional situation in which the reader may need to be <A href="https://squ.re/2I6FhY7" target="_blank">warrantied</A> and swapped for a new one.&nbsp;</P> <P>&nbsp;</P> <P>One thing I do want to ensure is that you are attempting to pair the reader directly from the Square app in lieu of from your devices Bluetooth Settings - a common misstep&nbsp;that we see from time to time. It's also worth checking to see if your device has any pending software updates available. We often push out periodic app&nbsp;software updates that coincide with Apple &amp; Android, which can deprecate the app if one is updated&nbsp;without the other.</P> <P>&nbsp;</P> <P>Let me know if any of this steps help resolve the issue! Our <A href="http://squ.re/2tnoRAz" target="_blank">Support Team</A> is standing by if you need any help at all.</P> <P>&nbsp;</P> <P>&nbsp;</P> Mon, 14 Oct 2019 23:33:46 GMT https://community.squareup.com/t5/Hardware-Setup-Troubleshooting/How-can-I-troubleshoot-my-contactless-and-chip-card-reader-so-it/m-p/135822#M6498 Joe 2019-10-14T23:33:46Z
