Issue: How to fix “Check the PIN and try connecting again” Bluetooth error in Windows 10?
Hey, I need help with the connection and PIN error. I cannot pair Bluetooth devices, and I get the Check the PIN error. There is no problem with the device because it has batteries, it works properly. I can find the piece in settings, but when I try to pair them after the Connecting window, the “Check the PIN and try connecting again.” error shows up. The PIN form is not showing up, so the process is not going as it is supposed to. Can you help me solve this, so I can pair the device normally?
Solved Answer
“Check the PIN and try connecting again” Bluetooth error in Windows get reported pretty often and in many cases involves Bluetooth keyboards.[1] Once the device is deleted and the user wants to connect it again to the PC, the pairing can't happen. Trying to connect to the device via settings ends in the error and the long process of pairing devices.
The issue can be frustrating because the problem occurs out of nowhere, and the process is not loading as it properly should. When the Bluetooth option gets disabled, or some particular files get damaged in the system, functions like this fail. Of course, if you run Windows 10 on the machine, the recent faulty update can be blamed.[2]
In many cases, the issue can be solved by restarting the machine, so all the functions run as normal. Other reasons why the issue is present can involve some system issues deeper. You might receive the “Check the PIN and try connecting again” error in Windows 10 without noticing that other system features are failing too.
The problem with the error is constant reoccurrence, but the situation can be fixed. This problem shouldn't be related to any serious issues like cyber threats or malware.[3] However, some of the reasons can require particular solutions. The error can arise when the pairing is not proper in the first place. So if you try to pair the device that was already connected before, the problem may reside in the software or hardware problems.
Another thing that we already mentioned – the disabled option for Bluetooth connections can trigger the problem with new pairings. If your computer is in airplane mode, these connections cannot happen also. WiFi, NFC, Bluetooth, cellular, and other connections get disabled in such mode. If you try to solve the issue and fail, you might want to run FortectMac Washing Machine X9 to check for file damage and repair functions needed for normal PC performance.
