If you purchased your Herelink before the activation code became required, it wouldn’t have come with the activation code. In these cases, you have to contact the reseller you acquired it from and request an activation code. ---

@Michael_Oborne could you please help with a problem. I have a Herelink unit purchased from AliExpress. Eric Xie was kind enough to assist in providing an activation key which was not on the box cover. I get a Cannot Register Device error even though the IP address and 5 ghz internet connection are recognised. Also - what region should I select ? Please help! Thanks Raja ---

Michael, I have got it working now. The IP address needed a change and the unit was showing a different time zone than the one I had set. Have got it registered and updated. Now for the air unit. Any special instructions on updating and pairing the air unit or do I just follow the guides on the site? Thanks, Raja ---

[Andreas\_Diaz](https://discuss.cubepilot.org/u/Andreas_Diaz) [1m](https://discuss.cubepilot.org/t/herelink-new-system-update/7220) Is anyone having problems pairing the air unit after updating to the latest version: BRU01210730 I did this update because qgroundcontrol said that the current version wasn’t the 3.3 version, so I update and then I realized that the pairing with the air unit was gone, and after trying to re-pair I didn’t succeded. There is a new UI by the way so I don’t know if the steps to setup changed or something… PLEASE HELP! ---
