Crack the codes of pairing failure
When pairing fails, users sometimes can find an error code such as ‘6101’ on the screen beside the ‘pairing failed’ error message.
What does it mean? Let’s delve into the error codes and crack the codes of pairing failure.
eWeLink app supports a variety of types of devices. The first thing you do before you can control a newly purchased product is pairing. Different devices allow diversified pairing methods.
In summary, there are four most common pairing methods. They are ‘Quick Pairing’, ‘Compatible Pairing’, ‘QR scanning’, and ‘Bluetooth Pairing’.
Due to the different mechanisms of each pairing method, errors are likely to happen anywhere. For your convenience, eWeLink app has specified the error code on the page of pairing failure.
Error codes are categorized according to the pairing method.
Quick Pairing
The error codes for quicking pairing starts with the two digits ‘61’.
6101/6106/6107 Router settings
These error codes mean that eWeLink app cannot find the devices or cannot assign IP addresses to the devices. To fix them, enable DHCP.
6102/6103/6104 Communication error
Failed to receive the required data or device is not responding in the process of searching for, registering, or connecting the device. The solution to this type of error is to try again. If the
pairing fails again, please try again with a personal mobile hotspot to test the WiFi functionality of the device.
6105 Timeout
The app fails to find any devices within 3 minutes. Check if the device is still blinking twice and pauses repeatedly. If not, it has quitted quick pairing mode. Please try again.
6108 Unknown error
Please submit feedback in eWeLink app if this error continues to occur.
Compatible Pairing
The first two numbers ‘62’ means you are trying to pair the devices in the compatible pairing mode. Compatible pairing mode is the method for you to manually connect to a WiFi hotspot generated by the device to tell the device which WiFi SSID and password could be used to connect to eWeLink servers.
6201 Device hotspot failure
The app cannot acquire the SSID of the device. Power off the device, set the device in compatible pairing mode again, and pair again.

6206/6207 Server error
These errors happen when the app fails to register the devices or there is no response from the server. Please submit feedback in eWeLink app and wait for eWeLink to email you about the recovery time.
6208 Timeout
The app fails to find any devices within 3 minutes. Check if the device is still blinking quickly constantly. If not, it has quitted compatible pairing mode. Please try again
QR scanning Pairing(SoftAP)
The QR scanning method applies softAP technology which connects to the access point generated by the device by scanning its QR code. It is similar to compatible pairing mode, so
it also starts with the two numbers ‘62’.
6210/6211/6212 Communication error
When the app is communicating with the device, the device cannot connect the access point of the device, cannot get device information or the device is not responding. Please try again.

6217 Device hotspot failure
The app cannot acquire the SSID of the device. Power off the device, scan its QR code again, and pair again.
Bluetooth Pairing
If an error code starts with ‘63’, then you are trying to pair a device in the Bluetooth pairing mode. Please make sure that your device supports Bluetooth pairing before you use this method.
